ULTRASOUND OBSERVATION DEVICE, OPERATION METHOD FOR ULTRASOUND OBSERVATION DEVICE, AND OPERATION PROGRAM FOR ULTRASOUND OBSERVATION DEVICE

摘要

An ultrasound observation device including: a region-of-interest setting unit capable of setting the information pertaining to the position and size of a region of interest in a sample; a focus point calculation unit for calculating a plurality of focus points in the region of interest based on the size information of the region of interest set by the region-of-interest setting unit; a transmission/reception unit for carrying out transmission/reception of ultrasonic waves by focusing on the focus point calculated by the focus point calculation unit; a frequency analysis unit for calculating a plurality of frequency spectra by analyzing the ultrasound waves received by the transmission/reception unit with the focus points as a reference; a feature value extraction unit for extracting a feature value of a frequency spectrum by approximating the frequency spectrum calculated by the frequency analysis unit; and an image processing unit for generating ultrasound image data having a display mode corresponding to the feature value extracted by the feature value extraction unit.
