In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings, in which like reference numerals refer to like parts in the drawings.

"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, only the parts relevant to the present invention are schematically shown in the drawings, 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 ".

First, refer to fig. 1. Fig. 1 is a schematic view of an X-ray medical device according to the present invention. As shown in fig. 1, the X-ray medical apparatus 100 includes: an X-ray generating device 10, a beam of light 20, an X-ray detector 30 and at least one distance measuring sensor 40. Wherein, the X-ray generating device 10 is used for emitting an X-ray, the beam splitter 20 is arranged at the front side of the X-ray generating device 10, the X-ray detector 30 is used for receiving the X-ray, and the distance measuring sensor 40 is arranged at the beam splitter 20 and can be used for calculating the thickness of an object to be measured (as shown in the figure, a person to be measured 50). In the embodiment shown in fig. 1, one ranging sensor 40 is illustrated for example, however, the present invention is not limited in this respect, and one skilled in the art may arrange two or more ranging sensors 40 according to actual needs.

In an embodiment, various suitable distance measuring sensors 40 may be selected, for example, distance measuring sensor 40 may be a Time of Flight (TOF) sensor, an ultrasonic sensor, an infrared sensor, or a laser sensor, but the invention is not limited thereto.

The working principle of the present invention is described below with reference to fig. 1. As shown in FIG. 1, SID represents the distance from the X-ray source (not shown) in the X-ray generator 10 to the detector body (not shown) in the X-ray detector 30, OS1 represents the distance from the X-ray source to the distance measuring sensor 40, OS2 represents the distance from the detector body to the surface of the X-ray detector 30, and SOD represents the distance from the X-ray source to the body of the subject. It is easily understood that the body thickness BT of the subject can be calculated by the following formula using the above parameters:

BT＝SID–SOD–OS2。

wherein the distance SID of the X-ray source to the detector body and the distance OS2 of the detector body to the shell surface of the X-ray detector 30 are known parameters. The distance MV from the distance sensor 40 to the body of the subject can be measured, and the value of SOD can be obtained by summing the measured distance MV with the known distance OS1 from the X-ray source to the distance sensor 40. Thus, the body thickness BT of the subject can be obtained by calculation.

In a variation, a correction parameter d may be preset to compensate for the error in consideration of the possible error of the distance MV measured by the distance measuring sensor, so as to improve the measurement accuracy. Specifically, the distance from the X-ray source to the object to be measured can be measured in advance by using a measuring tool (e.g., a ruler, a tape measure, etc.), and recorded as RV, where the object to be measured can be a human body or various objects that can be used to simulate the person to be measured in practice, and the present invention is not limited in this respect. Thus, the value of the correction parameter d can be calculated by the following formula:

d＝RV–(MV+OS1)。

in practice, the d values under different distances MV can be measured in advance for multiple times and stored in a table form to form a correction parameter table for facilitating subsequent calling. Further, the value of d may be recorded by averaging a plurality of measurements. Thus, in consideration of the correction parameters, the SOD can be calculated in the subsequent calculation by the following formula:

SOD＝(MV+OS1)+d。

in embodiments, the correction parameter table may be provided in one or more dimensions to accommodate the use of one or more sensors as desired, although the invention is not limited in this respect.

The above calculation process may be performed by the control system of the X-ray medical apparatus 100, or a processing unit may be disposed on the beam splitter 20 adjacent to the distance measuring sensor 40 (optionally, the distance measuring sensor 40 may be packaged with the processing unit in a housing) to perform the corresponding calculation process, and the calculation result is fed back to the control system of the X-ray medical apparatus 100 to set the inspection parameters, which is not limited in this respect.

The distance measuring sensor 40 may be disposed at a suitable position on the beam splitter 20 according to actual needs by those skilled in the art, and the distance measuring sensor 40 may be disposed parallel to the beam splitter 20 or at an inclined angle with respect to the beam splitter 20. For example, can make distance measuring sensor 40 be certain inclination for light ware 20 when installation distance measuring sensor 40 to satisfy specific application demand, this inclination should be considered in above-mentioned calculation process this moment and carry out corresponding adjustment, the utility model discloses do not expand here and describe repeatedly.

In the above manner, the X-ray medical apparatus 100 can automatically calculate the thickness of the examinee and set the corresponding examination parameters accordingly. For example, the thickness of the person to be measured can be classified, such as thin gears, thick gears, moderate gears and the like, and when the thickness of the person to be measured falls into the corresponding gear, the prestored corresponding inspection parameters can be called. Alternatively, the respective inspection parameters may be calculated based on the thickness of each subject. Those skilled in the art can select a suitable manner to determine the inspection parameters according to the actual application requirement, and the content of the above illustration is not limited.

In the embodiment shown in fig. 1, the X-ray generator 10 is disposed on a cantilever and the X-ray detector 30 is disposed on a column, but the present invention is not limited thereto. In practice, the X-ray generating device 10 may be disposed on a cantilever or a column, and the X-ray detector 30 may be disposed on a column or in a bed. In other words, the technical solution taught by the present invention can be applied to various types of X-ray medical devices.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
