The influence of patient positioning and immobilization equipment on MR image quality and image registration in radiation therapy
CONCLUSION: The image quality reduction in the RT setup was due to the imaged region's anatomy and its position relative to the applied coil. Furthermore, optimizing the pulse sequence is crucial for MR imaging in RT applications. Although the use of immobilization equipment may decrease the image quality in the RT setup, it does not affect organ delineation, and the image quality is still satisfactory for this purpose. Also, the use of immobilization equipment in the RT setup has increased registration accuracy.PMID:37716368 | DOI:10.1002/acm2.14162

Deep learning in MRI-guided radiation therapy: A systematic review
J Appl Clin Med Phys. 2023 Sep 15:e14155. doi: 10.1002/acm2.14155. Online ahead of print.ABSTRACTRecent advances in MRI-guided radiation therapy (MRgRT) and deep learning techniques encourage fully adaptive radiation therapy (ART), real-time MRI monitoring, and the MRI-only treatment planning workflow. Given the rapid growth and emergence of new state-of-the-art methods in these fields, we systematically review 197 studies written on or before December 31, 2022, and categorize the studies into the areas of image segmentation, image synthesis, radiomics, and real time MRI. Building from the underlying deep learning methods,...

Shallow kinetics induced by a metronome (SKIM): A novel contactless respiratory motion management
CONCLUSION: Compared with FB, SKIM can significantly reduce respiratory motion magnitude of thoracic targets. The difference in maximum motion reduction in the overall vector norm, S-I, and A-P directions was significant (p = 0.033, 0.042, 0.011). Our proposed method can be an excellent practical alternative to conventional compression due to its flexibility and ease of implementation.PMID:37672210 | DOI:10.1002/acm2.14147

Deep learning-based detection and classification of multi-leaf collimator modeling errors in volumetric modulated radiation therapy
CONCLUSIONS: We demonstrated that the deep learning-based models could feasibly detect and classify TF and DLG errors in VMAT dose distributions, depending on the magnitude of the error, treatment site, and the degree of mimicked measurement doses.PMID:37633834 | DOI:10.1002/acm2.14136
