Description

Technical Field

[0002] As is known to all, X-rays are electromagnetic radiation with a wavelength between ultraviolet rays and gamma rays. It is a very short wavelength electromagnetic radiation, with a wavelength of about (20 to 0.06) × 10-8 cm. X-rays are mainly used in the following aspects in medicine - diagnosis, treatment and protection.

[0003] Among them, X-ray therapy can be divided into tumor radiotherapy and superficial radiotherapy according to the depth of treatment. Tumor radiotherapy uses X-rays with high energy, strong penetration and deep irradiation to act on tumors in deeper parts, and achieve the purpose of treatment by destroying or inhibiting the irradiated cell tissues. Superficial radiotherapy uses soft X-rays, which is a low-energy radiotherapy with shallow tissue penetration. It is suitable for the treatment of superficial diseases, such as pathological scars (keloids, hypertrophic scars), warts, familial benign chronic pemphigus, keratosis pilaris and other benign skin diseases, as well as skin tumors such as squamous cell carcinoma of the skin and mycosis fungoides.

[0004] At present, X-ray radiotherapy systems are generally equipped with a filtering function to subdivide X-rays of different energy levels and achieve multi-mode treatment with different doses. However, in the related art, the filtering structure used to achieve the filtering function is prone to wear or deformation after long-term use, which will affect the quality of X-ray output, causing the filtering effect to deviate from the theoretical setting, and cannot guarantee the accuracy and effectiveness of X-ray treatment.

[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] In the related art, an X-ray generating and emitting component 200, taking the treatment head of an X-ray radiotherapy system as an example, includes a housing and an X-ray tube. The housing can be shielded to carry the X-ray tube and is provided with a ray emission port 210. Meanwhile, a filter is provided on the X-ray tube. The X-ray beam generated by the X-ray tube is emitted from the ray emission port 210 after the intensity level is adjusted by the filter. When the filter becomes thinner due to wear, the dose / dose rate of the X-rays actually emitted increases; when the filter becomes thicker due to bending deformation, the dose / dose rate of the X-rays actually emitted decreases; both of these deviate from the theoretical dose / dose rate data of the X-rays filtered and processed by the filter, and it is impossible to accurately ensure that the therapeutic effect of the X-ray radiotherapy system can reach the expected level.

[0047] In view of this, the embodiment of the present application provides a tool 100 for X-ray filtration detection, which is mainly based on the detection component 120 being able to detect the X-ray radiation dose after being processed by the filter element, and then by calibrating the measured X-ray radiation dose data with the theoretical effect data of the filter element, it is possible to quickly and accurately measure and determine whether the filtering effect of the treatment head is deviated, thereby facilitating more accurate and controllable treatment. The tool 100 of this embodiment uses the bracket component 110 to assemble the detection component 120 to the X-ray generating and emitting component 200 before use, so that the detection component 120 can be aligned with the ray emitting port 210 of the treatment head.

[0048] Reference Figures 1 to 6 As shown, the tool 100 for X-ray filtration detection includes:

[0049] A support member 110, the support member 110 is used to detachably fix the detection member 120 to the X-ray generating and emitting member 200;

[0050] The detection component 120 is limited by the support component 110 to be directly opposite to the ray emission port 210 of the X-ray generating and emitting component 200. The detection component 120 is used to detect the X-ray radiation dose after being processed by the filter.

[0051] In a possible implementation, the detection component 120 includes a filtering detection component 121 and a radiation quantitative component 122, which are respectively installed on the support component 110, and the filtering detection component 121 and the radiation quantitative component 122 are both arranged opposite to the radiation emission port 210, and the radiation quantitative component 122 is located between the radiation emission port 210 and the filtering detection component 121.

[0052] Reference Fig.10 During assembly, first install the support component 110 on the treatment head of the X-ray radiotherapy system, and then install the filter detection component 121 and the radiation quantitative component 122 on the support component 110 respectively, and keep the test centers of the filter detection component 121 and the radiation quantitative component 122 on the same axis, and align with the center of the radiation emission port 210.

[0053] In a possible implementation, the filter detection element 121 is configured as an ionization chamber 1211, and the ionization chamber 1211 is used to measure the actual radiation dose / actual radiation dose rate of the filtered X-ray 300.

