Optimisation of output factor measurements using the Magic Plate 512 silicon dosimeter array in small megavoltage photon fields

A novel high-resolution 2D silicon array detector for small field dosimetry with FFF photon beams

“…Conceived as a 2D planar dosimeter for dose measurements in solid water, the Octa is sandwiched between two Perspex plates, each 5 mm thick. A small air gap on top of its SVs minimiz 22 . Experim Care C Systems using a in Table Figure Dose profiles were evaluated by comparing FWHM and penumbra values, which was taken as the distance between the 80% and the 20% isodose levels.…”

Technical Note: Angular dependence of a 2D monolithic silicon diode array for small field dosimetry

“…1) is necessary for mechanical protection of the silicon detector and to optimize the detector response to normally incident small radiation fields. 6,21,22 The MP512 data acquisition system (DAQ) is based on eight modules of 64-channel analog electrometers. 6,23,24 Each chip is interfaced to a quad analogue-to-digital converter (ADC).…”

Impact of a monolithic silicon detector operating in transmission mode on clinical photon beams

“…A new family of monolithic silicon detectors, the Magic Plate 512T (MP512T) and MP1024T, have been developed to fill the above gap in transmission detector technology and subsequent dose reconstruction. In-phantom dose measurements for SRS and SBRT QA [24]- [26] using the MP512T detector have been previously reported.…”
