RADIANCE. The first intraoperative radiation therapy treatment planning system

http://www.gmv.com/en/Products/radiance/

Intraoperative Radiotherapy (IORT) is a modality of cancer treatment that combines the effort of two disciplines, surgery and radiation therapy, in order to increment the rate of tumor control. In this treatment technique a high and localized dose of radiation is administrated directly to the exposed tumor bed during the surgery performed to extract the tumor.

Radiance is the first treatment planning system specially designed for IORT, CE and FDA certified. It has been designed to work with either X-rays IORT devices like the INTRABEAM® System as well as all electron IORT (IOERT) devices like mobile LINACs (MOBETRON, NOVAC, LIAC), and conventional LINACs when adapted to be used for this radiotherapy technique.

Radiance has been developed by GMV company, and it is the result of a multidisciplinary team composed of private companies (Técnicas Radiofísicas), medical institutions (Hospital Universitario Gregorio Marañón, Consorcio Hospitalario Provincial de Castellón, Clínica La Luz, Hospital Ramón y Cajal) and universities (Universidad Politécnica de Madrid, Universidad Complutense de Madrid, Universidad Rey Juan Carlos, Universidad de Valencia, Universidad de Granada).

In the framework of several funded projects (ENTEPRASE PSE-300000-2009-5, XIORT IPT-2012-0401-300000, PRECISION IPT-300000-2010-3), GFN-UCM group has focused on the development, implementation and evaluation of a dosimetric tool capable of providing a realistic dose distribution from any IOERT dedicated accelerator or INTRABEAM applicator that can be used for dose treatment planning in the OR during an IORT treatment. To do this we have done two mayor contributions to the dose calculation algorithms implemented in radiance.

First, we have developed a fast tuning tool to generate phase space files optimized to any user's device providing as input only an experimental DDP in water [1,2,3]. Second, we have developed a dose calculation code suitable for the INTRABEAM working energies that includes the accuracy of a Monte Carlo method and calculates dose distributions in a fraction of time [4,5]. The combination of both contributions allows the user to obtain a dose distribution from a phase space file tuned to reproduce his device within minutes.