[0054] In this embodiment, the filter element may include a plurality of filter plates of different thicknesses and a shielding plate. The filter element is configured to be coaxially rotatable relative to the X-ray tube so that one of the filter plates or the shielding plate is located at the exit of the tube, thereby achieving the purpose of adjusting different filtering effects or shielding effects, that is, realizing the switching of different functional modes. The finished filter plates of different thicknesses have theoretical filtering performance based on their own properties, and provide corresponding theoretical radiation dose / actual radiation dose rate of X-rays. Based on the ionization chamber 1211 as the filter detection element 121, the actual radiation dose / actual radiation dose rate obtained constitutes calibration data with the above-mentioned theoretical radiation dose / actual radiation dose rate, which meets the need to verify the filtering effect.

[0055] In a possible implementation, the radiation quantitative component 122 includes a baffle assembly 1221 having a quantitative hole 1221-3 and a baffle fixing frame 1222. The baffle assembly 1221 is configured to block the X-rays 300. The quantitative hole 1221-3 is arranged opposite to the radiation emission port 210. The two ends of the baffle fixing frame 1222 are respectively connected to the baffle assembly 1221 and the bracket component 110.

[0056] The function of the radiation dosing element 122 is to ensure that the amount of radiation irradiating the ionization chamber 1211 is determined. The X-ray 300 emitted by the treatment head only passes through the dosing hole 1221-3, and the other parts of the baffle assembly 1221 will block the X-ray 300, allowing only the central part of the X-ray 300 to pass through the dosing hole 1221-3, thereby ensuring the uniformity of the X-ray 300.

[0057] In one possible implementation, the baffle assembly 1221 includes an aluminum baffle 1221-2 and a lead baffle 1221-1, each of which is provided with a first quantitative hole 1221-2-2 and a second quantitative hole 1221-1-2, respectively. The aluminum baffle 1221-2 is wrapped around the outer surface of the lead baffle 1221-1, or the aluminum baffle 1221-2 is superimposed on the upper and lower surfaces of the lead baffle 1221-1, and the first quantitative hole 1221-2-2 and the second quantitative hole 1221-1-2 are aligned to form the above-mentioned quantitative hole 1221-3; preferably, the first quantitative hole 1221-2-2 and the second quantitative hole 1221-1-2 are both arranged at the center position of the lead baffle 1221-1 and the aluminum baffle 1221-2.

[0058] Reference Figure 7 Exemplarily, the baffle assembly 1221 is composed of two lead baffles 1221-1 and one aluminum baffle 1221-2 to form a sandwich structure. In another alternative implementation method not shown in the figure, the aluminum baffle 1221-2 can also be attached to the entire surface of the lead baffle 1221-1 to form the baffle assembly 1221. The aluminum baffle 1221-2 can attenuate X-rays to a certain extent, and can even shield a portion of low-energy X-rays; the lead baffle 1221-1 plays the main role of blocking X-rays. After combining with the aluminum baffle 1221-2, its shielding efficiency and effect can be further optimized. At the same time, the use of aluminum wrapping can also prevent the body from direct contact with lead, avoiding harm to the human body.

[0059] In a possible implementation, the bracket component 110 includes a bracket body 111 and a first mounting portion 112, a second mounting portion 113 and a third mounting portion 114 arranged on the bracket body 111; the first mounting portion 112 is arranged at the first end of the bracket body 111, and is used for detachably fixed connection with the X-ray generating emission component 200; the third mounting portion 114 is arranged at the second end of the bracket body 111, the second end and the first end are in a relative direction of the bracket body 111, and the third mounting portion 114 is used to fix the filtering detection component 121; the second mounting portion 113 is arranged at the connecting position of the first mounting portion 112 and the third mounting portion 114, and the second mounting portion 113 is used to fix the radiation quantitative component 122.

[0060] In one possible implementation, referring to Figure 1 and Figure 2 The bracket body 111 is configured as a fixed support plate 1111, and the width dimension of the fixed support plate 1111 decreases from the first end to the second end.

