The Ultimate... User Friendly... Intuitive

Performing Thyroid Uptake measurements has never been easier. The Captus 3000 combines a totally new software program with the latest PC technology to create a Thyroid Uptake system that is fast, reliable, and extremely easy to use.The Captus software has been designed to get you up and running in virtually no time at all. The program contains a "Quick-Start" feature that walks the user through all of the initial setup functions. The "Quick-Start" feature also serves as an excellent teaching tool.

The Captus 3000 software is a full service program with Thyroid Uptake, Wipe Testing, Bioassay, Schillings, Dicopac®, BloodVolume and RBC Survival functionality built in. The Wipe Test module has been a "New" feature that allows the flexibility of predefined or user defined groupings. The entire program has "Fly Over" control bars to allow quick access to whatever function is necessary. QA is of course completely automated and now includes a "New" feature for measuring Minimum Detectable Activity. With the use of the two included reference standards (Cs-137 and Eu-152) the system will move from Calibration to Constancy to Chi-square with limited time and effort.

There is a new and versatile 1024 Multichannel Analyzer (MCA) module that allows measurements of energies up to 2 MeV. The MCA module also has an isotope selection library with over 90 preloaded isotopes and adjustable ROI’s for easily reproducible counting parameters.
