Whole body counter developed by Baltic Scientific Instruments is intended for location and analysis of radionuclides in human body. The system is flexible to perform analysis of nearly any part of the body like joints, lungs, thyroid, etc. Having two HPGe detectors, the system provides outstanding measurement result in terms of accuracy and measurement speed. Depending of HPGe detector type (GCD or GCDX) it is possible to cover wide energy range, which means the list of radionuclides is so big that nothing will remain without attention of the specialist.
In some cases, longer acquisition is required, therefore, the examined person has comfortable ergonomic chair to be fixed for long measurement and still feel comfortable. Hydraulic mechanism of the chair together with adjustable positioning mechanisms of detectors allow to pick up almost any point of the body for measurement, keeping the examined person relaxed.
From the point of view of the specialist (operator), the software interface remains simple and intuitive allowing to control both HPGe detectors simultaneously summing the measurement result or operating each HPGe detector separately.
After measurement is finished, the operator will be able to see use electronic version of the report or print it out with one click. Content of the report is possible to adjust according to specific needs by editing the report template.
