As shown in FIG. 1, a medical image processing apparatus  1  is connected to an image collecting apparatus  2  to collect a medical image through a communication network such as LAN or internet. The connection to the communication network may also be a wire connection or wireless connection. The image collecting apparatus  2  is an X ray CT scanner, CR apparatus, ultrasonic diagnostic apparatus, or MRI (Magnetic Resonance Imaging) apparatus, and one set or a plurality of sets can be connected to a medical image processing apparatus  1 . Thereby, the digital data of the medical image collected by the image collecting apparatus  2  is transmitted to the medical image processing apparatus  1  through the communication network N.

The number of sets of these external devices are not particularly limited.  
         [0038]    [0038]FIG. 2 is a block diagram showing the functional structure of the medical image processing apparatus  1 . Referring to FIG. 2, the internal structure of the medical image processing apparatus  1  will be detailed below.  
         [0039]    As shown in FIG. 2, the medical image processing apparatus  1  is structured by a CPU  11 , input section  12 , display section  13 , RAM  14 , storing section  15  having a recording medium  15   a , communication control section  16 , and image processing section  17 , and each section is connected through a bus.  
         [0040]    The CPU (Central Processing Unit)  11  reads each kind of control program stored in the storing section  15 , and according to the control program, the movement of each section is centralized-controlled. Further, Further, the CPU  11  conducts each kind of processing including the image output processing A, image output processing B and image output processing C, which will be described later, according to the read control program, and stores the processing result in the RAM  14  and displays it on the display section  13 . Then, the processing result stored in the RAM  14  is saved in a predetermined destination of the saving of the storing section  15  or recording medium  15   a , or transmitted to the external devices connected to the communication network through the communication section  16 .  
         [0041]    The input section  12  is structured by providing with a keyboard having a character/alphanumeric input key, cursor key, and each kind of function key, and a mouse which is a pointing device, and the pressed signal of the key on the keyboard and the operation signal by the mouse are made an input signal, and outputted to the CPU  11 . Alternatively, the input section  12  is structured by a touch panel which makes the position information inputted when the finger or exclusive use stylus pen touches the transparent sheet panel covering the display image plane of the display section  13 , an input signal, and outputs it to the CPU  11 .  
         [0042]    The display section  13  is structured by a LCD (Liquid Crystal Display) or CRT (Cathode Ray Tube), and according to the direction of the display signal inputted from the CPU  11 , it displays the image on the display image plane.  
         [0043]    The RAN (Random Access Memory)  14  is a temporary storing area for the system program which is read from the storing section  15  and can be operated by the medical image processing apparatus  1 , each kind of processing program, input or output data, and parameter, in each kind of processing which is operated and controlled by the CPU  11 .  
         [0044]    The storing section  15  is structured by a HD (Hard Disk) or nonvolatile semiconductor memory, and stores the system program corresponding to the medical image processing apparatus  1 , and each kind of processing program which can be operated on the system program, and the data processed by these programs. The program is stored in the form of program code which can be read by the computer, and the CPU  11  successively conducts the movement according to the program code.  
         [0045]    Further, the recording medium  15   a  is structured by a magnetic or optical recording medium, or nonvolatile memory such as a semiconductor, and stores each kind of data including the program data or the medical image data received from the image collecting apparatus  2 , or the other medical image processing apparatus  1 . The recording medium  15   a  is one which is fixedly provided in the storing section  15  or detachably installed. To the recording medium  15   a , the data of the medical image and the information relating to the medical image data (patient name, photographic part) correspond, and they are stored in the medium as the medical image information.  
