It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
The invention aims to overcome the defects of the prior art and provides a method and a system for rapidly entering a movie playback state for ultrasonic diagnosis.
Example one
The embodiment provides a method for rapidly entering a movie playback state for ultrasonic diagnosis, which comprises the following steps:
s1, storing data required in a scanning process in a storage medium;
s2, judging whether information that a user selects to review historical data is received, if so, executing a step S3;
s3, generating an index table of all frame data stored in a storage medium;
s4, entering a movie playback state, playing to a certain frame by adopting a movie player, acquiring image data of the frame based on the index table, and reading the image data of the frame into a storage medium;
s5, processing the image data of the frame by adopting an image algorithm to generate data required by display;
s6, releasing the memory occupied by the frame image data in the storage medium, and displaying the frame image.
In step S1, data required during the scanning is stored in the storage medium.
As shown in fig. 2, which is an exemplary diagram of a data structure, in a scanning process, required data is stored in a storage medium, including a data header and frame data; wherein the data head comprises a total frame number, the size of each frame and the size of the data head; the frame data includes image data, frame number, time stamp, and the like.
In step S3, an index table of all frame data stored in the storage medium is generated. The method specifically comprises the following steps:
s31, reading a data head;
and S32, generating an index table according to the read data header, wherein the information in the index table comprises a frame number, a timestamp, image data and the offset of the current frame relative to the movie data.
Such as the data structure diagram shown in fig. 3.
The method specifically comprises the following steps:
s321, calculating the offset of the current frame relative to the movie data;
assuming that the number of frames ahead of the frame is K, the offset is K × data frame size + data header size (K is equal to or greater than 0).
S322, searching a frame with the frame number N according to the calculated offset, and reading the frame number and the timestamp of the Nth frame data;
s323, adding the read index information of the Nth frame into an index table;
s324, traversing all frames according to the total frame number in the data head, and generating an index table of all frame data according to the steps S321-S323
In step S4, a movie playback state is entered, a movie player is used to play to a frame, image data for the frame is obtained based on the index table, and the frame image data is read into the storage medium. The method specifically comprises the following steps: and the movie player plays the frame with the frame number N, finds the offset of the Nth frame according to the index table, acquires the image data of the Nth frame and reads the image data of the Nth frame into the storage medium.
In step S5, the image data of the frame is processed by an image algorithm to generate data necessary for display.
Processing the frame of image data through DSC and other image algorithms to generate data required by display
In this embodiment, since only a certain frame of image is played back at a certain time during playback of the movie, when the user selects to review the history check, the user first reads a data header in the storage medium, where the size, the number of frames, and the frame number of the movie data are recorded, traverses a fast index table of generated image data, for example, there are 3 frames of data in the storage medium, the generated index table has three pieces of data, where the size, the frame number, the timestamp, and the offset of the frame with respect to the movie data are recorded, instead of loading all image data into a movie playback storage area, when a certain frame is played back, the frame number of the frame is N, we can find the offset corresponding to the frame number N in the index table as M, and if the storage medium is a hard disk, read data with the length of the frame with respect to the start position of the file into the memory, the image data of the frame can be acquired, and after the image data is processed by image algorithms such as DSC and the like, the displayed pixel data is generated and then displayed on the display equipment, namely, the playback of the frame is completed. Therefore, all image data do not need to be loaded into the memory before the movie playback, and only the required data need to be dynamically loaded according to the playing position of the movie player.
The embodiment accelerates the state of entering the movie playback and reduces the resource consumption of the playback storage area by establishing the image data fast index table.
