MAGIC-fgel dosimetry for clinical electron beam

Development and Application of MAGIC-f Gel in Cancer Research and Medical Imaging

“…Another form of irradiation is protons and heavy ions, but due to the saturation effect, the dosimetric reaction is lower than that from using gamma and X-rays [37][38][39][40][41][42][43]. Most of the studies on MAGIC-f gel also used gamma rays and high-energy X-ray photons from different clinical linear accelerator sources; however, only one study by Pianoschi et al used an electron beam [44].…”

“…The MAGIC-f gel is analyzed by using the same diagnostic imaging techniques as other polymer gels, such as OCT, X-ray CT [12,[44][45][46], magnetic resonance imaging (MRI) [3,27,47,48], and ultrasound (sonography) [49][50][51]. Out of these techniques OCT and MRI are most popular based on the physical change occurring in gel due to irradiation [52].…”

“…Gel dosimetry is applied in various applications for radiation dose measurement where the conventional dosimeter will not give an accurate measurement [54]; the application of polymer gel which was developed before MAGIC-f gel is discussed in several works of the literature [3,8,[55][56][57][58]. The polymer gel dosimeter replaces the conventional dosimeter from the very basic dosimetry parameters such as percentage depth dose (PDD) in photons and electron beams, to the complex dosimetry parameters, due to its ability to demonstrate the dose distribution in three dimensions [25,44,58,59]. Moreover, the polymer gel has been applied to the dosimetry analysis in simple arrangements, such as nine-field tomotherapy [60], to a more complex anatomical situation, such as tangential breast cancer therapy [61,62] and scalp treatment with electron beams [63].…”

“…The electron beam therapy treatment in nuclear medicine is used to deliver a high dose rate. Pianoschi et al show that MAGIC-f gel can be utilized as a feasible dosimeter to measure the percentage depth dose (PDD) and beam profile in treatment planning as it has strong spatial resolution characteristics and can create three-dimensional dose distribution [44]. In that research, the response of MAGIC-f gel for a 6 MeV electron beam is studied using different doses and levels of dose along with the determination of dose-metric parameters for clinical beam such as PDDs and beam profile [44].…”

3D Dosimetric Tools in Radiotherapy for Photon Beams

“…Especially for use in techniques of high dose rate it can verify the volume dose as a quality control in radiotherapy. The gel dosimeter with formaldehyde (MAGIC-f) has been used in simulation studies as well as in clinical [8][9][10][11].…”
