METHOD OF AUTOMATICALLY DETERMINING IMAGED BODY POSTURE IN MEDICAL IMAGE DISPLAY

摘要

A distribution of an image signal read from a stimulable phosphor sheet and bearing a transmitted radiation image of a human body is determined along a horizontal direction acorss the image. Signal values of the distribution along the direction are accumulated, and the rate of change of the accumulated values is determined to find the imaged posture of the image. Alternatively, the separation or the average value of the distribution is determined , or the pattern of the distribution is compared with a plurality of reference signal distribution patterns. The derivative of second order of a function approximated by the distribution pattern may be checked for its sign, or the distribution pattern may be checked to determine whether it is of a one-valley form or a two-valley form.
