Abstract

A tumor region setting section sets a liver tumor region for a plurality of ultrasonic image data along a time series acquired by ultrasonically capturing a subject to which a contrast agent has been administered. A TIC generator obtains a time change indicating a time change of the pixel values in the liver tumor region based on the plurality of ultrasonic image data along the time series. A peak-detection section specifies a peak point of the time change and obtains the time and pixel value of that peak point. A first determination section determines the degree of malignancy of the liver tumor based on the time and pixel value of the peak point. A display controller displays the degree of malignancy on a display section.

Description

technical field [0001] The present invention relates to a medical image processing device for judging tumors based on ultrasonic images obtained by photographing a subject to which a contrast agent has been administered. In addition, the present invention also relates to an ultrasonic image acquisition device for judging a tumor based on an ultrasonic image. Background technique [0002] "Malignant neoplasm (cancer)", "heart disease" and "cerebrovascular disease (cerebral stroke)" are among the top three causes of death in Japan . In particular, cancer has the largest number of deaths among the three major causes of death, accounting for 30% of the total number of deaths. [0003] When cancer is classified according to the site of occurrence, in Japan, it can be classified into lung cancer, gastric cancer, colon cancer, and liver cancer in descending order of the number of patients . However, the 5-year relative survival rate (relative survival) of patients with gastric ...
