Autor: F. Alsanea, Yoshifumi Hojo, Sam Beddar, Chinmay Darne

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 939:16-21

Quality assurance detectors comprising cameras and a scintillator volume are of interest for use in spot scanning proton therapy due to its dynamic delivery. In this work, we aimed to image scanned proton beams with greater flexibility than is provid

Bilateral Lung and Liver Hydatid Cyst with Massive Hydropneumothorax: A Rare Case Report in Kuwait

Autor: Hamad F Alsanea, Ehab S. Imam, Derar Al Shehab, Ahmad E. Al-Mulla, Essa AlGhunaim

Publikováno v: Journal of Surgery and Research.

Bilateral lung and synchronous hydatid cyst is a unique presentation in a patient. It is endemic in some parts of the world, but it is rare in Kuwait. Hydatid cyst results from Echinococcus infection, and it affects between one and nine people in 10,

Image quality evaluation of projection- and depth dose-based approaches to integrating proton radiography using a monolithic scintillator detector

Autor: Rajesh Panthi, F. Alsanea, Irwin I. Tendler, Chinmay Darne, Daniel G. Robertson, Sam Beddar, Charles-Antoine Collins-Fekete

Publikováno v: Physics in medicine and biology. 66(14)

The purpose of this study is to compare the image quality of an integrating proton radiography system, composed of a monolithic scintillator and 2 digital cameras, using integral lateral-dose and integral depth-dose image reconstruction techniques. M

A proton imaging system using a volumetric liquid scintillator: a preliminary study

Autor: Chinmay Darne, Fada Guan, F. Alsanea, Daniel G. Robertson, David R. Grosshans, Tinsu Pan, Sam Beddar

Publikováno v: Biomed Phys Eng Express

With the expansion of proton radiotherapy for cancer treatments, it has become important to explore proton-based imaging technologies to increase the accuracy of proton treatment planning, alignment, and verification. The purpose of this study is to

A real‐time method to simultaneously measure linear energy transfer and dose for proton therapy using organic scintillators

Autor: F. Alsanea, François Therriault-Proulx, Gabriel O. Sawakuchi, Sam Beddar

Publikováno v: Med Phys

PURPOSE: Currently, no detectors are capable of simultaneously measuring dose and linear energy transfer (LET) in real time. In this study, we evaluated the feasibility of exploiting the difference in the response of various organic plastic scintilla

Exradin W1 plastic scintillation detector for in vivo skin dosimetry in passive scattering proton therapy

Autor: Narayan Sahoo, L. Wootton, F. Alsanea, Rajat J. Kudchadker, Sam Beddar, Usama Mahmood

In vivo skin dosimetry is desirable in passive scattering proton therapy because of the possibility of high entrance dose with a small number of fields. However, suitable detectors are needed to determine skin dose in proton therapy. Plastic scintill
