Atomlab 950 Thyroid Uptake Software

The Atomlab 950 provides a choice of four pre-programmed uptake study protocols, with provision to modify any procedure to suit specific requirements.

Atomlab software guides the user through each step of any defined procedure to count the standard, lab background, patient thyroid, and patient background, and then automatically computes uptake percentage. The system allows multiple uptakes at varied intervals for each patient.

Automatic decay correction calculates elapsed time between dose count and actual patient thyroid count. It is therefore not necessary to perform thyroid counts in exact hourly increments from times of dose counts. Results are calculated either from decay-corrected dose counts or by recounting a standard.

The system calculates absorbed dose and biologic half life for I-131 for a time activity report. Reports show user-defined normal ranges for comparison, and have provision for entering individualized notes and comments.

Preset Thyroid Uptake Protocols

1. Automatic Count Time with Automatic Isotope Decay – Atomlab Software calculates count time to satisfy a level of accuracy established by the technologist. High count rate offers the advantage of short count time when counting the capsule. Because the system calculates decayed activity of the dose, recounting a standard is unnecessary.

2. Automatic Count Time with Recounting a Standard – The system calculates the appropriate counting time based on the count rates and desired accuracy. A standard is maintained to recount for the decayed activity.

3. Manual Count Time with Automatic Isotope Decay – The technician sets the count time for four separate counts used to calculate uptake – generally 60 seconds each. The system monitors elapsed time and calculates decayed value for administered dose.

4. Manual Count Time with Recounting a Standard – The technician sets count time for four separate counts, then recounts standard and lab background, and counts the thyroid, and patient background – generally 60 seconds each.
