Small dose monitor based on silicon-carbide diodes for FLASH radiotherapy. [PDF]

Med Phys
Abstract Background The FLASH biological effect in radiotherapy has been observed to appear at ultra‐high dose rates UHDR (>$>$40 Gy/s), where the accurate dosimetry at such high rates is still a challenge. Purpose A new 4 ×$\times$ 4 array of SiC‐based detectors (1 mm diameter, 2.2 mm pitch) is proposed for dosimetry in UHDR, as well as the ...

Challenges in personal and clinical dosimetry using Li2B4O7 and MgB4O7 as TLD and OSLD

Brazilian Journal of Radiation Sciences, 2022
Thermoluminescent (TLD) and optically stimulated luminescent dosimeters (OSLD) are essential in radiation dosimetry. Such dosimeters can be easily transported due to their small size and can be used in in vivo dosimetry and anthropomorphic simulations ...

Quantifying stent-induced dose perturbations in intravascular brachytherapy using 3D- printed phantoms and film dosimetry. [PDF]

J Appl Clin Med Phys
Abstract Background Coronary artery disease (CAD), the leading cause of death worldwide, is the narrowing of coronary arteries due to atherosclerotic plaque buildup. A common treatment for CAD is percutaneous coronary intervention (PCI), often involving stent placement. However, a common complication or in‐stent restenosis (ISR) can occur in 10%–20% of

Assessment of dose reliability in radiotherapy practices in Türkiye: A multicenter study. [PDF]

J Appl Clin Med Phys
Abstract Background Dose accuracy in radiotherapy is crucial for treatment outcomes and patient safety. Ensuring dose accuracy allows for effective targeting of tumors while protecting surrounding healthy tissues. The quality assurance programs implemented worldwide by the International Atomic Energy Agency (IAEA) and the World Health Organization (WHO)
