Study of commercial detector responses in non-equilibrium small photon fields of a 1000 MU/min CyberKnife system

Energy response corrections for profile measurements using a combination of different detector types

“…The SFD silicon chip has a side length of around 1.1 mm measured from a CT image and is typically simulated as disks of a diameter around 1.0 mm . The EDGE detector has been modeled with a slightly larger chip of 1.3‐mm side length . The 60012 also has been reported to be simulated with a diameter of 1.5 mm .…”

“…25,26 The EDGE detector has been modeled with a slightly larger chip of 1.3-mm side length. 27 The 60012 also has been reported to be simulated with a diameter of 1.5 mm. 26,28 Additionally, the unshielded 60012 still contains some high Z material in the form of a filter in the vicinity of the silicon chip, which is described in detail for the successor model 60017 in.…”

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

“…It was shown that it is possible to design a 'correction-free' detector, though, with the addition of low density media to the high density detector components 11 . However, it must be verified that these modifications are correctly compensating whatever the beam quality and measurements conditions 12 . 2D monolithic silicon diode array detectors, with either 2 mm and 3 mm pitch, have been shown to be promising as dosimeters by several groups 13,14 .…”

The effect of an air gap on a 2D monolithic silicon detector for relative dosimetry

“…As previously suggested by other authors, it would be necessary to verify that the introduced air gap is appropriate under any beam energy and measurement condition [28]. Further study will be dedicated to improving the current understanding of the relationship existing between the required amount of air gap, detector design, beam energy and measurement condition.…”
