Detailed Description
For a clearer understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals refer to like parts throughout the various views.
In this document, "schematic" means "serving as an example, instance, or illustration," and any illustrations, embodiments described herein as "schematic" should not be construed as a more preferred or advantageous solution.
For the sake of simplicity of the drawing, the parts relevant to the present invention are shown only schematically in the figures, which do not represent the actual structure thereof as a product. Additionally, in order to simplify the drawing for ease of understanding, components having the same structure or function in some of the drawings are shown schematically with only one of them, or only one of them is labeled.
Herein, "a" and "an" mean not only "the one alone" but also "more than one" cases.
Herein, "frame rate of an X-ray medical device" or "frame rate" refers to a frequency at which the X-ray medical device presents images, the lower the frame rate is set, the longer the time interval at which images are presented to an operator of the X-ray medical device.
Taking a C-arm X-ray machine as an example, to achieve as fast an exposure dose adjustment as possible, a higher frame rate is typically chosen for fluoroscopy. 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 is, the lower the maximum power is, which has an influence on the imaging quality of the obese patient. The lower the frame rate, the higher the maximum power, and the greater the exposure dose of the X-ray medical apparatus can be adjusted, so that the better the quality of the image formed by the X-ray medical apparatus.
The applicant found that: to obtain better image quality, it is often necessary in the prior art to stop the X-rays of the X-ray medical device to adjust the frame rate and continue the examination. 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 practical operation is more convenient, and the inspection efficiency of the X-ray medical equipment can be greatly improved.
Exemplary embodiments of the present invention are illustrated in 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 used for an X-ray medical apparatus, and the adaptive image quality optimization method 100 includes:
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 judgment results, the correlation control is performed.
Specifically, in step 110, it is determined whether the actual exposure dose of the X-ray medical apparatus is smaller 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 apparatus is easily obtained by those skilled in the art, and will not be described herein.
In step 120, it is determined whether the power of the X-ray generating device of the X-ray medical apparatus has reached a maximum power. In step 140, the frame rate of the X-ray medical device is automatically adjusted in a predetermined manner based on the foregoing determination.
With continued reference to fig. 2, in the embodiment shown in this figure, if the actual exposure dose is less than the target exposure dose and the power of the X-ray generating device reaches a maximum power, the frame rate of the X-ray medical apparatus is automatically reduced in a predetermined manner. At this time, the adaptive image quality optimization method 100 may further include a determining step, i.e. step S130, to determine whether the determination results of steps 110 and 120 are both satisfied.
When the actual exposure dose does not reach the target exposure dose, the image quality of the X-ray medical equipment often does not reach the expected value, and 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 also changes. In an 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 reduction of the frame rate can be achieved in a number of ways. For example, the frame rate may be reduced to a predetermined value. For example, the current frame rate is 30fps, which can be reduced directly to 5fps. 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 stops being reduced when the frame rate reaches a preset value, or when the actual exposure dose reaches a target exposure dose. Also, the frame rate may be adjusted uniformly or non-uniformly across several discrete intermediate frame rate values, e.g., the frame rate 30fps may be adjusted to 5fps across several intermediate values such as 20fps, 10fps, 7.5 fps. Compared with the mode of directly adjusting the frame rate to a 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 procedure for frame rate adjustment is only illustrative, and the invention is not limited thereto. Those skilled in the art can set various ways of adjusting the frame rate, such as decreasing the frame rate or increasing the frame rate, according to actual needs without departing from the technical principles taught by the present invention.
The various adaptive image quality optimization methods described above may be implemented by an internal controller of the X-ray medical device or by an external adaptive image quality optimization device. The following are examples, but the invention is not limited thereto.
