Review of Compton camera imaging technology development
He jishu, 2021 Compton camera (CC) is a new type gamma-ray imaging modality. Because CC has no mechanical collimation structure, it has unique advantages in detection efficiency compared with other gamma-ray imaging modalities.

An easy and direct protocol based on planar molecular images to quantify 131I using thyroid phantom
Brazilian Journal of Radiation Sciences, 2023 A planar nuclear medicine image can be used to estimate dosimetry during iodine therapy. To this end, radionuclide activity distribution should be quantified in the patient’s body in terms of a calibration coefficient.
