Abstract

The present disclosure relates to a signal processing apparatus and method that make it possible to improve the precision of probe movement amount calculation. A transducer array A is a one-dimensional transducer array that corresponds to a conventional transducer array. A transducer array B and a transducer array C are joined to the two ends (the left and right ends in the figure) of the short-edged sides of the transducer array A so that the arrangement direction of the respective transducers of the transducer array A is orthogonal to the arrangement directions of the respective transducers of the transducer array B and the transducer array C. The present disclosure can be applied, for example, to a signal processing apparatus that generates and displays an ultrasound image from the signal of a probe that captures ultrasound images.

Description

technical field [0001] The present disclosure relates to a signal processing device and method, and more particularly, to a signal processing device and a signal processing method for improving the calculation accuracy of a probe movement amount. Background technique [0002] In ultrasonic diagnostic devices that capture ultrasonic images, detection of probe movement plays an important role in computer-aided diagnosis, measurement of tissue shape and properties, generation of panoramic images, processing of 3D reconstruction, and the like. [0003] Regarding detection of probe movement, for example, Patent Document 1 discloses a method of forming two scanning planes using a two-dimensional probe, and guiding detection of probe movement and reconstruction of three-dimensional movement. [0004] Patent Document 2 discloses a method of forming an ultrasonic probe using one-dimensional array transducers perpendicular to each other, and then tracking the movement of the ultrasoni...
