Korea University Background
The present invention relates to a use of 3D-measure the irradiation position and the dose distribution of the radiation in real time in the three-dimensional scattering radiation imaging apparatus. It is possible to be used for 3D radiographic imaging device and radiation medical equipment.
Conventionally, the irradiation position and dose distribution of the source can be known through wire simulation and preliminary experiments. Conventional 3D imaging devices have a problem of treating radiation information scattered in the human body as noise during the radiation treatment. Therefore, the irradiation position and the dose distribution of the radiation are predicted in the radiation irradiation planning stage or the experimental value is measured.
Optimization of detector placement to obtain maximum detection efficiency.
Using the Detection unit for improving detection efficiency according to scattering distribution by incident energy of radiation according to Klein-Nishina formula.
A plurality of detectors in a Compton camera structure including a scintillator and an optical sensor.
Reverse direction of radiation incidence.
When detecting a large number of scattering lines, the position of the radiation source is detected without absorbing the total energy through a commonly estimated scattering position.
Radiation scattered positions can be recorded three-dimensionally and can be made into a four-dimensional matrix including absorbed energy.
3D measurement of irradiation position and dose distribution in real time.
Detecting scattered radiation position and energy and reverse the incidence direction of radiation
3D distribution of irradiated radiation beyond plane distribution can be obtained
Potential for use as radiation medical equipment
Observing the 3D distribution of the radiation to be irradiated through the real-time radiation measurement and to obtain the result without additional radiation dose.
The market for radiation detectors is expected to grow at an average annual rate of 4%, reaching $33 billion by 2020
High-sensitivity medical imaging, medical treatment, and security applications are expanding. As a result, the market size will continue to increase