         [0046]    In the present embodiment, the recording medium  15   a  is structured by having a default parameter table  151  corresponding to the output device and the photographic part. FIG. 3 is a view showing an example of data storage in the default parameter table  151 . As shown in FIG. 3, in each line of the default parameter table  151 , the processing parameter (for example, “p11, q11”, as the processing parameter corresponding to the output device e 1  and photographic part b 1 , and “p12, q12”, . . . , as the processing parameter corresponding to the output device e 1  and photographic part b 2 ) for each photographic part corresponding to the output device (for example, “e1”, “e2”, . . . ) is stored. In the row of the default parameter table  151 , the processing parameter (for example, “p11”, q11”, as the processing parameter corresponding to the photographic part b 1  and output device e 1 , and “p21, q21”, . . . , as the processing parameter corresponding to the photographic part b 1  and output device e 2 ) for each output device corresponding to the photographic parts (for example, “b1”, “b2”, . . . ) is stored. When the processing parameter stored in the position at which the output device line and photographic part line are crossed, considers the gradation characteristic of the output device and frequency characteristic, and displays (outputs) the image of certain photographic part, the parameter is an image processing parameter set in the default under the assumption that the optimum image processing can be conducted.  
         [0047]    The communication control section  16  is structured by the LAN adapter or router, or TA (Terminal Adapter), and conducts the communication control to each apparatus connected to the communication network, for example, the other medical image processing apparatus  1 , image collecting apparatus  2 , image display apparatus  3 , or printer  4 .  
         [0048]    The image processing section  17  conducts the image processing such as the rotation processing, gradation processing, or frequency processing on the medical image data inputted from the image collecting apparatus  2 . Further, it conducts the compression processing which compresses the image data in a predetermined coding format, extending processing which decodes the compressed image data and extends it, format conversion processing into the adopted image format, or conversion processing for displaying on the display section or outputting by the printer.  
         [0049]    Next, the operation will be described. Referring to the flowchart in FIG. 4, the image output processing A which is conducted by the medical image processing apparatus  1  will be described.  
         [0050]    When a button for the output destination is operated by the operation of the mouse or touch operation on the image output operation image plane, and the apparatus of the output destination of the photographed image (medical image) displayed on the image plane is specified (step S 1 ), the CPU  11  discriminates the output device number by the operated button for the designation of output, and refers to the medical image information stored in the storing medium  15   a  and discriminates the photographic part of the image which is an object of the output (step S 2 ). Next, the CPU  11  refers to the default parameter table  151  and obtains the processing parameter corresponding to the output device number and the photographic part discriminated in step S 2  (step S 3 ). For example, when it is discriminated that the output device number is ek, and photographic part is bm, from the default parameter table  151  (refer to FIG. 3), the processing parameters pkm, qkm are obtained. Then, the CPU  11  conducts the image processing on the image which is the object of the output according to the processing parameter obtained in the image processing section  17  (step S 4 ), and displays the image processed image on the image output operation image plane (step S 5 ).  
         [0051]    After the image processed image is displayed on the image output operation image plane, the change of the processing parameter is designated, and when the new parameter is inputted (step S 6 : YES), the CPU  11  calculates the new processing parameter according to the inputted parameter (step S 7 ), conducts the image processing on the image which is the object of the output (step S 8 ), and displays the image processed image on the image output operation image plane (step S 9 ). In step S 10 , until the output button is pressed, the CPU  11  repeatedly conducts the processing of the step S 6 -S 10 . Then, when the output button is pressed and the output of the image is designated (step S 10 : YES), the CPU  11  outputs the image processed image to the designated output device (step S 11 ).  
         [0052]    After the image is outputted, the CPU  11  judges whether the change of the processing parameter is conducted in the step S 6 , and when it judges that the change of the parameter is not conducted (step  12 : NO), the image output processing A is completed. When the CPU  11  judges that the change of the parameter is conducted (step  12 : YES), the CPU  11  re-writes the processing parameter in the default parameter table  151  corresponding to the output device and photographic part to the processing parameter calculated in the step S 7  (step S 13 ), and completes the image output processing A.  
