Abstract: The present invention is a method of radiation position, which includes: placing a locking bar member on a proper position of a treatment bed; selecting positions respectively on two sides of the treatment bed to be joined with two ends of the locking bar member; and providing a calibration device, wherein the calibration device is provided with at least one positioning point, so that the bottom part of the calibration device is buckled with at least two positioning elements on the locking bar member; and calculating an offset distance between an irradiation point of a radiation and the at least one positioning point of the calibration device to obtain a value, wherein if the value is less than a deviation value, it represents completion of a positioning. The purpose of the present invention is to provide a method of quick and precise radiation position, which can not only reduce time cost but also increase the daily use frequency of a radiological apparatus to facilitate cost recovery.

Abstract: A detector for measuring scanning ion beams in radiation therapy sequentially includes a first high voltage electrode, a first spacing member, and a segmented electrode. The first spacing member is connected to the first high voltage electrode and the segmented electrode to form a first ionization cavity. The first ionization cavity is formed with a plurality of first reading electrodes and a plurality of second reading electrodes therein. A second spacing member and a second high voltage electrode are further sequentially disposed. The second spacing member is connected to the second high voltage electrode and the segmented electrode to form a second ionization cavity. The first reading electrodes and the second reading electrodes are respectively formed in the first ionization cavity and the second ionization cavity. With the first reading electrodes and the second reading electrodes in different directions, highly accurate space resolution, space dosage and scanning speed are achieved.
