ABSTRACT:
Methods and systems for calibrating a digital gamma camera using a hole phantom are described. In one embodiment, the method includes the steps of performing offset adjustments and gain adjustments, and then using a source to flood the hole phantom, image data of the phantom is collected by the camera to be calibrated. The image data collected from such flood is used to generate a light distribution function for the camera. In addition, residual distortions are measured, and a spatial corrections map and an energy deficit map are created. A quality control image also can be generated to verify that the camera is calibrated.