         [0053]    [0053]FIG. 5 is a view showing an example of the image output operation image plane  131 . As shown in FIG. 5, on the left side of the image plane of the image output operation image plane  131 , the photographic image outputted to the outside output device is displayed. On the lower portion of the image plane, the buttons for the output destination such as the “printer 1”, “printer 2”, and “host 1” are displayed, and when the button for the output destination is pressed, the image processing is conducted on the photographic image by the processing parameter corresponding to the output destination, and the image is displayed. Then, the “output“button arranged on the upper portion of the button for the output destination is pressed, the image on which the image processing is conducted is outputted to the output device such as the CRT connected to the designated printer or designated host. On the right side of the image plane, an input space of the parameter is displayed. In step S 6  in FIG. 4, the value is selected from the input space of this parameter, and when “change” button is pressed, in the step S 7 , the processing parameter corresponding to the output destination and photographic part designated in step S 1  is calculated according to the inputted numeric value, and in the step S 13 , the default parameter  151  is re-written.  
         [0054]    As described above, according to the medical image processing apparatus  1 , the CPU  11  refers to the default parameter table  151  when the output destination of the photographic image is designated, obtains the processing parameter corresponding to the designated output device and the part of the photographic image, conducts the image processing on the photographic image according to the processing parameter, and outputs it to the designated output device. Accordingly, in the system in which a plurality of output devices are connected, in the case where the gradation characteristic of each output device or frequency characteristic is different, when the optimum processing parameter is stored in the default parameter table  151 , it is not necessary that the processing parameter is set again every when the image is outputted by the output device, and the image output operation becomes easy.  
         [0055]    (The second Embodiment)  
         [0056]    The second embodiment will be described below. In the present embodiment, the recording medium  15   a  is structured by having the default parameter table  152  and output device characteristic table  153  in the inside. FIG. 6 is a view showing the data storing example of the default parameter table  152  which stores the default processing parameter when the photographic image is displayed in the output device provided in the present medical image processing apparatus  1  by making it correspond to the photographic part. As shown in FIG. 6, the default parameter table  152  has a photographic part area  152   a  which stores the identification code uniformly allotted for specifying the photographic part (for example, “b1”, “b2”, “b3”. . . . ) as the “photographic part”, and a parameter area  152   b  which stores the data (for example, “pm1, qm1”, “pm2, qm2”, “pm3, qm3”, . . . ) expressing the corresponding processing parameter as “parameter”.  
         [0057]    [0057]FIG. 7 is a view showing a data storing example of the output device characteristic table  153  which stores the output device connected to the present medical image processing apparatus  1  and its gradation characteristic and frequency characteristic, by making them correspond to each other. As shown in FIG. 7, the output device characteristic table  153  has an output device number area  153   a  which stores the identification code (for example, “e1”, “e2”, “e3”, . . . ) uniformly allotted for specifying the output device as “output device number”, gradation characteristic area  153   b  which stores the data (for example, “S1”, “S2”, “s3”, . . . ) expressing the gradation characteristic corresponding to the output device, as “gradation characteristic”, and frequency characteristic area  153   c  which stores the data (for example, “T1”, “T2”, “T3”, . . . ) expressing the frequency characteristic corresponding to the output device as “frequency characteristic”.  
         [0058]    Further, although it is not specifically shown, the recording medium  15   a  stores the output characteristic in the output device provided in the present medical image processing apparatus  1  (for example, the frequency characteristic SD, gradation characteristic TD). In this connection, because the structure of the other medical image processing apparatus  1  in the present embodiment is the same as the first embodiment described above, the same numeric code is attached to each component, and the graphic display and explanation of the structure are omitted.  
         [0059]    Referring to the flowchart in FIG. 8, the image output processing B conducted by the medical image processing apparatus  1  will be described below. When the output designation button is operated by the operation by the mouse or touch operation on the image output operation image plane and the device of the output destination of the medical image displayed on the image plane is designated (step S 21 ), the CPU  11  discriminates the output device number by the operated output destination button, and refers to the medical image information stored in the recording medium  15   a , and discriminates the photographic part of the image which is the object of the output (step S 22 ). Next, the CPU  11  refers to the default parameter table  152  obtains the processing parameter corresponding to the discriminated photographic part in the output device (output device in which the output image is already confirmed, hereinafter, it is described as the present output device) provided in the present medical image processing apparatus  1  (step S 23 ). For example, when the photographic part is discriminated as bm, the processing parameters pmm, qmm are obtained by the default parameter table  152 .  
