Description

Method and device for checking ultrasonic contrast image and dynamic image Technical Field The present disclosure relates to a medical imaging apparatus, method, and medium, and more particularly, to a viewing method and viewing device of ultrasound contrast images and dynamic images. Background The ultrasonic wave generation and detection are simple and cheap, can penetrate deep into the tissue without causing tissue injury, and are very suitable for noninvasive biomedical imaging. The ultrasonic waves are scattered when meeting the scatterers, and the scattering strength is related to the size and shape of the scatterers and the acoustic impedance difference of the surrounding tissues. Blood scatters ultrasound weakly, so blood exhibits "anechoic" on common ultrasound instruments. If a medium (microbubbles) with a distinct acoustic impedance from blood is added to the blood, the scattering in the blood is enhanced, which is the fundamental principle of acoustic contrast. By utilizing the principle, the ultrasonic contrast agent, namely the solution containing microbubbles, is injected into the body, and enters organs and tissues to develop and enhance the organs and tissues, thereby providing important basis for clinical diagnosis. In recent years, ultrasound imaging has played an increasingly important role in the differential diagnosis and ablation evaluation of cardiovascular diseases, liver, thyroid, breast and other diseases. Taking liver tumors as an example, micro-blood flow inside malignant tumors tends to be more abundant than normal tissues, and the typical appearance of ultrasound contrast images is that microbubbles in the focal region enter and resolve more rapidly than normal tissues. In general, in order to distinguish such hemodynamic differences between normal tissue and malignant diseased tissue, ultrasound contrast is required to have a certain imaging frame rate. The currently common 2D real-time ultrasound imaging frame rate is typically set to 10-15fps. Recently introduced high frame rate contrast techniques are capable of increasing the contrast imaging frame rate to tens or even hundreds of frames per second. Because of the limited survival time of ultrasound contrast agents in the body, physicians often store all of the contrast image data during this time when performing a contrast examination. The focus data can be reviewed repeatedly, enhancing diagnostic confidence. On the other hand, the device can be used for clinical research, academic lecture development or clinical teaching. But at the time of browsing or playback, there is a problem in that it takes a long time to find a valid information frame when a doctor starts browsing the contrast data frame by frame because of a large number of data frames of high frame rate contrast. Disclosure of Invention Therefore, there is a need for an ultrasound contrast image and a viewing method and a viewing device for moving images, which can help a doctor to significantly improve the viewing efficiency of high-frame-rate moving image data and accurately position the high-frame-rate moving image data on a single image frame or a small-range image frame that the doctor desires to view, and in which the interaction operation required by the doctor is similar to that of the conventional viewing, and which is convenient to operate, high in user friendliness, and capable of saving the time of the doctor and significantly reducing the workload of the doctor. According to a first aspect of the present disclosure, a method of viewing an ultrasound contrast image is provided. The ultrasound contrast image data is image data generated by the ultrasound contrast device in the imaging mode. The imaging mode comprises a first imaging mode and a second imaging mode, the imaging speed in the first imaging mode is faster than the imaging speed in the second imaging mode, the range of a first browsing step length corresponding to the imaging mode is determined based on the imaging speed corresponding to the imaging mode, and the range of the first browsing step length corresponding to the imaging mode is positively correlated with the imaging speed corresponding to the imaging mode. The viewing method comprises the steps of receiving a first operation of setting a first viewing range by a user through an interaction member in a first browsing step length of a plurality of frames under the condition that ultrasonic contrast image data to be viewed are opened for manual viewing by a processor, positioning the ultrasonic contrast image data to a viewing neighborhood containing the first viewing range in response to detection of the first operation, receiving a second operation of performing the second operation on the viewing neighborhood containing the first viewing range by the user through the interaction member in a second browsing step length of a single frame, and determining a current image frame corresponding to the second operation performed by th
