摘要

Ultrasound diagnostic equipment for diagnosing a region of interest (ROI) of an organ by using a scattering coefficient and an attenuation slope, which comprises a scattering power calculation unit (6) for calculating a scattering spectrum of the region of interest (ROI), a cumulative attenuation slope calculation unit (8) for calculating a cumulative attenuation slope of the intervening tissue between a body surface (BS) and a position (SV1 SV2) of blood close to the region of interest (ROI) by using a scattering coefficient of blood which is previously known, and a scattering coefficient calculation unit (6) for calculating a scattering coefficient calculation unit (6) for calculating a scattering coefficient of the region of interest (ROI) by using the calculated cumulative attenuation slope of the intervening tissue between body surface and the blood close to the region of interest (ROI). Therefore, a scattering coefficient and an attenuation slope of the region of interest (ROI) can be calculated with high accuracy, and the region of interest (ROI) can be exactly diagnosed by the calculated scattering coefficient and the attenuation slope thereof.