         [0060]    Next, the CPU  11  reads the gradation characteristic and frequency characteristic of the designated output device from the output device characteristic table  153 , and calculates the processing parameter (step S 24 ). For example, when the image data is outputted from the output device of the output device number e 1 , the gradation characteristic SD and frequency characteristic T 1  of the output device e 1  are obtained from the output device characteristic table  153 , and when the difference of the gradation characteristics SD and S 1  of the present output device is Δs1, and the ratio T 1 /TD of the frequency characteristics TD and T1 of the present output device is Rt1, the processing parameters pmm+Δs1, and qmm×Rt1, are calculated. Then, the CPU  11  conducts the image processing at the processing parameter pmm+Δs1, and qmm×Rt1 obtained in the image processing section  17  (step S 25 ), and the image processed image is displayed on the image output operation image plane (step S 26 ). When the output button is pressed and the output of the image is designated (step S 27 ; YES), the CPU  11  outputs the image processed image to the designated output device (step S 28 ).  
         [0061]    As described above, according to the CPU  11 , the processing parameter adjusted for the gradation characteristic and frequency characteristic of the present output device is stored, this processing parameter is referred to, the processing parameter is calculated corresponding to the gradation characteristic and frequency characteristic of the output device of the output destination, and according the calculated processing parameter, the image is image processed and outputted to the output device. Accordingly, the capacity of the memory to store the processing parameter can be suppressed.  
         [0062]    In this connection, in the above embodiment, when the processing parameter according to the gradation characteristic and frequency characteristic of the present output device is stored and outputted by the other output device which is the output destination, the processing parameter is calculated corresponding to its the gradation characteristic and frequency characteristic, however, the output characteristic (the gradation characteristic and frequency characteristic) of the reference output device which is a certain reference, and the reference processing parameter in the reference output device are stored, and when the image is outputted to the output device having the other output characteristic, the reference processing parameter is referred to, the processing parameter is calculated corresponding to the gradation characteristic and frequency characteristic of the output device of the output destination, and according to the calculated processing parameter, the image processing is conducted and the image may be outputted to the output device designated as the output destination. Thereby, in a plurality of medical image processing apparatus, the default processing parameter or the characteristic information of the output device can be jointly owned, and the wide use property is increased.  
         [0063]    (The third Embodiment)  
         [0064]    The third embodiment in which, when the medical image processing apparatus  1  is used by a plurality of operators, the processing parameter is set for each operator, will be described below. In the present embodiment, the recording medium  15   a  is structured by having the default parameter table  154  in its inside.  
         [0065]    [0065]FIG. 9 is a view showing a data storing example in the default parameter table  154 . As shown in FIG. 9, in each line of the default parameter table  154 , the processing parameter for each photographic part corresponding to the operator (for example, “u1”, “u2”, . . . ) (for example, as the processing parameter corresponding to the operator u 1  and photographic part b 1 , “p11, q11”, and as the processing parameter corresponding to the operator u 1  and photographic part b 2 , “p12, q12”, . . . ), are stored. In each line of the default parameter table  154 , the processing parameter for each operator corresponding to the photographic part (for example, “b1”, “b2”, . . . ) (for example, as the processing parameter corresponding to the photographic part b 1  and operator u 1 , “p11, q11”, and as the processing parameter corresponding to the photographic part b 1  and operator u 2 , “p21, q21”, . . . ), are stored. The processing parameter stored in a position at which the operator line and photographic part line cross each other is the processing parameter set in the default under the assumption that the optimum image processing can be conducted when a plan of the operator is considered, and the image of a certain photographic part is displayed (outputted).  
