VirtualDose™ uses cutting-edge advances on Monte Carlo simulation software to estimate doses for CT and IR exposures and International Commission on Radiological Protection (ICRP) recommendations across multiple anatomically realistic patient phantoms for:
- Average (or median) adult patients
- Children at different ages (newborn, 1-, 5-, 10-, and 15-year-old)
- A pregnant female at three gestational stages (3-, 6-, and 9-month)
- Overweight and obese patients
SaaS Delivery. VirtualDose is designed as a Software as a Service (SaaS) platform to allow as many users as possible to access it at the same time via the Internet. SaaS is a new software distribution mode that eliminates installation and maintenance expenses and coordination issues.
Phantom Technology. We have conducted years of development and testing to yield effective results with a family of 15 anatomically realistic phantoms including the 2 adult male/female, 3 pregnant female (3-, 6-, and 9-month), and 10 male/female children (1-year-old, 5-year-old, 10-year-old, and 15-year-old) with the capability to adjust the body size and shape covering 5th- to 95th percentiles.
VirtualDose employs a Monte Carlo-based computational method for modeling various imaging parameters (energy spectrum, collimation, filtration and tube current) and clinical protocols. We support it with a comprehensive organ dose database built and maintained using the Monte Carlo scanner models and the organ-dose and effective-dose algorithms recommended in the ICRP-60 as well as in the more recent ICRP-103.
User-Friendly Interface. Our easy-to-use software graphical user interfaces uses 3D object-oriented programming for interactively displaying patients, selecting scanner parameters, and reporting user-friendly dose and risk information.
X-rays are emitted from a point at the location of the anode of the x-ray tube. The flat filter, the bow-tie filter and the beam shape were all considered. The CTDI phantom was used to validate the modeled MDCT scanner.
