Abstract

The embodiment of the invention provides a correction method for plane ultrasonic transcraniocerebral imaging, which compensates and corrects ultrasonic distortion caused by a skull by utilizing a skull acoustic parameter model and combining an ultrasonic plane wave imaging method, so that an imaging result can be accurately positioned, artifacts caused by the skull are reduced. And a basic imaging technology is provided for craniocerebral ultrasonic imaging equipment.

Description

technical field [0001] The present invention relates to ultrasonic imaging technology, and more specifically, the present invention relates to a correction method for planar ultrasonic transcranial imaging. Background technique [0002] With the development of transducer technology, plane wave imaging technology has made considerable progress, and has been gradually applied to clinical medicine, mostly on the human abdomen. Planar ultrasound imaging has an ultra-high frame rate, which is very suitable for imaging sensitive parts of the brain. However, due to the differences between the skull and the brain tissue in terms of shape, structure, and elastic parameters, its existence greatly hinders the imaging process. Relevant researchers have also made many efforts to reduce the impact of the skull. [0003] The traditional method of brain ultrasound imaging is to remove part of the skull during surgery and directly use conventional ultrasound imaging equipment for explorati...