         [0066]    In this connection, because the other structure of the medical image processing apparatus  1  in the present embodiment is the same as the above-described first embodiment, the same numeric code is attached to each component, and the graphic display of the component and explanation are omitted.  
         [0067]    Referring to a flowchart in FIG. 10, the image output processing C conducted by the medical image processing apparatus  1 , will be described below.  
         [0068]    When the operator (user) is designated by the operation of the muse or touch operation on the image output operation image plane (step S 31 ), the CPU  11  discriminates the operator number of the designated operator, and refers to the medical image information stored in the recording medium  15   a , and discriminates the photographic part of the image which is the output object (step S 32 ). Next, the CPU  11  refers to the default parameter table  154 , and obtains the processing parameter corresponding to the operator number and photographic part discriminated in step S 32  (step S 33 ). For example, when it is discriminated that the operator number is uk and photographic part is bm, from the default parameter table  154  (refer to FIG. 9), the processing parameters pkm and qkm are obtained. Then, the CPU  11  makes the image processing section  17  conduct the image processing on the output object image according to the processing parameter (step S 34 ), and displays the image processed image on the image output operation image plane (step S 35 ).  
         [0069]    After the display of the image processed image onto the image output operation image plane, the change of the processing parameter is designated, and when new parameter is inputted (step S 36 ; YES), the CPU  11  calculates the new processing parameter according to the inputted parameter (step S 37 ), and makes the image processing section conduct the image processing on the output object image according to the calculated processing parameter (step S 38 ), and displays the image processed image on the image output operation image plane (step S 39 ). In step S 40 , until the output button is pressed, the CPU  11  repeatedly conducts the processing of the above steps S 36 -S 40 . Then, when the output button is pressed and the output of the image is designated (step S 40 ; YES), the CPU  11  outputs the image processed image to the output device (step S 41 ).  
         [0070]    After the image is outputted, the CPU judges whether the change of the processing parameter is conducted in step S 36 , and when it is judged that the change of the processing parameter is not conducted (step S 42 ; NO), the image output processing C is completed. When it is judged that the change of the processing parameter is conducted (step S 42 ; YES), the CPU  11  re-rewrites the processing parameter in the default parameter table  154  corresponding to the operator number and photographic part to the processing parameter calculated in step S 37  (step S 43 ), and the image output processing C is completed.  
         [0071]    [0071]FIG. 11 is a view showing an example of the image output operation image plane  132 . As shown in FIG. 11, on the left side of the image plane of the image output operation image plane, the photographic image to be outputted to the other output destination is displayed. On the lower portion of the image plane, the operator direction button such as “operator 1”, “operator 2” and “operator 3” is displayed, and when this operator direction button is pressed, the image processing is conducted on the photographic image with the processing parameter corresponding to the designated operator and the image is displayed, and when the “output” button is pressed, the processed image is outputted to the output device. On the right side of the image plane, the input space of the parameter is displayed. In the step S 36  in FIG. 10, the numerical value is selected from the input area of this parameter, and when “change” button is pressed, in the step S 37 , according to the inputted numerical value, the processing parameter corresponding to the operator designated in the step S 31  and the photographic part of the image is calculated, and re-written in the step S 43 .  
         [0072]    As described above, according to the medical image processing apparatus  1 , when the operator is designated, the CPU  11  refers to the default parameter table  154 , and obtains the processing parameter corresponding to the designated operator and part of the photographic image, and according to the processing parameter, conducts the image processing on the photographic image and outputs it to the output device. Accordingly, even when a plurality of operators use the same output device, when the default processing parameter is stored for each operator, it is not necessary that the desired processing parameter is set again every when the image is outputted by the output device, and the image output operation becomes easy.  
         [0073]    In this connection, the description of the fourth embodiment is a preferred example according to the present invention, and the present invention is not limited to this description.  
