Article Synopsis
- - The study investigates the use of Slot-scan digital radiography (SSDR) with detachable scatter grids and copper filters for low-dose whole-spine imaging, focusing on determining optimal imaging parameters.
- - Various tube voltages and exposure times were tested with different beam-hardening (BH) filter thicknesses to find settings that maintain image quality while minimizing radiation exposure.
- - Results showed that using a 0.3-mm BH filter allowed for a significant reduction in radiation dose (up to 79%) without compromising the quality of whole-spine images.
Article Synopsis
- The study investigates the effectiveness of HMD-based virtual reality coaching systems (HMD-VRC) for teaching radiography skills, noting that previous evaluations relied solely on questionnaires.
- It involved 30 first-year radiology students in Japan, comparing those trained with HMD-VRC to those using traditional equipment, leading to mixed results in skill proficiency.
- The findings indicate that while some skills were comparable, there was a significant drop in proficiency related to palpation and patient interaction, suggesting HMD-VRC may be less effective than hands-on training in certain areas.
