PTW's Device for Advanced Verification of IMRT Deliveries (DAVID) is a measurement system developed to provide a precise and reliable instrument for monitoring administered photon beams in IMRT irradiation.
According to the company, there was previously no satisfactory option for checking treatment consistency without large amounts of extra work. The newly developed DAVID system closes this gap in quality assurance for IMRT treatments. Using DAVID, patient doses are monitored in-vivo and every treatment is documented completely without any additional time required.
