Article Synopsis
- An independent dosimetry audit for proton therapy delivery is recommended to ensure consistent treatments across different centers; this study outlines a methodology developed through collaboration between MedAustron and the National Physical Laboratory.
- The auditing process involved using phantoms—one homogeneous and one anthropomorphic—dosed with ionization chambers, alanine pellets, and radiochromic films to evaluate treatment accuracy under different scenarios.
- Results showed that measurements using alanine pellets and ionization chambers were consistent, with minimal deviations from predicted doses; the successful application of this audit method at five proton centers suggests it could be valuable for future clinical trial credentialing in proton beam therapy.
Purpose: To propose a magnetic resonance imaging (MRI) quality assurance procedure that can be used for multicenter comparison of different MR scanners for quantitative diffusion-weighted imaging (DWI).
Materials And Methods: Twenty-six centers (35 MR scanners with field strengths: 1T, 1.5T, and 3T) were enrolled in the study.
Lithium 2,2,6,6-tetramethylpiperidide (LTMP)-induced intramolecular cyclopropanation of unsaturated terminal epoxides provides an efficient and completely stereoselective entry to bicyclo[3.1.0]hexan-2-ols and bicyclo[4.
