Radio-TLC scanner detector for PET and SPECT nuclear medicine imaging is designed so that the detector and collimator are moved rather than the bed itself, so no additional operational space is required. The instrument is user-definable and generally takes between one and two minutes, depending on the level of radioactivity. The radio-TLC strips are supported by TLC support beds that accommodate different sizes, lowering the user’s finger exposure and preventing contamination of the instrument itself. It can be configured with either one or two detectors connected to the system at any one time. The two-detector configuration is particularly useful for labs that need a radio-TLC scanner and a radio-HPLC detector in the same system but have limited space (and money).
