Abstract

The invention relates to an elastic imaging method based on focused ultrasound vibration signals. An imaging system for usage comprises a signal generator, an ultrasonic pulse transceiver, a power amplifier, an excitation probe, a tracking probe, a data collecting card, a computer and a motion controller; through the excitation probe, ARF is generated in a focusing region and brings vibration of amedium of the focusing region, then secondary ultrasonic waves are emitted, amplitude value information of the secondary ultrasonic waves is detected, the elastic feature of the medium is estimated,the excitation probe is moved to scan a whole tested object field, and elastic distribution of the medium is reconstructed.

Description

Technical field

[0001] The invention belongs to the technical field of ultrasonic elastography, and relates to a method for detecting the elastic properties of a medium and reconstructing the elastic distribution of the medium by using a secondary ultrasonic signal excited by a focused ultrasonic sound radiation force, in particular to an elastography method based on a focused ultrasonic sound vibration signal. Background technique

[0002] The elastic properties of biological tissues are inherent mechanical properties in organisms. The elastic properties of different parts of the human body (especially diseased tissues) are different. Some pathological phenomena and physiological activities will cause changes in the elastic properties of biological tissues. Therefore, biological tissues carry rich physiological and pathological information. Palpation is one of the most traditional methods for diagnosing the elastic properties of biological tissues. This method is simple and easy...
