Abstract:
A display grayscale curve correction system and method for a mammary gland molybdenum target image. The system comprises a key module, an ARM module, an upper computer, an FPGA module connected to both outputs of the ARM module and the upper computer, and a display panel connected to an output of the FPGA module, wherein the upper computer firstly captures a currently displayed mammary gland image, subsequently analyses an image feature, and then calculates an optimized grayscale correction curve; in addition, the ARM module writes the grayscale correction curve into the FPGA module by means of a serial communication protocol; and the FPGA module performs grayscale mapping on a pixel value of an input image twice, and performs enhanced display on the mammary gland molybdenum target image. In comparison with a common DICOM correction curve, by including a feature of a mammary gland molybdenum target x-ray image into the scope of consideration of optimization, a part where a focus possibly exists can be better highlighted, and the operation is simple and does not occupy resources of an upper computer, and smooth running is guaranteed.

Claim (Index 9):
The display grayscale curve correction method as claimed in  claim 6 , wherein in Step S2, the upper computer captures the current breast mammography X-ray images, and performs feature analysis based on the target image grayscale histogram, expressed as:\n y=f ( x ),(0\u2264 x\u2264 2 b \u22121, x\u03f5Z ) b represents the grayscale bits of the display (display data width), Z represents collection of positive integers, and two feature points will be extracted from this grayscale histogram:\n P 0 ( x 0 ,0) and  P 1 ( x 1 ,2 b \u22121) \n x 0  is the maximum positive integer satisfying f(x 0 )<kT 1  which represents the boundary point of skin tissue and breast tissue, wherein T 1  is defined to be the minimum value of y; x 1  is the maximum integer satisfying \u222b x 1 2 b \u22121 f(x)>T 2  which represents the boundary point of the maximum grayscale pixels in the screen, wherein T 2  is defined as the percentage of the total number of pixels in the screen; the upper computer then calculates the coordinates of P 2 , P 3  and P 4  based on the coordinates of P 0  and P 1 , P 2 , P 3  and P 4  come from the statistics of the grayscale curves of a large number of breast mammography images, which contains the common features of breast images.
