Reducing tomotherapy modulation beyond the gantry plateau saved almost no treatment time
The pre-plateau modulation factor preserved plan quality while further reduction created idle delivery time without meaningful efficiency gain.

No tested head phantom fully met cranial synthetic CT QA criteria
Skull-equivalent anatomy improved synthetic CT performance, but none of ten tested head phantoms satisfied all geometric, HU and dosimetric criteria.
Action-priority FMEA narrowed radiation therapy QA risks from 30 to seven
A severity-weighted action-priority framework identified the same seven highest RT workflow risks while avoiding 23 additional traditional FMEA flags.
uTPS produced deliverable Halcyon VMAT plans comparable with Eclipse
uTPS generated Halcyon VMAT plans with generally comparable dosimetry to Eclipse and greater than 97% gamma passing rates.
KROG 19-09 reveals major dose variation within intended breast nodal treatment groups
Substantial physician-dependent dose variation meant treatment-group assignment did not consistently reflect the dose actually delivered to regional nodes.
OCTAVIUS 4D achieved 98.3% gamma passing for MR-LINAC SBRT QA
Across 40 Unity SBRT plans, OCTAVIUS 4D achieved 98.3% mean local gamma passing with sub-degree angular agreement.
Generative AI is spreading across radiation therapy workflows, but validation remains the bottleneck
A scoping review maps generative AI across imaging, documentation, QA and decision support while emphasizing major safety and governance gaps.
Deep learning reduced combined truncation and metal artifacts in half-detector CBCT
HD-TMAR improved metal-region PSNR from 25.5 to 35.5 dB in simulated half-detector CBCT while preserving dental anatomy.
Audit logs measured artificial intelligence contour correction time with 0.93 concordance
Treatment-planning audit logs closely reproduced manual contour-edit timing and exposed major structure-specific differences in correction workload.
Eye tracking and imaging features predicted uncertainty in manual brain tumor contours
Behavioral and image-derived features explained 39% of interobserver contour uncertainty during manual brain tumor delineation.
Real-world brain MR-only implementation exposed frequent synthetic CT artifacts
Synthetic CT artifacts were common during brain MR-only implementation, highlighting workflow QA and patient-selection issues not captured by controlled validation.
Commercial AI synthetic CT showed good soft-tissue agreement but important high-density failures
AI synthetic CT preserved soft-tissue HU and geometry well, while bone, air interfaces and implanted devices remained important failure modes.
High-density shielding materials reduced modeled radiotherapy vault footprint by up to 34%
Alternative shielding materials reduced modeled linac vault area by 17–34% while remaining below the NCRP controlled-area dose goal.
Unshielded SunSILICON detector performed reliably for small-field photon dosimetry
The unshielded SunSILICON detector required only modest corrections in small fields, while the shielded version became unreliable below approximately 2 cm.
Radiotherapy 3D printing needs standardized quality assurance across institutions
Inter-centre material variability supports shared QA datasets and standardized acceptance criteria for clinical radiotherapy 3D printing.
