Title:
ULTRASONIC DIAGNOSTIC APPARATUS
Document Type and Number:
Japanese Patent JP3204722
Kind Code:
B2
Abstract:
PURPOSE: To facilitate the judgment of normality or abnormality in the growth of an embryo by displaying values of deviation rate at several representative parts in comparison on a deviation rate axis the same scale to indicate the upper and lower limits in the normal growth range by two straight lines.
CONSTITUTION: A deviation rate axis display control section 9 displays N deviation rate axes corresponding to N types of representative parts and one origin line passing through origins thereof on a display device 13. A normal limit line display control section 10 displays two straight lines indicating the upper and lover limits given by &verbar IiSk≤α on the N deviation rate axes Ii on the display device 13. A normal limit value memory 11 stores a normal limit value α. αcan be inputted from a keyboard and is variable. A deviation rate plotting control section 12 picks up a deviation rate from the deviation rate memory 8 to plot and display it on the deviation rate axes of the display section 13. Thus, a plurality of values of deviation rate in the growth diagnosing method of embryos can be compared at a quick glance.
