Abstract:
The disclosure relates to a device for detecting therapeutic radiation based on an optical disk with solar cells. The radiation detecting device may include at least one optical disk formed of a water-equivalent material, disposed perpendicular to a first direction in which the radiation is incident, and converting the radiation into visible light; a solar cell disposed on one side of the at least one optical disk, converting the visible light into an electrical signal; and a processing module for collecting and processing the electrical signal outputted from the solar cell.
Abstract:
The disclosed device for detecting the position and dose distribution of a therapeutic proton beam emitted in a pencil beam scanning mode comprises: a proton beam progressing position detection unit comprising a plurality of first optical fibers arranged along the first direction and a plurality of second optical fibers arranged along the second direction which is different from the first direction; and a proton beam dose distribution detection unit comprising a plurality of optical wavelength converter, each of which comprises an optical wavelength conversion disk and an optical wavelength-converting optical fibers arranged along the outer circumference of the optical wavelength conversion disk. The proton beam progressing position detection unit detects a proton beam progressing position through the arrangement of the first and second optical fibers, and the proton beam dose distribution detection unit detects a dose distribution of the proton beam progressing direction through a plurality of optical wavelength conversion disks.
Abstract:
Provided is a radiation irradiation device and method in which radiation intensity can be adjusted depending on an irradiation position. The device includes a radiation source, a target plate having an irradiation hole through which radiation emitted from the radiation source passes and having a first target stopper and a second target stopper formed to protrude on both surfaces, respectively, X-axis shield plates and Y-axis shield plates coupled to both sides of one surface of the target plate and including shield stoppers formed on a contact surface with the target plate and capable of being moved with respect to the target plate. The X-axis shield plate are coupled laterally with shield stoppers capable of moving laterally and the Y-axis plate are coupled longitudinally with shield stoppers capable of moving longitudinally. The shield stoppers can be moved between two first target stoppers or two second target stoppers adjacent to each other.