[0061] In practical applications, the specific structure of the bracket body 111 is not limited. For example, in this embodiment, the bracket body 111 can be a fixed support plate 1111. Preferably, when the overall shape of the fixed support plate 1111 is as shown in the figure, which is larger at the top and smaller at the bottom and has a gradual design, it is beneficial to strengthen the assembly strength at the first end, improve the connection stability of the entire tooling 100, ensure the constant position of the filtering detection component 121, the radiation quantitative component 122, and the X-ray generating and emitting component 200 after alignment, and facilitate the miniaturization, lightweight, and easy processing of the tooling 100. At the same time, the arc corner design of the fixed support plate 1111 is also beneficial to improve wear resistance and aesthetics, enhance the machinability of parts, and reduce stress concentration.

[0062] Furthermore, a reserved hole 1111-1 may be opened on the fixed support plate 1111 to replace the second mounting portion 113 and reserve for the baffle assembly 1221. The reserved hole 1111-1 may be arranged between the first mounting portion 112 and the second mounting portion 113 and aligned therewith.

[0063] In a possible implementation, the first mounting portion 112 is configured as a cover body 1121 integrally connected to the fixed support plate 1111; the cover body 1121 has a partial chamber 1121-1 that can accommodate the X-ray generating emission component 200, and the cover body 1121 is also provided with a plurality of connection holes 1121-2 for locking the partial part.

[0064] Among them, the chamber 1121-1 plays the role of positioning the tooling 100 and the treatment head. When in use, it is only necessary to put the cover body 1121 on the end of the treatment head. After the end is against the inner wall of the chamber 1121-1, the relative position of the two can be determined to meet the preset requirements. There is no further limitation on the shape of the cover body 1121, and the shape of the chamber 1121-1 of the cover body 1121 is adapted to the local shape of the X-ray generating emission component 200. For example, in this embodiment, the shape of the chamber 1121-1 is adapted to the shape of one end of the treatment head. Further, the connecting hole 1121-2 can be arranged on the peripheral side of the cover body 1121, and a locking knob can be used at the connecting hole 1121-2 to lock and fix the cover body 1121 and the treatment head.

[0065] In one possible implementation, referring to Figure 1 and Figure 3 The second mounting portion 113 and the third mounting portion 114 are respectively configured as a first through hole 1131 and a second through hole 1141 opened in the fixed support plate 1111, the baffle fixing frame 1222 is connected to the first through hole 1131, and the ionization chamber fixing frame 1212 for connecting the ionization chamber 1211 is installed in the second through hole 1141.

[0066] The shapes of the baffle holder 1222 and the ionization chamber holder 1212 are not further limited. For example, refer to Figure 8 The baffle fixing frame 1222 can be a double-headed connecting shaft 1222-1, one end of the double-headed connecting shaft 1222-1 is a baffle connecting head 1222-2, and the other end is a bracket connecting head 1222-3. For example, in this embodiment, the baffle connecting head 1222-2 can be a supporting platform 1222-2-1 formed at the end thereof, and the supporting platform 1222-2-1 is provided with a mounting hole 1222-2-2. The baffle assembly 1221 is placed on the supporting platform 1222-2-1 and then fastened. The parts are docked at the mounting hole 1222-2-2, and accordingly, the first fixing hole 1221-2-1 and the second fixing hole 1221-1-1 that are compatible with the mounting hole 1222-2-2 are respectively opened on the aluminum baffle 1221-2 and the lead baffle 1221-1; the bracket connector 1222-3 can be a first shaft section 1222-3-1 with a first annular groove 1222-3-2, and a first locking collar is installed at the first annular groove 1222-3-2 for docking and fixing to the first through hole 1131; refer to Fig. 9 The ionization chamber fixing frame 1212 can be a single-head sleeve 1212-1, and the interior of the single-head sleeve 1212-1 is provided with a channel 1212-1-1 for installing the ionization chamber 1211. The ionization chamber 1211 is placed in the channel 1212-1-1 by one end of the single-head sleeve 1212-1, and the other end of the single-head sleeve 1212-1 can also be a second shaft section 1212-2 with a second annular groove 1212-2-1. A second locking collar is installed at the second annular groove 1212-2-1 for docking and fixing to the second through hole 1141.
