Problems solved by technology

Manual detection mainly has the following defects: (1) The operator manually operates radioactivity at close range, and the radiation dose received is relatively large, which is easy to cause radiation damage to the operator; (2) The speed of detection is greatly limited, resulting in low detection efficiency, A large number of personnel must be equipped to carry out testing at the same time

Embodiment 1

[0048] Such as Figure 1 to Figure 3 As shown, the remote automatic visual detection device for medical radioactive seed sources provided in this embodiment includes a frame 1, a feeding mechanism 2 installed on the frame 1, an X-direction transmission mechanism 3, and a detection mechanism 5, which are installed on the X-direction The Z-direction transmission mechanism 4 on the transmission mechanism and moves along the x direction, and the remote operation mechanism 6 connected with the feeding mechanism 2, the X-direction transmission mechanism 3, the Z-direction transmission mechanism 4, and the detection mechanism 5. The frame 1 is used to load various mechanisms, organically combine various stations, and realize the automation of the entire process. The feeding mechanism 2 completes the automatic feeding, and sends the single radioactive seed source to the feeding place. The X-direction transmission mechanism 3 is used to realize the movement of the Z-direction transmis...

Embodiment 2

[0058] This embodiment provides a remote automatic visual detection method for medical radioactive seed sources, which is implemented based on the remote automatic visual detection device for medical radioactive seed sources provided in Embodiment 1.

[0059] The remote automatic visual detection method for medical radioactive seed sources provided in this embodiment includes the following steps:

[0060] Step 1, automatic feeding: put the radioactive seed source to be detected into the vibrating plate 21, start the vibrating plate 21, the vibrating plate 21 starts to vibrate, adjust the position and direction of the radioactive seed source, and send it along the vibrating plate 21 in an orderly manner Feed chute 22.

[0061] After the vibrating plate is activated, the radioactive seeds are sent to the feeding trough 22 in an orderly manner along the spiral guide rail 212 of the vibrating plate.

[0062] Step 2, material discharge: the feeding trough 22 sends the radioactive ...

Abstract

The invention discloses a remote automatic visual detection device for a medical radioactive seed source. The device comprises a frame, and a feeding mechanism, an X-direction transmission mechanism and a detection mechanism which are mounted on the frame, a Z-direction transmission mechanism which is mounted on the X-direction transmission mechanism and moves along the x direction, and a remote operation mechanism which is connected with the feeding mechanism, the X-direction transmission mechanism, the Z-direction transmission mechanism and the detection mechanism. The invention further discloses a detection method based on the detection device. According to the detection device and the detection method, the full-automation distant-service feeding, sorting, transmission, detection and material recovering process of the radioactive source can be realized, manual operation of operators is reduced, and radiation dosage of the operators is reduced; detection on the radioactive source is accomplished through cooperation of an electronic microscope and a computer, 360-DEG omnibearing no-dead detection on a sealing port of the radiation seed source can be realized, detection accuracy is improved, and detection efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of material detection and relates to a medical radioactive material detection technology, in particular to a remote automatic visual detection device for a medical radioactive seed source and a detection method thereof. Background technique [0002] Radioactive seed sources are widely used in the fields of medicine, industry, agriculture, and material science, among which the medical field is the most widely used, mainly for the diagnosis and treatment of tumors. In recent years, the most commonly used medical radioactive seed sources include iodine-125 (I-125), palladium-103 (Pd-103), phosphorus-32 (P-32), gold-198 (Au-198) and so on. Among them, the I-125 seed source for prostate brachytherapy has been widely used in Europe, the United States and other countries, showing significant economic and social effects. The I-125 seed source mainly uses physical methods to 125 The I nuclide is adsorbed on silver ...
