Abstract: [Object] The invention is intended to provide a medical image processing apparatus in which improvement of accuracy of boundary detection of a heart is achieved. [Solving Means] A medical image processing apparatus acquires volume data of a heat, detects a three-dimensional left ventricle coordinate system composed of three axes including at least a left ventricle long axis of the heart from the volume data; uses a boundary model expressed in the left ventricle coordinate system and detects a left ventricle boundary from the volume data, and displays a cross-sectional image orthogonal to at least one axis of the three axes of the left ventricle coordinate system together with the detected left ventricle boundary on the cross-sectional image.

Abstract: An ultrasonic observation apparatus includes: a region of interest setting unit capable of setting information on a region of interest; a focus point calculation unit that divides the region of interest into a plurality of partial regions of interest according to the number of focus points in the region of interest, calculates a focus point in each of the partial regions of interest, and determines a transmission timing according to calculation results; a transmitting and receiving unit that performs a transmission-and-reception of an ultrasonic wave which is focused on the focus point; a frequency analysis unit that calculates a plurality of frequency spectra by analyzing the received ultrasonic wave with reference to the focus point; a feature data extracting unit that approximates the frequency spectra to extract feature data thereof; and an image processing unit that generates ultrasonic image data having a display mode corresponding to the feature data.
