Fig. 2 is a diagram illustrating a first process of an image obtaining method according to an embodiment of the present invention. The image acquisition method shown in fig. 2 is applied to an image stitching workflow of a medical device (e.g., a DR device).
As shown in fig. 2, in the present embodiment, the image acquisition method is applied to a medical device (e.g. a digital radiography DR device) including a flat panel detector, and the method may include the following steps:
s201, after the flat panel detector collects image data each time, detecting whether the interval time between the current time and the time when the image data is collected is up to a specified time length, wherein the specified time length is greater than or equal to the waiting time length of the flat panel detector and is less than the processing time length of the collected image data.
For example, after the flat panel detector collects the image data for the first time, it is detected whether the interval time from the current time to the time when the collection of the image data for the first time is completed reaches a specified time length.
And S202, if the interval time reaches the specified duration, starting the next image data acquisition of the flat panel detector.
And S203, processing the acquired image data to obtain an image to be spliced when the flat panel detector finishes acquiring the image data each time.
And S204, when all the images to be spliced which need to be spliced at this time are obtained, splicing all the images to be spliced to obtain spliced images.
Wherein the waiting time may be equal to the sum of the rest time of the flat panel detector and the exposure preparation time.
The rest duration of the flat panel detector is determined by the parameters of the flat panel detector, and can be obtained through the related parameters of the flat panel detector.
The exposure preparation time is also determined by the parameters of the flat panel detector, and can be obtained by the related parameters of the flat panel detector.
The specified time length can be set and modified through setting parameters, but the condition that the specified time length is greater than or equal to the waiting time length of the flat panel detector and is less than the processing time length of the acquired image data is required to be met.
Through S201 and S202, after the flat panel detector collects image data each time, if the interval time from the time when the image data collection is completed reaches a specified time, the flat panel detector is started, so that the flat panel detector immediately performs the next image data collection. Because the specified time length is less than the processing time length of the image data acquired at this time, the starting time of the flat panel detector for acquiring the next image data is earlier than the processing ending time of the image data acquired at this time, and on this basis, the ending time of the flat panel detector for acquiring the next image data is earlier than the scheme that the image data acquisition and the image data processing are performed in series in the background technology, so that the time of the whole image acquisition process is shortened, and the processing efficiency is improved.
From another perspective, it is understood that, since the start time of the next image data acquisition by the flat panel detector is earlier than the processing end time of the image data acquired this time, a part of the acquisition flow of the next image data acquisition is performed in parallel with the processing flow of the image data acquired this time, thereby saving time, shortening the time of the whole image acquisition process, and further improving the processing efficiency.
Through the step S203, the DR apparatus can immediately process the acquired image data after acquiring the image data each time, so that the time of the whole image acquisition process can be shortened as much as possible, and the work efficiency can be improved.
Through step S204, when all the images to be stitched are obtained, stitching processing is performed to obtain a stitched image. Although the stitching process is a part of the whole image acquiring process, step S204 does not shorten the time of the stitching process, that is, the time of the stitching process in the embodiment shown in fig. 1 is the same as that of the stitching process in the prior art, because the time of the stitching process in the image data collecting and image data processing links is shortened in the embodiment shown in fig. 1, the whole image acquiring process time of the embodiment shown in fig. 1 is reduced, and accordingly, the processing efficiency is improved.
The image acquisition method of the embodiments of the present invention is further described below by way of illustration and example.
Fig. 3 is an exemplary diagram of an image data acquisition process and an image data processing process of the flat panel DR apparatus in the process of acquiring the stitched image according to the embodiment of the present invention. As shown in fig. 3, in the present example, as in the background art, it is still assumed that the entire image data of the detection target needs to be acquired in three times, which are image data a1, image data a2, and image data A3, respectively, and that the time required for acquisition and the time required for processing of the respective image data are the same as those in the background art.
As shown in fig. 3, in this embodiment, the splicing workflow of the flat panel DR device is as follows: after exposure preparation is completed, firstly acquiring image data A1, processing the image data A1 after the acquisition of the image data A1 is completed, and in the process of processing the image data A1, resting the flat plate and carrying out next exposure preparation; after the plate rest and exposure preparation is finished, acquiring image data A2, processing the image data A2 after the image data A2 is acquired, and in the process of processing the image data A2, the plate is rested and the next exposure preparation is carried out; after the plate rest and exposure preparation is completed, the image data A3 is acquired, and after the acquisition of the image data A3 is completed, the image data A3 is processed. Thus, images corresponding to the image data a1, the image data a2, and the image data A3 are obtained, and finally, an image corresponding to the image data a1, an image corresponding to the image data a2, and an image corresponding to the image data A3 are stitched (not shown in fig. 3), so that a stitched image can be obtained.
