Title: Innovations in Radiation Therapy: The Contributions of Feras M Aldweri
Introduction
Feras M Aldweri is a notable inventor based in Zarqa, Jordan, recognized for his significant contributions to the field of radiation therapy. With two patents to his name, Aldweri has focused on developing advanced dosimetry techniques that enhance the accuracy and effectiveness of radiation treatment.
Latest Patents
Aldweri's latest patents include a composition of polymer gel dosimeters specifically designed for radiation therapy. This invention introduces new compositions of tissue-equivalent three-dimensional polymer gel dosimeters based on acrylamide (AAm), N-isopropylacrylamide (NIPAM), N-(Hydroxymethyl)acrylamide (NHMA), diacetone acrylamide (DAAM), and N-Vinylcaprolactam (NVCL) monomer with ethylene glycol co-solvent. The dosimeter was subjected to irradiation with 6 and 15 MV linear accelerators at absorbed doses up to 10 Gy. The degree of polymerization of the five gels was investigated using the nuclear magnetic resonance (NMR) spin-spin relaxation rate (R) for water protons surrounding polymer formation. Additionally, the effects of additives, dose rate, radiation energy, and the stability of polymerization after irradiation were thoroughly examined on the dose response of the gels.
Another significant patent involves the method of making a radiochromic dosimeter using Calcein dye. This includes Calcein-PVA film and Calcein solution dosimeters, which are particularly useful for high-dose applications. Systematic evaluations of the dosimetric properties for these films have shown their utility as routine dosimeters in industrial radiation processing. The color bleaching of the CA-PVA film and CA solution increases gradually with absorbed doses ranging from 5-30 kGy for film and 0.25-1 kGy for solution. The dose sensitivity notably increases with higher concentrations of CA dye, while the response of the CA-PVA films is only slightly affected by relative humidity and temperature. The stability of these film dosimeters and solutions after irradiation is remarkably high, remaining stable for up to 30 days.
