The Atomlab 930 is a versatile and cost-effective spectrum analysis system for performing uptake studies, bioassays, Schilling tests, wipe tests, and other user-defined tasks in the nuclear medicine environment. Engineered for portability, durability, and efficiency, the 930 handles an array of clinical tests, safety compliance tasks, and system administration/QA procedures. A powerful microprocessor guides the user through procedures, automatically performs necessary calculations, and outputs clear, concise reports. The system’s internal memory stores results on up to twenty-five patients (up to four studies per patient).

The self-contained 930 system is configured on a mobile platform with locking casters and a base that measures only 30" by 31.5" (76 x 80 cm). A 2-tiered shelf supports the microprocessor/keyboard and printer. The base of the stand has a special shelf to hold an optional well counter. A 2" x 2" NaI(Tl) detector with collimator articulates on a counterbalanced arm. Twenty-two inches (56 cm) of vertical travel allows the probe to be positioned up to 55" (140 cm) from the floor to accommodate seated or supine patients. The probe swings more than 180° on the horizontal plane, and extends outward up to approximately 34" (86 cm) from the support column. This design makes positioning for uptake studies simple and comfortable for both patient and technologist, and allows the unit to be easily moved for a variety of applications or storage. The system’s multi-channel analyzer has 256 channels, with separate inputs connections for the probe and optional well counter. The system’s embedded software has specialized programs for thyroid uptake, bioassay, wipe test, Schilling test, manual (user-defined) rate counts, system administration and quality assurance, and start-up self test. Programs print out concise, easily interpreted reports.