         [0074]    For example, in the above embodiment, the operator is specified by pressing the operator direction button from the operation image plane, but it is not limited to this, for example, in the case where the user ID is inputted when the medical image processing apparatus  1  is used, from this user ID, the operator is discriminated, and the image processing may also be conducted with the corresponding processing parameter.  
         [0075]    Further, in the first-third embodiments, the processing parameter and the calculation method of the processing parameter are an example, and are not limited to this.  
         [0076]    Further, the first-third embodiments are separately described, but the function of the first-third embodiments may also be jointly owned. Other then that, relating also to the detailed structure of the medical image processing apparatus  1  and the movement of the detailed portion, they can be appropriately changed within the scope not departed from the spirit of the present invention.  
         [0077]    In the above examples, it is characteristic that mainly two different elements are focused as conditions and used to decide the processing parameters. However, the present invention is possible to be applied to the other configuration in which three different elements are used to decide the processing parameters.  
         [0078]    For example in FIG. 12, the three conditions of operators, output devices and photographic parts are used to decide the processing parameters. In this case, for the same operator U 1 , there are three different types of printers  1  through  3  and three different photographic parts of chest, stomach and legs are provided for the conditions so that the total of nine processing parameters are preset to the apparatus. For this example, the methods to call out the processing parameters from the apparatus and to setting the parameters in the apparatus are assumed to be the same as those of aforementioned examples.  
         [0079]    According to the present invention, the image processing parameter corresponding to each photographic part of the medical image and for each output device to output the processed image is stored in the storing means, and the photographic part of the obtained medical image and the output device of the output destination are discriminated, and the image processing parameter corresponding to the discriminated photographic part and output device are read from the storing means, and according to the read image processing parameter, the image processing is conducted on the obtained medical image and the image is outputted to the output device. Accordingly, in the case of the system in which a plurality of output devices are connected, every when the image is outputted by the output device, it is not necessary that the image processing parameter is set again, and the image output operation becomes easy.  
         [0080]    Further, according to the present invention, together with the image output characteristic of the output device whose output image is already confirmed, the image processing parameter for each photographic part of the medical image corresponding to the output device are stored in the storing means, and when the processed image is outputted to the other output device different from the above-described output device, the image processing parameter stored in the storing means is corrected adjusting to the image output characteristic of the other output device, and according to the corrected image processing parameter, the image processing is conducted on the obtained medical image. Accordingly, in the case of the system in which a plurality of output devices are connected, every when the image is outputted by the output device, it is not necessary that the image processing parameter is set again, and the image output operation becomes easy. Further, the capacity to store the processing parameter can be suppressed.  
         [0081]    According to the present invention, together with the image output characteristic of the standard output device, the standard image processing parameter for each photographic part of the medical image corresponding to the output device are stored in the storing means, and when the processed image is outputted to the output device different from the standard output device, the standard image processing parameter stored in the storing means is corrected adjusting to the image output characteristic of the output device to output it, and according to the corrected image processing parameter, the image processing is conducted on the obtained medial image. Accordingly, in the case of the system in which a plurality of output devices are connected, every when the image is outputted by the output device, it is not necessary that the image processing parameter is set again, and the image output operation becomes easy. Further, the capacity to store the image processing parameter can be suppressed, and in a plurality of medical image processing apparatus, the image processing parameter stored in the storing means or the characteristic information of each output device can be owned jointly.  
         [0082]    According to the present invention, the image processing parameter corresponding to each photographic part of the medical image and for each operator is stored in the storing means, the photographic part of the obtained medical image and operator are discriminated, and the image processing parameter corresponding to the discriminated photographic part and operator is read from the storing means, and according to the read image processing parameter, the image processing is conducted on the obtained medical image, and the image is outputted to the output device. Accordingly, even when a plurality of operators use the same output device, every when the image is outputted by the output device, it is not necessary that the parameter is set again to the image processing parameter matched with the plan, and the image output operation becomes easy.
