A grid is introduced which allows simple estimates of gallbladder size from parallel diameters in ultrasonic images. Depending upon the gallbladder's size between 4 and 20 diameters had to be measured. Deviation from true size did not exceed 4%. --A possible use may be the evaluation of the gallbladder's size before and 30--45 minutes after a defined meal.
引入了一种网格，可根据超声图像中的平行直径对胆囊大小进行简单估算。根据胆囊大小，需要测量4至20条直径。与真实大小的偏差不超过4%。——一种可能的用途是评估特定餐后30至45分钟前后胆囊的大小。
