Abstract: A transmission reception unit forms a transmission beam by outputting a transmission signal to each of a plurality of vibrating elements provided in a probe and further forms a reception beam on the basis of a plurality of wave reception signals obtained from the plurality of vibrating elements. Thus, an ultrasonic beam (transmission beam and reception beam) is scanned in a scan surface. A velocity vector computation unit forms a two-dimensional velocity vector distribution in the scan surface from information regarding velocity of blood flow in an ultrasonic beam direction. A vortex detection unit tracks a flow of a fluid on the basis of the two-dimensional velocity vector distribution obtained by the velocity vector computation unit and detects a vortex in the fluid on the basis of whether or not the flow of the fluid satisfies a recurrence condition.

Abstract: In the present invention, a reference frame selection unit selects a reference frame from among a sequence of frames showing the heart of a fetus. A candidate region group setting unit sets a candidate region group for each of the frames that constitute the sequence of frames. A correlation value calculation unit calculates, for each candidate region, a correlation value between the reference frame and all the other frames. Due to this, a plurality of correlation value waveforms corresponding to the plurality of candidate regions is generated. A stabilized waveform portion specification unit specifies a stabilized waveform portion for each correlation value waveform. A stabilized region specification unit specifies, from among the plurality of stabilized waveform portions, the stabilized waveform portion having the highest degree of stabilization (in other words, the candidate region having the highest degree of stabilization).

A Doppler processing unit generates Doppler information for the body interior on the basis of the receiving signals of ultrasonic waves. A velocity vector calculating unit generates velocity information (velocity vector) for blood flow on the basis of the Doppler information for the body interior. A region of interest setting unit sets a region of interest corresponding to a heart cavity in the image data. An energy calculating unit calculates the amount of energy lost in the blood flow in the heart cavity on the basis of the blood flow velocity information in the region of interest corresponding to the heart cavity.

Abstract: A ROM stores density conversion tables appropriate for a present apparatus to execute recording and standard density conversion tables. As a command is entered on a control panel, a CPU sets the optimum density conversion table in a RAM and again converts image data of 256 levels of gradation for a density adjustment. Resultant image data undergoes false halftone processing in an error diffusion circuit and is transmitted to the present apparatus or a destination recorder. When the record characteristic of the destination recorder is unknown, the standard density conversion table is used, so that no large difference occurs for recording.
