What common factor is evaluated during camera calibration?

During camera calibration, a key focus is typically on the camera's sensitivity to gamma radiation. This characteristic is crucial because it affects how well the camera can detect and quantify the radiation being emitted from a radiopharmaceutical following injection into a patient. Sensitivity is vital for ensuring accurate and reliable imaging results, which can influence diagnostic outcomes in nuclear medicine.

While factors such as spatial resolution, cost of operation, and speed of image acquisition are important considerations in the broader context of camera performance and clinical efficiency, they are not the direct focus during the calibration process. Calibration is specifically aimed at ensuring that the camera functions effectively with respect to its detection capabilities, particularly concerning gamma radiation sensitivity, to produce images of the highest quality and reliability for patient care.
