What type of imagery can help identify if a gamma camera has issues with spatial resolution?

Uniformity flood images are essential for assessing the spatial resolution of a gamma camera. These images are created by exposing the camera to a uniform distribution of radioactive sources, which allows for the evaluation of how well the camera can detect and image a consistent signal across its entire field. In a properly functioning camera, the flood image should appear uniform without any significant artifacts or variations in intensity.

Any deviations in the uniformity flood image, such as areas that appear brighter or darker than others, could indicate problems with the spatial resolution. This might suggest issues such as detector misalignment, malfunctioning pixels, or other hardware concerns that would impact the camera's ability to accurately reproduce spatial information.

Other options, such as time-lapse footage, intensity mapping, and live action imaging, do not specifically assess the spatial resolution capabilities of the gamma camera. These methods can provide information on other aspects of the camera's performance but are not tailored for identifying spatial resolution issues.