Although the image stitching process is not shown in fig. 1 and fig. 3, the image stitching process is required after all the image data acquisition and processing are finished in the whole process of obtaining the stitched image. Fig. 1 and 3 are only for comparison convenience, and the image stitching process is omitted.
Fig. 4 is a diagram comparing the process shown in fig. 1 with the process shown in fig. 3. Referring to fig. 4, the process shown in fig. 3 is shown above the horizontal dashed line and the process shown in fig. 1 is shown below. The process shown in fig. 3 saves time t (shown by the two vertical dashed lines in fig. 4) compared to the process shown in fig. 1.
As can be seen from fig. 4, in the process of acquiring the stitched image, the embodiment of the present invention saves some time in each image data acquisition and processing process. Therefore, in the process of acquiring the stitched image, the more the acquisition times are, the more the time is saved, the more the time is consumed in the whole process of acquiring the stitched image, and accordingly, the higher the processing efficiency is.
It should be noted that, since the rest duration and the exposure preparation duration of the flat panel detector occupy a part of the time of the whole process of acquiring the stitched image, when the rest duration and/or the exposure preparation duration of the flat panel detector are shortened, the time of the whole process of acquiring the stitched image is shorter, and accordingly, the processing efficiency is higher.
In the embodiment shown in fig. 1, when the stitched image is acquired through the flat panel DR, after a specified time period elapses from the time of acquiring the image data each time, the next image data acquisition is immediately performed, so that the next image data acquisition and the processing of the acquired image data are performed in parallel, the time of the whole process of acquiring the stitched image is shortened, and the processing efficiency is improved.
Fig. 5 is a diagram illustrating a second flow of an image obtaining method according to an embodiment of the present invention. As shown in fig. 5, in the present embodiment, the image acquisition method is applied to a medical device (e.g. a digital radiography DR device) including a flat panel detector, and the method may include the following steps:
s501, after the flat panel detector collects image data each time, whether the interval time between the current time and the time when the image data is collected is up to a specified time length is detected, wherein the specified time length is greater than or equal to the waiting time length of the flat panel detector and is less than the processing time length of the collected image data.
And S502, if the interval time reaches the specified duration, starting the next image data acquisition of the flat panel detector.
And S503, processing the acquired image data to obtain the image to be spliced when the flat panel detector finishes acquiring the image data each time.
And S504, displaying and storing the images to be spliced.
And S505, when all the images to be spliced which need to be spliced at this time are obtained, splicing all the images to be spliced to obtain spliced images.
In the embodiment shown in fig. 5, after the acquired image data is processed to obtain the image to be stitched, the image to be stitched is displayed and stored, so that on one hand, a user can timely know the progress of the process of obtaining the stitched image, and on the other hand, the user can obtain the image to be stitched from the storage position of the image to be stitched when the user needs the image to be stitched.
Fig. 6 is a diagram illustrating a third flow of an image obtaining method according to an embodiment of the present invention. As shown in fig. 6, in the present embodiment, the image acquisition method is applied to a medical device (e.g., a digital radiography DR device) including a flat panel detector, and the method may include the following steps:
s601, after the flat panel detector collects image data each time, detecting whether the interval time between the current time and the time when the image data is collected is up to a specified time length, wherein the specified time length is greater than or equal to the waiting time length of the flat panel detector and is less than the processing time length of the collected image data.
And S602, if the interval time reaches the specified duration, starting the next image data acquisition of the flat panel detector.
And S603, processing the acquired image data to obtain an image to be spliced when the acquisition of the image data by the flat panel detector is finished each time.
And S604, when all the images to be spliced which need to be spliced at this time are obtained, splicing all the images to be spliced to obtain spliced images.
And S605, displaying the spliced image.
In the embodiment shown in fig. 6, after all the images to be stitched are stitched to obtain the stitched image, the stitched image is displayed, so that the user can know the information of the stitched image in time.
Fig. 7 is a diagram illustrating a fourth flowchart of an image obtaining method according to an embodiment of the present invention. As shown in fig. 7, in the present embodiment, the image acquisition method is applied to a medical device (e.g., a digital radiography DR device) including a flat panel detector, and the method may include the following steps:
s701, after the flat panel detector collects image data each time, detecting whether the interval time between the current time and the time when the image data is collected is up to a specified time length, wherein the specified time length is greater than or equal to the waiting time length of the flat panel detector and is less than the processing time length of the collected image data.
And S702, if the interval time reaches the specified duration, starting the next image data acquisition of the flat panel detector.
