Ultrasonic imaging method and equipment

Abstract

The invention discloses ultrasonic imaging equipment and method, and the method comprises the steps: employing the same ultrasonic probe, and enabling an ultrasonic energy coverage range corresponding to an ultrasonic beam transmitted each time and an ultrasonic echo received each time to comprise a target region of a to-be-scanned target which a user wants to observe; echo signals used for calculating the two-dimensional image, the blood flow image and the instantaneous elasticity detection result all come from the same scanning sequence, so that an additional emission process does not need to be introduced, and the obtained two-dimensional image and the blood flow image can serve as synchronous positioning reference of instantaneous elasticity detection. In addition, synchronous two-dimensional images and blood flow images can be used for assisting in observing whether various change conditions such as displacement and motion interference exist in the instantaneous elasticity collecting process or not.

Description

technical field [0001] The present application relates to the field of medical ultrasound imaging, in particular to an ultrasound imaging method and corresponding ultrasound imaging equipment. Background technique [0002] Ultrasound elastography is one of the hotspots of clinical research in recent years. It mainly reflects the elasticity and hardness of tissues by imaging the elasticity-related parameters in the region of interest, so that it can be used in the auxiliary detection of tissue cancer lesions, benign Malignant discrimination and prognosis recovery evaluation have been more and more applied. Many different elastography methods have been developed, such as quasi-static elastography based on the strain caused by the pressing of the probe on the tissue, shear wave elastography or elastography based on the generation of shear waves by the force of acoustic radiation, and based on the generation of shear waves by external vibrations. Transient elastography, etc. A...

Problems solved by technology

[0003] However, the conventional instantaneous imaging system can only provide one-dimensional information of the local tissue area because the probe has only one array element, and cannot provide two-dimensional images of the tissue, so it cannot be guaranteed that the obtained information comes from the correct target tissue

Even some improved transient elasticity systems can provide tissue two-dimensional images as a reference through conventional ultrasound imaging methods before elastic testing, but because the two-dimensional images are not acquired by the same ultrasound probe as the instantaneous elasticity results, or are not close enough Acquired within a certain period of time, so it is impossible to accurately guide the detection process of instantaneous elasticity

If the position moves or motion interference occurs during the instantaneous elastic detection process, it may cause the detection target to be wrong or the detection quality is not high, resulting in detection failure, etc.
