HybridViewer Dosimetry™ & OLINDA/EXM® 2.0

Providing Organ Specific Dose

HybridViewer Dosimetry™ and OLINDA/EXM® v2.0 are now coupled together to make dosimetry from imaging easier. It also eliminates the errors associated with manually transferring data to spreadsheets for absorbed dose calculations. Whether the patient imaging is all Whole Body, or if there is an additional single SPECT or SPECT CT, or even a full multi-time point SPECT series, Hermes HybridViewer Dosimetry gives you the tools to generate per organ doses in less time than most inhouse designs, and with reliable repeatability.

The HybridViewer Dosimetry™ program provides a fast and efficient way to generate residence time from patient imaging and performs MIRD absorbed dose calculations using the following data types as input:

  • Multiple wholebody
  • Multiple wholebody + one SPECT/CT (SPECT-CT is used to normalize whole body time-activity curves)
  • Multiple SPECT/CT or PET/CT

OLINDA/EXM® V2.0 is used for the calculation of internal radiation dose estimates for radionuclides used in nuclear medicine. The application has a library of phantoms which permit the calculation of these doses for individuals of different age and size and for women at different stages of pregnancy. In addition, the application has incorporated results for a number of different organ systems not included in these whole body phantoms, specifically a model of the prostate gland, peritoneal cavity, head and brain, multipart kidney, and unit density spheres.

OLINDA/EXM® V2.0 has the same function as OLINDA/EXM® V1.1 but has incorporated new radionuclide decay data and new human and animal model data, both based on standards published after the release of OLINDA/EXM® V1.1. The previous generation of anthropomorphic phantoms were based on the Oak Ridge models, which employed geometrical shapes to define the body and its organs. These models have been replaced with realistic, NURBS-type models based on the recent standardized masses defined by the ICRP in its publication 89. These and other new models have been implemented in a new version of the OLINDA/EXM® V2.0 code.
