detailed description

In order to make the purpose, technical solutions, and advantages of this application clearer, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not used to limit the present application.

The method for generating assessment videos provided in this application can be applied to the application environment as shown in FIG. 1. Wherein, the ultrasound display terminal 102 communicates with the cloud server 104 through the network. The first terminal 106 used by the physician to be assessed (usually a junior physician) and the second terminal 108 used by the expert physician also communicate with the cloud server 104 via the network. The ultrasonic display terminal 102 responds to the video recording instruction to start acquiring the display interface image of the ultrasonic display terminal, and at the same time, the image acquisition device is turned on to perform image acquisition of the operating method of the ultrasonic probe; thus, the first temporary file is generated according to the acquired display interface image sequence , Generate a second temporary file according to the collected operation technique image sequence; when the video recording ends, merge the first temporary file with the second temporary file to generate an assessment video file corresponding to the ultrasound scanning skills.

Among them, the ultrasound imaging equipment includes an ultrasound probe and an ultrasound display terminal 102. The ultrasound display terminal 102 includes a processor, a display, and a memory. The processor processes the ultrasonic echo signal/data to obtain the ultrasonic image of the target part or the ultrasonic image of the interventional object. The ultrasound images obtained by the processor can be stored in the memory, and these ultrasound images can be displayed on the display or sent to the ultrasound workstation. The first terminal 106 and the second terminal 108 can be, but are not limited to, various personal computers, laptops, smart phones, tablets, and portable wearable devices. The cloud server 104 can be an independent server or a server cluster composed of multiple servers. to realise.

In one embodiment, as shown in FIG. 2, a method for generating an assessment video is provided. Taking the method applied to the ultrasound display terminal 102 in FIG. 1 as an example for description, the method includes the following steps:

S202. In response to the video recording instruction, start to acquire the display interface image of the ultrasonic display terminal, and at the same time, turn on the image acquisition device to perform image acquisition on the operating method of the ultrasonic probe.

Among them, when performing medical ultrasound testing, the primary physician operates the ultrasound probe to scan the target site to be tested. The ultrasonic display terminal applies an electrical signal to the ultrasonic probe through the ultrasonic cable so that the ultrasonic probe emits ultrasonic waves to the target site to be detected. The ultrasonic probe receives the echo signal reflected by the target part and feeds the echo signal back to the ultrasonic display terminal through the ultrasonic cable. The ultrasonic display terminal can generate an ultrasonic image of the target part according to the echo signal for diagnosis by the physician. The target part is a part of interest of the physician, such as liver, pancreas, uterus, etc. When the ultrasound display terminal is running, a corresponding display interface can be provided for primary physicians to operate. The above display interface can include controls such as a logo marquee or a menu bar. The junior doctor can input the operation instructions for the ultrasound image through the display interface according to the actual use situation, so as to perform operations such as measurement of the ultrasound image through the ultrasound display terminal. The operating methods of the ultrasound probe may include forward, backward, rotating, tilting to the left, tilting to the right, increasing or decreasing the force, acceleration and deceleration, etc. of the ultrasound probe. The image acquisition device can collect the image of the doctor's operation method of the ultrasound probe, thereby saving his operation method of the ultrasound probe, and lay the foundation for generating the assessment video file.

Specifically, a video recording button is set in the display interface of the ultrasound display terminal, and the video recording button is triggered when the junior physician performs scanning exercises or scanning examinations on the ultrasound display terminal. To make a correct and full assessment of the skill level of junior physicians, it is not only necessary to record the live status of the ultrasound display terminal display interface during the ultrasound scanning process, but also to record the operation techniques of the junior physician on the ultrasound probe. Therefore, the ultrasound display terminal responds to the video recording instruction issued by the primary physician, and not only starts to record the screen of the display interface of the ultrasound display terminal, but also turns on the image acquisition device to perform image acquisition on the operating method of the ultrasound probe. In this way, the ultrasound scanning process of the primary physician can be completely preserved, so that the expert physician can subsequently evaluate the skill level of the primary physician. It should be noted that the shooting range of the image acquisition device may include the operation technique of the ultrasound probe, and may also include the face of the primary physician, so as to avoid the occurrence of cheating.

S204: Generate a first temporary file according to the acquired image sequence of the display interface, and generate a second temporary file according to the acquired image sequence of the manipulation technique.

Specifically, during the assessment process of the ultrasound scanning skills, a series of display interface images obtained by recording the display interface of the ultrasound display device constitute a display interface image sequence. A series of manipulation images collected by the image capture device constitutes a sequence of manipulation images. In order to simplify the evaluation method and improve the evaluation efficiency, this application creatively uses the display interface image sequence and the operation technique image sequence to create the evaluation video file, and when playing the evaluation video file, it is necessary to ensure that the time correspondence between the display interface image and the operation technique image is followed Relationship, the two will be played synchronously. Therefore, in order to ensure the accuracy of the data and the subsequent generation of an orderly assessment video file, the display interface image and the operation technique image are respectively temporarily saved. The acquired image sequence of the display interface is saved in the first temporary file, and the acquired operation technique image sequence is saved in the second temporary file.

S206: When the video recording ends, the first temporary file and the second temporary file are merged to generate an assessment video file corresponding to the ultrasound scanning skill.

Specifically, on the one hand, in order to improve the evaluation efficiency, the first temporary file and the second temporary file are merged to generate a video file, which reduces the time and effort spent on the evaluation of expert physicians. On the other hand, it is necessary to ensure the accuracy of the assessment video file and the synchronized playback of the display interface image screen and the operation technique image screen, so that the time to stop acquiring the display interface image and the time to stop collecting the operation technique image must be consistent. Therefore, at the end of the video recording, the first temporary file and the second temporary file are merged to generate an assessment video file corresponding to the ultrasonic scanning skills, and the first temporary file and the second temporary file are deleted. Among them, the assessment video file is provided with a file header, and the file header information includes the data length information of the assessment video file.

In the above-mentioned method for generating the assessment video, by responding to the video recording instruction, starting to acquire the display interface image of the ultrasonic display terminal, and simultaneously turning on the image acquisition device to collect the image of the operation method of the ultrasonic probe, ensuring that the two parts of the image have the same effect. The first time; and generate a first temporary file according to the acquired image sequence of the display interface, and generate a second temporary file according to the acquired operation technique image sequence; when the video recording ends, the first temporary file and the second temporary file are merged to generate ultrasound The assessment video file corresponding to the scanning skill ensures that the two parts of the image have the same end time; the synchronization of the display interface image screen and the operation method image screen in the assessment video file is realized, so that the assessment video file can be used for the ultrasound of the junior physician The assessment of scanning skills has changed the assessment method of ultrasonic scanning skills in traditional technology, avoiding expert physicians from viewing the scanning process of junior physicians on site, and improving the assessment efficiency of ultrasonic scanning skills.
