Description

A lock rod structure for radiation positioning

This creation is about a lock rod structure for radiation positioning, and can reduce the time and labor cost of positioning for the quality assurance project of radiation equipment.

At present, the medical methods used to treat tumors mainly include surgical resection, radiotherapy and chemotherapy. The former two focus on the local control of the tumor, while the latter is systemic treatment. The so-called radiotherapy refers to when high-energy radiation is used to treat cancer or other diseases, it is called "radiation therapy", commonly known as X-ray therapy.

Regardless of the type of radiation therapy, before each patient is treated, the current radiation equipment will be subject to the basic daily quality assurance (Daily QA) process. The project content includes radiation dose, radiation location, and related parameters of the machine itself. The purpose of the correction and so on is to ensure the smooth follow-up process and to avoid unnecessary damage to other normal tissues or cells of the patient due to high-energy radiation.

As the recent radiotherapy has gradually changed from the original X-ray therapy to the use of proton radiotherapy, the advantage is that after the proton radiation reaches the Bragg lift of the tumor tissue, there is no dose at all, so higher doses of radiation can be given to achieve suppression or It is the effect of treating tumors in patients, which has a more significant effect in the distinguishing application of important or sensitive organs in the treatment of tumors nearby. Therefore, the positioning of radiation becomes even more important.

The title (if any) provided in this article is only for convenience and does not necessarily indicate the scope or meaning of the creation of the patent application.

The first embodiment

As shown in Figure 1, this creation is a lock rod structure 100 for radiation positioning, which includes: a lock rod 1 placed in a proper position of a treatment bed 4; at least two positioning members 11 are set in Above the lock rod 1; and two fixing members 2 are respectively provided at both ends of the lock rod 1, and each of the fixing members 2 is provided with a convex portion 21, and is separated from the holes 41 on both sides of the treatment bed 4 Combine and fix the structure 100 of the lock rod 1.

In the use state, as shown in Figure 2, the user will place the lock bar structure 100 on the treatment bed 4 according to the current needs, which can be used to assist in positioning the position of the radiation. The corner point 3 (isocenter), and the positioning members 11 of the lock rod structure 100 are designed with different shapes (for foolproof), so that when the correction device 5 is installed later, there will be no reverse installation.

In the first embodiment, the design of the lock rod structure 100 for radiation positioning on the positioning member 11 is designed to prevent foolishness. By using two different shapes or different directions, when the user prepares When the correcting device 5 is fastened to the positioning members 11, the shapes of the positioning members 11 are not the same, so that only a single direction can be completely fastened, thereby preventing the correcting device 5 from being installed in the direction. The opposite situation.

The calibration device 5 used in this creation is usually a detector, but it is also called a detector. Generally speaking, the relevant person uses the detector to confirm the parameters of the particle beam and the correctness of the radiation dose delivery, but in the process of using the detector, it is often necessary to manually display on the screen. The displayed result determines whether the positioning is successful or dispatches manpower to adjust the position of the detector next to the treatment bed 4 and the person watching the screen to complete the daily positioning process.

When the radiation instrument is calibrated, the offset distance between the vertical irradiation point of the radiation and the at least one positioning point of the calibration device 5 is calculated to obtain a value. If it is less than a specific value, it means the positioning is completed.

Second embodiment

A lock rod structure 100 for radiation positioning of the present invention further includes a tank 6 to provide a space for placing a calibration device 5, wherein the bottom of the tank 6 is provided with at least two holes 62 that can be connected to the lock rod structure. The positioning pieces 11 of 100 are tightly buckled.

As shown in Fig. 3, when the radiological equipment performs positioning calibration, a calibration device 5 (such as a detector or a detector) is placed on the treatment bed 4 and connected to the computer equipment through the calibration device 5 Software to help determine whether to complete the positioning process.

However, the lock rod structure 100 of the present creation does not require a hole at the bottom of the correction device 5 as a necessary condition. Therefore, the present creation further includes a trough body 6. In addition to the lock rod structure 100 originally used, the trough body 6 is provided inside. There is a bottom plate 61 which is made of plastic or acrylic material.

When the user thinks that the bottom of the calibration device 5 cannot be punched, the calibration device 5 can be put into the tank 6, and the bottom plate 61 of the tank 6 is provided with the lock rod structure 100. Waiting for the hole 62 where the positioning member 11 is fastened, so only the correcting device 5 needs to be placed in a proper position inside the tank 6 to perform the related process of radiation positioning.

The third embodiment

This creative application can not only use a lock rod structure 100 and a tank 6 to The process of assisting radiation positioning can also be adjusted according to the needs of users. As shown in Figure 4, before performing the radiation positioning process, place two lock rod structures 100 on the treatment bed 4, and select a trough that meets the size requirements according to the position of the isocenter 3 of the radiation instrument to be positioned in the past 6. The groove body 6 is used to buckle the plurality of positioning members 11 on the lock rod structures 100, so the bottom plate 61 of the groove body 6 is provided with holes 62 corresponding to the number of positioning members 11, and only need to After the calibration device 5 is placed in the tank 6, the subsequent radiation positioning process can be performed.

Also because the positions of the lock rod structures 100 and the tank body 6 are the isocenter 3 positions of the radiological instrument to be positioned, after the first positioning is completed, record that the lock rod structures 100 are placed on the treatment bed After the position of 4 and the size of the tank 6 used, it can be quickly assembled every time thereafter for daily positioning and quality assurance. The relevant personnel only need to put the calibration device 5 into the tank 6 and use the computer or Manually confirm whether the positioning is completed.
