Abstract
Apparatus and method for evaluating a radiograph, such as an X-ray being diagnosed for chiropractic treatment. The apparatus includes a scanner, a monitor, a central processing unit, user interface equipment, a laser printer and a modem. The X-ray is scanned by the scanner that generates a series of binary values for each segment of the X-ray and representing the relative transparency of each segment. The CPU receives the binary values and constructs a bitmap corresponding to the X-ray image for display on the monitor. Then the CPU enables the user to enhance the image on the monitor to assist in extracting information related to the analysis, diagnosis and prognosis of the condition indicated by the features of the X-ray. Enhancements include increasing brightness, contrast, edge detection and histogrammic equalization. The enhanced image can be used to determine relationships among the features by their separation distance and orientation with respect to each other. The apparatus generates reports and stores the image and information extracted therefrom.
