Characterization of a new radiochromic film (LD-V1) using mammographic beam qualities

Zeitschrift für Medizinische Physik
Purpose: Radiochromic film (RCF) is a detector that can obtain a two-dimensional dose distribution with high resolution; it is widely used in medical and industrial fields. Several types of RCFs exist based on their application.

Efficient Charge Transport in Zero‐Dimensional Perovskite for Ultrahigh‐Sensitivity X‐Ray Detection

Advanced Functional Materials, EarlyView.
A novel mono‐octahedral 0D Bi‐based Dpy3Bi2I12 perovskite strengthens the internal hydrogen bonds and forms a quasi‐2D lattice, exhibits exceptional charge transport and mobility, achieving high X‐ray sensitivity and ultralow‐dose imaging, and setting a new benchmark for 0D detector performance.

Procedural Outcome of Modern Percutaneous Coronary Intervention in Proximal Chronic Total Occlusions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Long‐term outcome in patients with chronic total occlusions (CTO) depends on the target vessel and proximity of the lesion. Aims To investigate of the target vessel was associated with procedural efficacy and safety in patients with proximal CTO lesions.

Patient Dose Optimisation of Abdominopelvic Protocols During X‐Ray Imaging

Journal of Medical Radiation Sciences, EarlyView.
This study evaluates organ doses in abdominopelvic radiography for both erect and supine positions, addressing dose optimisation concerns in Ghana. Using CalDose X and thermoluminescence dosimeters, organ doses and image quality were analysed, revealing significant dose reductions with optimised exposure parameters (70 kVp, 10 mAs, 110 cm FDD).

Air kerma strength characterization of a GZP6 Cobalt-60 brachytherapy source [PDF]

Reports of Practical Oncology & Radiotherapy, 2010
Task group number 40 (TG-40) of the American Association of Physicists in Medicine (AAPM) has recommended calibration of any brachytherapy source before its clinical use. GZP6 afterloading brachytherapy unit is a (60)Co high dose rate (HDR) system recently being used in some of the Iranian radiotherapy centers.In this study air kerma strength (AKS) of (

Impact of Ceiling Suspended Shield Size on Primary Operator Radiation Dose During Coronary Angiography and Intervention

Journal of Medical Radiation Sciences, EarlyView.
Reducing radiation exposure to staff performing coronary angiography and intervention is an occupational health and safety priority for hospitals. We demonstrate that a larger lead acrylic shield, with lead rubber pleats on the lower edge will reduce radiation exposure to the cardiologist performing the procedure by approximately 40%. We recommend that
