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

摘要

An ultrasonic observation apparatus includes: a region of interest setting unit that is able to set information on a position and a size of a region of interest in a specimen; a focus point calculation unit that calculates a plurality of focus points in the region of interest based on size information of the region of interest set by the region of interest setting unit; a transmitting and receiving unit that performs a transmission-and-reception of an ultrasonic wave which is focused on the focus points calculated by the focus point calculation unit; a frequency analysis unit that calculates a plurality of frequency spectra by analyzing the ultrasonic wave received by the transmitting and receiving unit with reference to the focus points; a feature data extracting unit that extracts feature data of the frequency spectra calculated by the frequency analysis unit by approximating the frequency spectra; and an image processing unit that generates ultrasonic image data having a display mode corresponding to the feature data extracted by the feature data extracting unit.
