Problems solved by technology
Due to various reasons, for a long time, only a few medical institutions have carried out calibration and measurement of afterload sources, and a considerable number of medical institutions only formulate radiotherapy plans for patients according to the parameters provided by the manufacturers, and perform radiotherapy for patients, which brings potential harm to patients. It is easy to lead to the occurrence of medical accidents in radiotherapy

The invention discloses a well-type ionization chamber used for after-loading source measurement. The well-type ionization chamber includes an upper cover board, an upper insulator, a housing cylinder, a high voltage electrode, a receiving electrode, a lower insulator, a liner flange, a support base, a bottom cover board, a press block and an adapter connecting end. The top end and the bottom partof the housing cylinder have openings. The bottom cover board is mounted on the bottom opening of the housing cylinder and the upper cover board is mounted on the top opening of the housing cylinder,so that the bottom opening and the top opening of the housing cylinder are sealed and an inner space of the well-type ionization chamber is formed. The press block covers the bottom cover board and the liner flange covers the press block. The lower insulator is mounted on the liner flange. The high voltage electrode and the receiving electrode are vertically mounted on the lower insulator. The upper insulator is mounted on the top end of the high voltage electrode and the receiving electrode. The upper insulator and the lower insulator enable electric isolation between the high voltage electrode and the receiving electrode. The support base is mounted on the bottom part of the bottom cover board and penetrates through the bottom cover board and the press block to connect with the linear flange tightly. The adapter connecting end is mounted on the upper cover board and is used for connecting with an ionization chamber adapter.
Description
technical field [0001] The invention relates to ionization chamber technology, in particular to a well type ionization chamber. Background technique [0002] Since the 1970s, my country has used brachytherapy to carry out cancer treatment activities, and it has a history of more than 30 years. Due to various reasons, for a long time, only a few medical institutions have carried out calibration and measurement of afterload sources, and a considerable number of medical institutions only formulate radiotherapy plans for patients according to the parameters provided by the manufacturers, and perform radiotherapy for patients, which brings potential harm to patients. It is easy to lead to the occurrence of medical accidents in radiotherapy. Contents of the invention [0003] The invention provides a well-type ionization chamber capable of calibrating and measuring afterload sources. The present invention is achieved through the following technical solutions: [0004] A well-...
