Ultrasonic imaging device and method

Abstract

The invention discloses an ultrasonic imaging device and a method. The ultrasonic imaging device comprises a conventional imaging module, an interesting area confirming module and an optimization imaging module. The conventional imaging module is used for emitting ultrasonic pulses to a goal to be detected, receiving an ultrasonic echo signal reflected by the goal to be detected and outputting a conventional imaging image after conducting signal process on the received ultrasonic echo signal. The interesting area confirming module is used for confirming an interesting area in the conventional imaging image. The optimization imaging module is used for freezing an image area in the conventional imaging image except for the interesting area, conducting optimization imaging process on the interesting area and outputting an interesting area image after the optimization imaging process. Based on the conventional ultrasonic imaging, the interesting area is confirmed, the area expect for the interesting area is kept to be in an image frozen state, only the interesting area is optimized so that each interesting area reaches optimal imaging effect, and therefore the defects of the optimization imaging image are overcome, and diagnosis confidence of a user is increased.

Description

technical field [0001] The invention relates to the field of ultrasonic imaging, in particular to an ultrasonic imaging device and method. Background technique [0002] In the conventional two-dimensional grayscale imaging method, in order to take into account the overall image performance, the ultrasound imaging frequency must meet the entire imaging depth. When the imaging depth is deep (that is, far-field imaging), the imaging frequency must be low enough to obtain sufficient penetration; however, for near-field and mid-field imaging, if still using a lower imaging frequency, the Spatial resolution will suffer. Due to the consideration of the overall image, the existing imaging methods can only be compromised. [0003] Under the same emission parameters (including emission aperture, scanning range, emission waveform, etc.), the image signal-to-noise ratio is proportional to the emission voltage of the ultrasonic probe; when the instantaneous value of the sound pressure ...
