Abstract

An ultrasonic elastograph imaging method comprises the following steps: continuously storing B-type image data and RF data corresponding to the B-type image data during the real-time ultrasonic elastograph imaging process; and then performing off-line ultrasonic elastograph imaging according to the stored B-type image data and the RF data so as to generate and display an elastograph image with different generated parameters. In the method, off-line ultrasonic elastograph imaging can be performed according to the stored RF data and the B-type image data under an off-line status; the elastograph image with different generated parameters can be generated and displayed by adjusting the generated parameters of the ultrasonic elastograph image; during the generation process of the off-line ultrasonic elastograph image, the frame number of the RF data is in a one-to-one relationship with that of the B-type image data, so a B-type image can be taken as reference of the elastograph image; and finally the more optimized elastograph images can be obtained according to the RF data and the generated parameters by selecting an image processing algorithm.

Description

technical field

[0001] The invention relates to an imaging method of medical ultrasonic technology, more specifically, to an ultrasonic elastic imaging method. Background technique

[0002] The frequency of ultrasound is high, the wavelength is short, and it can propagate along a straight line like light, making it possible for people to emit ultrasound in a certain direction; at the same time, ultrasound can propagate smoothly in human tissue, and ultrasound encounters different media. Reflected waves will occur at the interface; therefore, ultrasonic imaging technology is widely used in the field of medical imaging diagnosis.

[0003] Among the existing ultrasound imaging techniques, ultrasound elastography is a commonly used ultrasound imaging technique. The basic principle of ultrasound elastography is: embed the ultrasound probe in a squeeze plate, compress the tissue along the longitudinal direction of the probe, and collect the radio frequency signals before and afte...
