Filed: 2003-04-01
Abstract: <P>PROBLEM TO BE SOLVED: To improve an electronic caliper function of an ultrasonograph.  <P>SOLUTION: A caliper image generation section 21 generates a parallel two linear caliper image signal, sends the signal to a monitor device 19 through a video output section 15 and displays a caliper of parallel two lines, superimposed on an ultrasonic B mode image displayed on the screen thereof. When a trackball 18 is operated, an image operating section 22 rotates the parallel two linear calipers displayed on the screen in response thereto and moves parallelly, thereby setting the position of the linear caliper to ensure that they touch the edge of an object to be measured on the B mode image displayed on the screen of the monitor device 19. A distance measuring section 23, computes the actual distance in the object to be examined on the basis of the relationship between the size of the image on the screen of the monitor and the sound velocity of the object to be examined from the clearance of the parallel two linear calipers and displays the actual distance in numerical value at a corner or the like of the monitor screen.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
