Patent ID: 8519998

Claim:
An ultrasonic imaging apparatus comprising: a transmitter/receiver configured to transmit and receive ultrasonic waves to and from a desired region of a subject via an ultrasonic probe; a signal processor configured to obtain a plurality of physical quantities including at least two of rate, power value, and dispersion of a blood flow, from signals outputted by the transmitter/receiver having received ultrasonic echoes from the subject for a particular voxel, the voxel being assigned to a three-dimensional coordinate position; a voxel-value generator configured to generate a voxel value, which is arranged as a vector containing a plurality of values, corresponds to the respective voxel, and contains the plurality of physical quantities obtained by the signal processor as the values for the voxel value; an image generator configured to sequentially execute a rendering process based on the voxel value by using the plurality of physical quantities contained in the voxel value to generate a three-dimensional image; and a display controller configured to control a display to display the generated three-dimensional image, wherein two physical quantities of the plurality of physical quantities are selected and a threshold and opacity are set for each of the two physical quantities, and wherein after the threshold and the opacity are set, a weighting for the two physical quantities is set and a map-table, that corresponds to the threshold and the opacity, is created.
