The medical imaging apparatus of the present invention includes a bath tank for accommodating a test subject, the test subject being at least a portion of a body of a human subject; a measurement device movable in a predetermined direction, the measurement device including ab group of elements to emit a radiation wave into the bath tank and receive a scattered radiation wave; and a control unit for measuring by the measurement device when at least one of a location of the test subject within a plane orthogonal to the predetermined direction, a location of the test subject in the predetermined direction, and continuity of data measured by the measurement device satisfies a predetermined condition. Because of this configuration, the medical imaging apparatus is able to acquire data covering the entire measurement target site.

An image analyzer unit performs lesion site detection for each tomographic image. In response to a lesion site detection state, the image analyzer unit outputs a position data array and a size data array that represent temporal change in position and size of the lesion site. A rate of change calculator unit calculates a rate of change that represents a degree of temporal change in tomographic image content. A smoother unit smooths the position data array and the size data array in accordance with the rate of change. A mark is generated based on the smoothed position data array and the smoothed size data array.

For shear wave imaging with ultrasound, the apparent pulse repetition frequency is increased by combining displacements from different lateral locations. Different combinations based on different shear wave velocities and corresponding time shifts and/or attenuations and corresponding scalings are tested to find a smooth displacement profile for the combination. Once the smooth displacement profile is found, the corresponding shear wave velocity is estimated or determined.

A device is for estimating a blood pressure of a user by a combination of an acoustic mode employing acoustic emitters and acoustic detectors and an optical mode using light sources and photodetectors forming source—detector pairs. The device includes an acoustic selection unit to determine the pertinent acoustic emitter—acoustic detector pair as well as an optical selection unit to determine the pertinent light source—photodetector pairs.
