A radiotherapy community data-driven approach to determine which complexity metrics best predict the impact of atypical TPS beam modeling on clinical dose calculation accuracy
CONCLUSION: Extreme values for MLC offset and MLC transmission beam modeling parameters were found to most substantially impact the dose distribution of clinical plans and careful attention should be given to these beam modeling parameters. The mean MLC Gap and TGi complexity metrics were best suited to identifying clinical plans most sensitive to beam modeling errors; this could help provide focus for clinical QA in identifying unacceptable plans.PMID:38427776 | DOI:10.1002/acm2.14318 (Source: Journal of Applied Clinical Medical Physics)

A novel AP/PA total body irradiation technique using abutting IMRT fields at extended SSD
CONCLUSIONS: We have developed a promising TBI technique using abutting IMRT fields at extended SSD. The patient is in a comfortable recumbent position with good reproducibility and less motion during treatment. An additional benefit of this technique is that full 3D dose distribution is available from the TPS with a DVH summary for organs of interest. The technique allows precise sparing of lungs and kidneys and can be executed in any linac room.PMID:38425126 | DOI:10.1002/acm2.14213 (Source: Journal of Applied Clinical Medical Physics)

The use of dose surface maps as a tool to investigate spatial dose delivery accuracy for the rectum during prostate radiotherapy
CONCLUSION: DSMs enabled spatial investigations of planned and delivered doses can uncover associations with interfraction motion that are otherwise masked in DVHs. Investigations of dose delivery accuracy in radiotherapy may benefit from using DSMs over DVHs for certain organs such as the rectum.PMID:38425148 | DOI:10.1002/acm2.14314 (Source: Journal of Applied Clinical Medical Physics)

Technical note: A simple method for patient-specific quality assurance for lateral targets on a 1.5 T MR-Linac
J Appl Clin Med Phys. 2024 Mar 1:e14323. doi: 10.1002/acm2.14323. Online ahead of print.ABSTRACTThe Elekta Unity magnetic resonance (MR) linac is limited to longitudinal couch motion and a sagittal-only laser, which restricts the ability to perform patient-specific quality assurance (PSQA) intensity-modulated radiotherapy (IMRT) measurements for very lateral targets. This work introduces a simple method to perform PSQA using the Sun Nuclear ArcCheck-MR phantom at left and right lateral positions without additional equipment or in-house construction. The proposed setup places the center of the phantom 1.3 cm vertical and 12...

Efficacious patient-specific QA for Vertebra SBRT using a high-resolution detector array SRS MapCHECK: AAPM TG-218 analysis
CONCLUSION: Our findings suggest that universal TG-218 limits may not be suitable for vertebra SBRT PSQA. This study demonstrates that SRSMC is a viable tool for vertebra SBRT PSQA, supported by TG-218 implementation of process-based tolerance and action limits.PMID:38414322 | DOI:10.1002/acm2.14276 (Source: Journal of Applied Clinical Medical Physics)

Performance characteristics of the 5-ring GE Discovery MI PET/CT scanner using AAPM TG-126 report
CONCLUSION: These results show that the 5-ring GE Discovery MI PET/CT scanner testing using TG-126 is reproducible and has similar results to NEMA NU 2-2012 tests where applicable. We hope these results start to form the basis to compare PET/CT systems using TG-126.PMID:38415897 | DOI:10.1002/acm2.14315 (Source: Journal of Applied Clinical Medical Physics)
