Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The assessment video generation method can be applied to the application environment shown in fig. 1. The ultrasound display terminal 102 communicates with the cloud server 104 through a network. A first terminal 106 used by a physician to be examined (typically a primary physician) and a second terminal 108 used by a specialist physician are also in communication with the cloud server 104 via the network. Responding to a video recording instruction through the ultrasonic display terminal 102, starting to acquire a display interface image of the ultrasonic display terminal, and simultaneously starting image acquisition equipment to acquire an operation method of the ultrasonic probe; generating a first temporary file according to the acquired display interface image sequence, and generating a second temporary file according to the acquired operation method image sequence; and when the video recording is finished, combining the first temporary file and the second temporary file to generate an assessment video file corresponding to the ultrasonic scanning skill.
The ultrasonic imaging device includes an ultrasonic probe and an ultrasonic display terminal 102. The ultrasound display terminal 102 includes a processor, a display, and a memory. The processor processes the ultrasound echo signals/data to obtain an ultrasound image of the target site or an ultrasound image of the interventional object. The ultrasound images obtained by the processor may be stored in a memory, displayed on a display, and transmitted to an ultrasound workstation. The first terminal 106 and the second terminal 108 may be, but are not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the cloud server 104 may be implemented by an independent server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a generating method of a review video is provided, which is described by taking the method as an example applied to the ultrasound display terminal 102 in fig. 1, and includes the following steps:
s202, responding to a video recording instruction, starting to acquire a display interface image of the ultrasonic display terminal, and simultaneously starting image acquisition equipment to acquire an operation method of the ultrasonic probe.
When medical ultrasonic detection is carried out, a primary doctor operates an ultrasonic probe to scan a target part to be detected. The ultrasonic display terminal applies an electric signal on the ultrasonic probe through the ultrasonic cable so that the ultrasonic probe sends ultrasonic waves to a target part to be detected. The ultrasonic probe receives an echo signal reflected by the target part and feeds the echo signal back to the ultrasonic display terminal through the ultrasonic cable, and the ultrasonic display terminal can generate an ultrasonic image of the target part according to the echo signal so as to be diagnosed by a doctor. The target site is a site of interest to a physician, such as the liver, pancreas, uterus, etc. When the ultrasonic display terminal runs, a corresponding display interface can be provided for the primary physician to operate, and a control such as an identification selection box or a menu bar can be included in the display interface. The elementary physician can input an operation instruction for the ultrasonic image through the display interface according to the actual use condition so as to measure the ultrasonic imaging through the ultrasonic display terminal. The manipulation of the ultrasonic probe may include advancing, retreating, rotating, tilting to the left, tilting to the right, increasing and decreasing force, increasing and decreasing speed, and the like. The image acquisition equipment can acquire images of the operation methods of the ultrasonic probe by a doctor, so that the operation methods of the ultrasonic probe by the doctor are saved, and a foundation is laid for generating an examination video file.
Specifically, a video recording button is arranged in a display interface of the ultrasonic display terminal, and when a primary doctor conducts scanning exercise or scanning examination on the ultrasonic display terminal, the video recording button is triggered. If the skill level of the primary physician needs to be correctly and fully evaluated, not only the live condition of the display interface of the ultrasound display terminal in the ultrasound scanning process needs to be recorded, but also the operation method of the primary physician on the ultrasound probe needs to be recorded. Therefore, the ultrasonic display terminal responds to the video recording instruction sent by the primary physician, and not only starts to record the screen on the display interface of the ultrasonic display terminal, but also starts the image acquisition equipment to acquire the image of the operation method of the ultrasonic probe. Therefore, the ultrasonic scanning process of the primary physician can be completely saved, 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.
And S204, generating a first temporary file according to the acquired display interface image sequence, and generating a second temporary file according to the acquired operation method image sequence.
Specifically, in the examination process of the ultrasonic scanning skill, a series of display interface images obtained by recording a display interface of the ultrasonic display device form a display interface image sequence. A series of manipulation images acquired by the image acquisition apparatus constitute a manipulation image sequence. In order to simplify the assessment mode and improve the assessment efficiency, the assessment video file is creatively created by utilizing the display interface image sequence and the operation method image sequence, and when the assessment video file is played, the display interface image and the operation method image need to be synchronously played according to the time corresponding relation between the display interface image and the operation method image. Therefore, in order to ensure the accuracy of the data and generate an ordered assessment video file subsequently, the display interface image and the operation method image are respectively temporarily stored. And storing the acquired display interface image sequence in a first temporary file, and storing the acquired operation manipulation image sequence in a second temporary file.
And S206, when the video recording is finished, combining the first temporary file and the second temporary file to generate an assessment video file corresponding to the ultrasonic scanning skill.
