Optimizing Novel Inorganic Scintillation Detectors for Applications in Medical Physics

A novel QA phantom based on scintillating fiber ribbons with implementation of 2D dose tomography for small‐field radiotherapy

“…Like other plastic detecting systems, 6,24,25 our proposed detector has the advantage of being water equivalent with lower energy dependence and dose perturbations, in comparison with inorganic scintillating detectors. 13,14,28 These results on the phantom prototype confirm the feasibility of developing systems based on waterequivalent scintillating ribbons for small-field QA. They are in-line with the state of the arts and compare well with the performances achieved by QA systems based on a high spatial resolution diode array.…”

Highly Sensitive Direct‐Conversion Vacuum Flat‐Panel X‐Ray Detectors Formed by Ga2O3‐ZnO Heterojunction Cold Cathode and ZnS Target and their Photoelectron Multiplication Mechanism

“…[1,2] The modern mainstream indirect-conversion X-ray detection systems use an efficient scintillator (such as Gd 2 O 2 S:Tb [3] and (Zn,Cd)S:Ag [4] ), and have been applied in practical radiation therapy applications. [5,6] However, the indirect-conversion X-ray detectors have drawbacks of optical crosstalk and long luminance lifetime, thus, the researchers propose progressive direct-conversion X-ray detection systems aiming to realize high spatial resolution and low dose X-ray detection. [7][8][9] So far, the a-Se photo-using ZnO NW vacuum diode connected with HgI 2 crystal were proposed to achieve high sensitivity owing to the high X-ray absorption coefficient of HgI 2 and high operating electric field of vacuum diode.…”
