PROBLEM TO BE SOLVED: To obtain a feature value correctly indicating a rheology property of biological soft tissues.SOLUTION: A physical property value detection system 10 for the rheology property is provided with a push-in measurement apparatus 12 that pushes in the biological soft tissues with predetermined force and measures the magnitude of the push-in force and a deformation amount of a site of the pushed-in biological soft tissues, and a physical property value calculation apparatus 13 that obtain, by calculation, physical property values on the basis of a result of the measurement by the push-in measurement apparatus 12. The push-in measurement apparatus 12 is configured to be capable of pushing in biological tissues with a plurality of patterns each having different push-in states. The physical property value calculation apparatus 13 is configured to obtain the physical property values on the basis of each of the deformation amounts measured in each push-in state.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】生体軟組織に対してレオロジー特性を的確に表す特徴値を求めること。【解決手段】レオロジー特性の物性値検出システム10は、生体軟組織を所定の力で押し込み、その際の押込力の大きさと押し込まれた生体軟組織の部位の変形量とを測定する押込み測定装置12と、押込み測定装置12での測定結果に基づき演算によって物性値を求める物性値演算装置13と備えている。押込み測定装置12は、押し込み状態の異なる複数パターンで生体軟組織を押し込み可能に設けられており、物性値演算装置13では、各押し込み状態で測定されたそれぞれの変形量に基づき、物性値を求めるようになっている。【選択図】 図1