Specifically, on one hand, in order to improve the examination efficiency, the first temporary file and the second temporary file are combined to generate a video file, so that the time and the energy of examination work of a specialist are reduced. On the other hand, the accuracy of the assessment video file needs to be ensured, and the synchronous playing of the display interface image picture and the operation technique image picture needs to be ensured, so that the time for stopping acquiring the display interface image needs to be consistent with the time for stopping acquiring the operation technique image. Therefore, at the moment when the video recording is finished, the first temporary file and the second temporary file are combined to generate an assessment video file corresponding to the ultrasonic scanning skill, and the first temporary file and the second temporary file are deleted. The examination video file is provided with a file header, and the file header information comprises data length information of the examination video file.
In the method for generating the assessment video, the display interface image of the ultrasonic display terminal is obtained by responding to the video recording instruction, and the image acquisition equipment is started to acquire the image of the operation method of the ultrasonic probe, so that the two parts of images have the same initial time; generating a first temporary file according to the acquired display interface image sequence, and generating a second temporary file according to the acquired operation method image sequence; when the video recording is finished, combining the first temporary file and the second temporary file to generate an assessment video file corresponding to the ultrasonic scanning skill, and ensuring that the two parts of images have the same finishing time; the synchronous playing of the display interface image picture and the operation method image picture in the assessment video file is realized, so that the ultrasound scanning skill of the primary physician can be assessed by using the assessment video file, the assessment mode of the ultrasound scanning skill in the traditional technology is changed, the scanning process of the primary physician for the on-site examination by a specialist is avoided, and the assessment efficiency of the ultrasound scanning skill is improved.
In one embodiment, as shown in fig. 3, in response to a video recording instruction, starting to acquire a display interface image of an ultrasound display terminal, the method includes the following steps:
s302, responding to a video recording instruction, newly building a window in a display interface of the ultrasonic display terminal, and blocking other areas except the ultrasonic image area in the display interface corresponding to the window;
and S304, acquiring a display interface image corresponding to the window.
The display interface image of the ultrasonic display terminal not only comprises an ultrasonic image area, but also comprises other areas for displaying patient information, doctor information, hospital information and the like. In particular, in order to ensure the fairness of the assessment, it is necessary for the specialist to hide such information of other areas. Therefore, before the video recording is started, namely after the video recording instruction is responded, a window can be newly built in the display interface of the ultrasonic display terminal. In order not to affect the normal functioning of the examined physician, the window may be invisible to the examined physician, that is, the information seen by the examined physician still includes the information of the ultrasound image area and other areas, while the expert physician only needs to see the ultrasound image area, and then the other areas except the ultrasound image area in the display interface corresponding to the newly-built window are blocked, so as to obtain the corresponding display interface image based on the newly-built window.
In this embodiment, through the new creation of the window, and the other areas except the ultrasound image area in the display interface corresponding to the window are blocked, the fairness of the examination is ensured.
In one embodiment, as shown in fig. 4, generating a first temporary file according to the acquired display interface image sequence, and generating a second temporary file according to the acquired manipulation image sequence includes the following steps:
s402, acquiring display interface images at a preset frame rate, and sequentially writing the display interface images into a first temporary file according to a time sequence;
s404, acquiring the operation method images at the same preset frame rate, and sequentially writing the operation method images into a second temporary file according to the time sequence.
Wherein the number of frames of the first temporary file is the same as the number of frames of the second temporary file. Specifically, in order to ensure the accuracy of the assessment video file and the synchronous playing of the display interface image picture and the operation technique image picture, the time for starting to acquire the display interface image and the time for starting to acquire the operation technique image need to be kept consistent, the time for stopping to acquire the display interface image and the time for stopping to acquire the operation technique image need to be kept consistent, and the two images need to be written into the first temporary file and the second temporary file respectively according to the time sequence at the same frame rate (for example, 15 frames per second).
Further, the second temporary file is added to the tail position of the first temporary file, and an assessment video file corresponding to the ultrasonic scanning skill is generated.
In the embodiment, the acquired display interface images and the acquired operation method images are temporarily stored according to the same frame rate and the time sequence, the acquired display interface image sequence is written into the first temporary file, and the acquired operation method image sequence is written into the second temporary file, so that the accuracy of data can be ensured, and an ordered assessment video file can be generated subsequently.
In one embodiment, as shown in fig. 5a, the number of the qualifying video files is plural. The method further comprises the following steps:
s502, responding to a selection instruction of at least one assessment video file, and determining the assessment video file corresponding to the selection instruction as an assessment video file to be uploaded;
s504, responding to the uploading instruction, and uploading the assessment video files to be uploaded to a cloud server.
As shown in fig. 5b, a primary physician may perform multiple operations on the ultrasound display terminal according to exercise requirements or examination requirements to obtain a plurality of examination video files, browse the plurality of examination video files, and determine a satisfactory video file from the plurality of examination video files. Specifically, a plurality of assessment video files are selected, and in response to a selection instruction of at least one assessment video file, the selected at least one assessment video file is determined as an assessment video file with an upload function.
