Abstract

An image processor comprises a signal processing circuit for subjecting a three-dimensional echo signal transmitted from an ultrasonic 3D probe (1) to a signal processing, a memory for storing at least one set of three-dimensional echo data converted by the signal processing circuit (6), a large capacity recording unit, a control circuit for controlling input / output signals from an input unit, an image processing circuit for performing image processings such as coordinate conversion according to the three-dimensional echo data stored in the memory, a display circuit for displaying the ultrasonic three-dimensional image processed by the image processing circuit, and a CPU for performing arithmetic operation for 'volume measurement'. The tissue of interest can be simply and accurately measured.

Description

technical field [0001] The present invention relates to an ultrasonic image diagnostic apparatus for observing and examining a subject by three-dimensional ultrasonic scanning. Background technique [0002] Conventionally, an ultrasonic imaging diagnostic apparatus is used that inserts an ultrasonic probe having an ultrasonic probe inside a distal end into a body cavity, transmits and receives ultrasonic waves from the ultrasonic probe, and obtains ultrasonic images of living organs for diagnosis. [0003] One of the living organs to be diagnosed is the prostate. In the diagnosis of the prostate, not only its shape but also its volume is an important diagnostic factor. [0004] Therefore, in Japanese Unexamined Patent Publication No. 2001-178725, for example, a method is adopted in which two axes perpendicular to the ultrasonic tomographic image are designated and the volume of the ellipse of revolution is calculated from the axes. [0005] However, in the above-mentioned m...
