Hermia | Voxel Dosimetry
Hermia is the most complete Voxel Dosimetry software on the market. Save time with semi-automatic liver, kidney, spleen, and lung segmentation.
A personalized approach to dosimetry with Hermia Voxel Dosimetry
Hermia Voxel Dosimetry* supports a wide range of therapy and imaging isotopes, helping make personalized therapy a reality for your clinical practice. It is CE-marked and FDA cleared.
ONE WORKFLOW FOR ALL YOUR DOSIMETRY WORK
Process DICOM images from all camera manufacturers using the same workflow with automatic alignment of multiple SPECT/CT or PET/CT time points including deformable registration. Cumulated activity in each voxel is calculated at the voxel or organ level, and a Monte Carlo algorithm simulates photon absorption and scatter through the patient’s CT to calculate dose deposition over the entire field of view. Draw regions with automatic organ segmentation or versatile manual drawing and editing tools. Visualize the calculated total absorbed dose distribution, dose volume histograms and dose results table.
Review of the 3D dose map with semi-automatic organ regions and dose volume histogram analysis.

Pure theranostic approach
Support for a wide range of therapy and imaging isotopes:*** Ac-225; At-211; F-18; Ga-68; Ho-166; l-123; l-124; l-131; ln-111; Lu-177; Pb-203; Pb-212; Ra-223; Tc-99m; Y-90; Zr-89.
-
Validated Monte Carlo Algorithm
Extensive clinical validation of the accuracy of the dose results in patients and phantoms is published in peer reviewed journals (1-5).
-
Single time point dosimetry
Apply an effective half-life per organ, use the Hänscheid method (6) or assume physical half-life to calculate doses** from only one imaging time point post-therapy.

Personalised Theranostics for Good Clinical Practice in RPT
”Theranostic dosimetry software has progressed in leaps and bounds in recent years. Once the preserve of researchers with complicated spreadsheets requiring hours of processing time per patient, dosimetry can, and must, now enter the clinical mainstream. We owe it to the patients to optimise this powerful tool in the fight against cancer."
Tom Francke, Assoc. Prof, CEO of Hermes Medical Solutions
Personalized Dosimetry is Essential for NETs
Peptide receptor radionuclide therapy (PRRT) is a powerful tool in the fight against neuro-endocrine tumors (NETs). But the complexities of tailoring the treatment to each individual patient present a challenge to both clinical departments and software companies. In this article we describe a multi-disciplinary effort to overcome the challenges and deliver the optimal treatment for patients.
