Detailed Description
In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings, in which like reference numerals refer to like parts throughout.
"exemplary" means "serving as an example, instance, or illustration" herein, and any illustration, embodiment, or steps described as "exemplary" herein should not be construed as a preferred or advantageous alternative.
For the sake of simplicity, the drawings only schematically show the parts relevant to the present invention, and they do not represent the actual structure as a product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled.
In this document, "a" or "an" means not only "but also" more than one ".
Herein, the "frame rate of the X-ray medical apparatus" or "frame rate" refers to a frequency at which the X-ray medical apparatus presents images, and the lower the frame rate is set, the longer the time interval during which the images are presented to the operator of the X-ray medical apparatus.
In the case of a C-arm X-ray machine, a higher frame rate is typically selected for fluoroscopy to achieve as fast an exposure dose adjustment as possible. However, the maximum power of the X-ray generating device of the X-ray medical apparatus is closely related to the frame rate of the X-ray medical apparatus, and the higher the frame rate, the lower the maximum power, which may affect the imaging quality of the obese patient. The lower the frame rate, the higher the maximum power, and the more the exposure dose of the X-ray medical apparatus can be adjusted, so that the quality of the image formed by the X-ray medical apparatus is better.
The applicant found that: in order to obtain better image quality, the frame rate is adjusted by stopping the X-ray of the X-ray medical equipment in the prior art, and the examination is continued. If the manual adjustment mode in the prior art is broken through, the frame rate is automatically adjusted by utilizing the correlation among the parameters so as to automatically improve the image quality, the practice operation is more convenient, and the examination efficiency of the X-ray medical equipment can be greatly improved.
Illustrative embodiments of the invention are described below with reference to the accompanying drawings.
Referring first to fig. 1, fig. 1 is a schematic flow chart of an adaptive image quality optimization method according to an embodiment of the present invention. As shown in FIG. 1, the adaptive image quality optimization method 100 is for an X-ray medical device, the adaptive image quality optimization method 100 comprising:
step 110: judging whether a first condition is met;
step 120: judging whether a second condition is met; and
step 140: based on the first two determination results, correlation control is performed.
Specifically, in step 110, it is determined whether the actual exposure dose of the X-ray medical device is less than a target exposure dose. In practice, the target exposure dose may be set according to the condition of the subject. Meanwhile, the actual exposure dose of the X-ray medical equipment can be easily obtained by those skilled in the art, and the detailed description is omitted here.
In step 120, it is determined whether the power of the X-ray generating means of the X-ray medical apparatus reaches the maximum power. In step 140, the frame rate of the X-ray medical device is automatically adjusted in a predetermined manner based on the aforementioned determination result.
With continued reference to fig. 2, in the embodiment shown in this figure, the frame rate of the X-ray medical device is automatically reduced in a predetermined manner if the actual exposure dose is less than the target exposure dose and the power of the X-ray generating means reaches the maximum power. At this time, the adaptive image quality optimization method 100 may further include a determination step, i.e., step S130, to determine whether both the determination results of steps 110 and 120 are satisfied.
When the actual exposure dose does not reach the target exposure dose, the quality of the image formed by the X-ray medical equipment does not reach the expectation, and at the moment, if the power of the X-ray generating device reaches the maximum power, the frame rate of the X-ray medical equipment can be adjusted, so that the maximum power is changed accordingly. In the embodiment, the frame rate may be automatically reduced in a predetermined manner, thereby achieving the effects of increasing the exposure dose and improving the image quality.
The automatic frame rate reduction may be achieved in a number of ways. For example, the frame rate can be reduced to a predetermined value. For example, the current frame rate is 30fps, which can be directly reduced to 5 fps. Alternatively, the frame rate may be gradually decreased uniformly or non-uniformly until the frame rate reaches a preset value or the actual exposure dose reaches the target exposure dose. For example, the frame rate is stopped from being lowered when the frame rate reaches a preset value, or the frame rate is stopped from being lowered when the actual exposure dose reaches the target exposure dose. Also, the frame rate may be adjusted uniformly or non-uniformly over several discrete intermediate frame rate values, for example, frame rate 30fps may be adjusted to 5fps over several intermediate values, such as 20fps, 10fps, 7.5 fps. Compared with the mode of directly adjusting the frame rate to the preset value, the mode of adjusting the frame rate through a plurality of intermediate values can enable the whole frame rate adjusting process to be carried out in a mode that an operator of the X-ray medical equipment is not easy to perceive, and the use of the X-ray medical equipment is not affected.
The above process for frame rate adjustment is only illustrative, and the present invention is not limited thereto. Those skilled in the art can set various ways of adjusting the frame rate according to actual needs, such as decreasing the frame rate or increasing the frame rate, without departing from the technical principles taught by the present invention.
The various adaptive image quality optimization methods described above can be implemented by an internal controller of the X-ray medical device, or by an external adaptive image quality optimization apparatus.
