Abstract
A radiation imaging apparatus 100 includes: a first detector 1 that detects single gamma rays; a plurality of second detectors 2 that detect annihilation gamma rays; and an image processing unit 3 that generates a first gamma ray image 10 based on the single gamma rays detected by the first detector 1 and generates a second gamma ray image 11 based on the annihilation gamma rays detected by the plurality of second detectors 2, wherein the image processing unit 3 is configured to enhance image quality of either one of the first gamma ray image 10 and the second gamma ray image 11 using the first gamma ray image 10 and the second gamma ray image 11.
Claims11
A radiation imaging apparatus, comprising:
- a first detector that detects single gamma rays;
- a plurality of second detectors that detect annihilation gamma rays;
- and an image processing unit that generates a first gamma ray image based on the single gamma rays detected by the first detector and generates a second gamma ray image based on the annihilation gamma rays detected by the plurality of second detectors, wherein the image processing unit is configured to enhance image quality of either one of the first gamma ray image and the second gamma ray image using the first gamma ray image and the second gamma ray image.
A radiation image processing method, comprising:
- a step of generating a first gamma ray image based on single gamma rays detected by a first detector;
- a step of generating a second gamma ray image based on annihilation gamma rays detected by a plurality of second detectors;
- and a step of enhancing image quality of either one of the first gamma ray image and the second gamma ray image using the first gamma ray image and the second gamma ray image.
