Helgeson 'Quicky' In-Vivo Counter is designed to complement any health physics program which includes routine whole-body counting. The 'Quicky' is used to rapidly screen personnel or it can be used with a fixed counting time to obtain more precise results.

The printed results provide the documentation for subject identification, counting time and date. Results are reported in Becquerel or Nano curies. The 'Quicky' can reduce your regular counting requirements and costs significantly.

Software for the 'Quicky' is “user-friendly” with a menu format that provides a variety of standard and optional operating programs. System performance software includes a Quality Assurance program that checks the electronics of both the NaI(TI), reporting any errors to the operator. An Energy Calibration program allows the gains of the individual detector-amplifier systems to be adjusted to uniformity and conformity to the design parameters.

Helgeson can provide a complete turn-key in-vivo counting system or any portion thereof, including all necessary hardware, software, operating procedures, instruction manuals, installation and training. The equipment is designed to provide the customer with high quality, quantitative, low-maintenance in-vivo counter 24 hours a day, 365 days a year.
