What Virtual Phantoms does
Virtual Phantoms, Inc., founded in 2009 by faculty from Rensselaer Polytechnic Institute in collaboration with the University of Florida, is a privately held medical software company headquartered in Albany, New York, with 1-10 employees. The company develops and sells the VirtualDose suite, a web-based SaaS platform for patient-specific radiation dose calculation in medical imaging. Its core technology combines anatomically correct 3D patient phantoms (replacing stylized MIRD-5 models) with GPU-accelerated Monte Carlo simulation to compute organ-level and effective doses for CT, interventional radiology, and — most recently, in December 2025 — diagnostic radiography procedures.
The product family comprises VirtualDoseCT (flagship, launched 2013), VirtualDoseIR (2017), and VirtualDoseDX (December 2025), sharing a common validated physics engine, an Angular-based web UI, DICOM import, PDF/CSV/XML reporting, and an API for batch processing. Distribution combines direct enterprise SaaS subscriptions (single-seat, floating-seat, and enterprise site licenses) sold to medical physicists, radiologists, and radiation safety officers, with OEM licensing of the calculation engine to dose-management platforms including Sectra DoseTrack, INFINITT DoseM, Qaelum DOSE, Medsquare RDM, PACSHealth DoseMonitor, Aware REM Server, and GE Healthcare, plus regional resellers in China (LISIT) and Japan (Wisdom Technologies).
The company has grown organically without disclosed institutional funding, reaching 40+ direct end users worldwide (including Massachusetts General Hospital, Mayo Clinic, and Memorial Sloan Kettering) and supporting more than 100 peer-reviewed publications. Founder/CEO Dr. George Xu received the 2020 AAPM Edith H. Quimby Lifetime Achievement Award, reinforcing the company's positioning around scientific validation in the radiation dosimetry field.

Virtual Phantoms product offering
Product offeringCore offering
Virtual Phantoms develops and licenses web-based SaaS software (the VirtualDose suite) that calculates patient-specific organ-level and effective radiation dose from CT scans, interventional radiology procedures, and diagnostic X-ray exams. The products combine GPU-accelerated Monte Carlo simulation with anatomically correct 3D patient phantoms to deliver accurate, ICRP 103-compliant dosimetry for medical physicists, radiologists, and radiation safety officers at hospitals, academic centers, and OEM healthcare software partners.
Product overview
Virtual Phantoms offers VirtualDose, a comprehensive radiation dose estimation software suite built on GPU-based Monte Carlo simulation technology and anatomically correct 3D patient phantoms. The platform comprises three core products: VirtualDoseCT for computed tomography dose calculations, VirtualDoseIR for interventional radiology and fluoroscopic procedures, and VirtualDoseDX for diagnostic radiographic (X-ray) exams. All products share the same validated Monte Carlo physics engine and web-based SaaS architecture, providing consistent organ-level and effective dose calculations across imaging modalities for patient safety, protocol optimization, and regulatory compliance.

Products and services
- VirtualDoseCT Flagship software module for calculating patient-specific organ doses and effective dose (mSv) from CT scans, using anatomically correct 3D patient phantoms and GPU-accelerated Monte Carlo simulation. Supports customization of scan parameters (kVp, mAs, pitch, scan range) and is targeted at medical physicists, radiologists, and radiation safety officers at hospitals and academic centers.
- VirtualDoseIR Software module that estimates organ doses from interventional radiology and fluoroscopic procedures using anatomical phantoms and Monte Carlo simulation, supporting real procedure parameters including beam angle, field size, fluoroscopy time, and output in DAP or air kerma rate. Used by medical physicists and radiation safety officers to monitor and report interventional radiology dose.
- VirtualDoseDX Diagnostic radiography (X-ray) dose estimation module extending the validated VirtualDose Monte Carlo engine to standard radiographic exams, with a library of typical X-ray protocols and adjustable x-ray output, orientation, geometry, and flexible output units matching machine-reported data formats. Targeted at medical physicists and imaging departments needing patient-specific organ dose for X-ray procedures.
