PROBLEM TO BE SOLVED: To detect a boundary of biological tissue layers of a subject with a high degree of precision.SOLUTION: In an ultrasonic measurement apparatus 1, an ultrasonic measurement part 2 performs ultrasonic measurement to acquire a tomographic image of a subject. A boundary detection part 56 analyzes the tomographic image and detects a boundary of biological tissue layers of the subject. The boundary detection part 56 includes a boundary candidate detection part 561 for detecting a plurality of boundary candidates for the biological tissue layers, and a boundary specification part 563 for calculating an index value using, as a boundary, the boundary candidates based on the tomographic image, and specifying the boundary.COPYRIGHT: (C)2015,JPO&INPIT【課題】被検者の生体組織層の境界を精度よく検出すること。【解決手段】超音波測定装置1において、超音波測定部2は、被検者の断層画像を取得する超音波測定を行う。境界検出部56は、断層画像を解析して被検者の生体組織層の境界を検出する。境界検出部56は、生体組織層の境界候補を複数検出する境界候補検出部561と、断層画像に基づいて境界候補を境界とする指標値を算出して境界を特定する境界特定部563とを有する。【選択図】図5
