[ detailed description ] embodiments
For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Fig. 1 shows a flowchart of a medical photography control method of an embodiment of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a medical photography control method, including:
And 104, calculating the corresponding image magnification according to the position information of the stand and the position information of the region of interest.

And 106, determining required detector parameters and X-ray emitter parameters according to the image magnification, so as to carry out medical photography according to the required detector parameters and X-ray emitter parameters.
Since the image magnification is determined, the imaging parameters of the photographic image, i.e. the detector parameters and the X-ray emitter parameters at the determined image magnification, at which the predetermined resolution and the predetermined contrast can be obtained, can be calculated in accordance with a predetermined image quality criterion, i.e. in accordance with the predetermined resolution and the predetermined contrast. Therefore, the controller adjusts the shooting parameters to the obtained detector parameters and X-ray emitter parameters, and medical shooting is carried out, so that a shot image meeting the preset resolution and the preset contrast can be obtained.
Wherein the predetermined image quality criteria, i.e. the predetermined resolution and the predetermined contrast, are settable and modifiable by the user at the medical photographing apparatus to suit actual patient detection needs.

In the above embodiment of the present invention, optionally, the rack position information includes: one or more of a source image distance, a source object distance, and an object image distance, wherein the source image distance is equal to the sum of the source object distance and the object image distance. When the stand is of an integral structure, the positions of the X-ray emitter and the detector are relatively static, so that all stand position information can be obtained only by obtaining any one of the source image distance, the source object distance and the object image distance. Of course, the X-ray emitter and detector on the gantry may be separate structures, in which case multiple items of source image distance, source object distance, and object image distance are required to determine the entire gantry position information.
In the above embodiments of the present invention, optionally, the detector parameters include one or more of pixel size, image readout mode, integration time, frame rate, and dose level; the X-ray emitter parameters include one or more of focal spot size, pulse frequency, pulse width, and radiation power.

In one implementation of the present invention, the X-ray emitter parameters include a focal spot size and one or more of a pulse frequency, a pulse width and a radiation power, although the X-ray emitter parameters are not limited to these, and may be any other parameters as needed.
In the above, the detector parameters and the X-ray emitter parameters are included in the imaging parameters, and in an actual scene, the more and more detailed the types of the determined imaging parameters are, the more the accuracy of medical imaging is ensured, so that the imaging effect can be improved, and diagnosis is facilitated.
Specifically, step 106 includes: selecting a pixel size and a focus size that satisfy a predetermined image quality standard according to the image magnification; determining a corresponding dose level based on the pixel size and the focus size.
In other words, the image magnification may be calculated based on the current surgical procedure position, i.e. the position of the region of interest, and the gantry position, and a suitable combination of focus size and pixel size, typically related to the dose level of the photography mode, may be automatically selected based on the image magnification, so that the corresponding dose level may be further determined.
Further, step 106 further comprises: acquiring the characteristics of a surgical site in an area of interest; determining the associated detector parameter and the X-ray emitter parameter from the image magnification and the surgical site feature.
Because the optimal photographing parameters corresponding to different surgical parts are different, the characteristics of the surgical parts can be used as a basis for setting the photographing parameters and combined with the image magnification, and photographing parameters such as the combination of the proper focus size and the pixel size, the dose level and the like are selected together, so that the practical scene can be adapted to after the characteristics of the current clinical surgical parts are increased, and the practicability and the imaging effect of medical photographing are further improved.
In one implementation of the present invention, an image of a surgical site within a region of interest may be acquired and the surgical site features corresponding thereto may be identified by performing edge sharpening or the like on the image of the surgical site.
In another implementation of the present invention, when medical imaging is performed on different surgical sites, it is often necessary to select a corresponding imaging protocol, and therefore, the surgical site features in the region of interest can be determined by the selected imaging protocol.
