Evaluation of Surface Dose and Commissioning of Compensator-Based Total Body Irradiation
Conclusion: The commissioning of the compensator-based TBI technique was performed and its QA measurements were carried out. The Mayneord factor corrected PDD and measured PDD values were compared. The results are well within the clinical tolerance limit. This study concludes that 10 cm −20 cm is the optimal distance from the beam spoiler to phantom surface to achieve prescribed dose to the skin. (Source: Journal of Medical Physics)

Evaluating the impact of ionization chamber-specific beam quality correction factor in dosimetry of filtered and unfiltered photon beams
Conclusion: The measured absolute dose values by the ion chamber of a given make and model were found different due to the use of its theoretical and experimental kQ, Qo values. Furthermore, the variation in response of different pieces of ion chambers of the same make and model cannot be accounted for theoretically, and hence, the use of theoretical kQ, Qo data may introduce an inherent error in the estimation of absorbed dose to water. This necessitates the use of measured value of kQ, Qo for each ionization chamber. (Source: Journal of Medical Physics)

Reduction of Metal Artifacts Caused by Titanium Peduncular Screws in the Spine by Means of Monoenergetic Images and the Metal Artifact Reduction Software in Dual-Energy Computed Tomography
Conclusions: The VMR + MARS image reduces metal artifacts from titanium peduncular screws more than VMRs alone and CI. Furthermore, the VMR can decrease metal artifacts from a quantitative and a qualitative point of view. Combining information from VMRs and VMR + MARS images could be the best way to solve the issue of metal artifacts on computed tomography images. (Source: Journal of Medical Physics)

Quantitative comparison of dosimetric data between the indigenous baseplate and commercially available carbon fiber baseplate for 6 and 15 MV photon energy
Conclusions: The ID baseplate has shown acceptable dosimetric results and can be an economically viable alternative to the commercially available CF baseplates. The manufacturing cost of the ID baseplate was ten times cheaper than the CF baseplate. (Source: Journal of Medical Physics)

Conventional versus different hypofractionated radiotherapy dosage schedules in postmastectomy advanced breast cancer
Conclusion: Hypofractionated RT is a part of the typical treatment regimen for breast cancer nowadays. The major advantage is of convenience to the patients as it is completed the full course of RT in fewer sessions. With both conventional and hypofractionated radiation, the patient receives radiation 5 days a week. In the conventional regimen, though the schedule lasts for 5 weeks, whereas hypofractionation therapy is completed in 2 to 3 weeks. Local control wise both conventional and hypofractionated regimen is similar in locoregional control and toxicity. Therefore, hypofractionated RT should be practiced in cancer brea...

Normal tissue risk estimation using biological knowledge-based fuzzy logic in volumetric modulated Arc therapy of prostate cancer: Rectum
Conclusion: A new approach of two-level fuzzy logic may be suitable to estimate possible organ-at-risk (OAR) toxicity biologically without compromising tumor volume that includes both prostate target and OAR rectum deformation even at displacement standard errors of prostate ranging from 0 to 5 mm range which was considered in the present study. Using proposed simple and fast method, there is an interplay between volume-risk relationship and NTCP of OARs to judge real-time normal organ risk level or alter the treatment margins, particularly concern to individual factors such as comorbidities, genetic predisposition, and ot...

Assessment of Knowledge-Based Planning Model in Combination with Multi-Criteria Optimization in Head-and-Neck Cancers
Conclusion: MCO-based KBPM plans were superior to user plans in terms of OAR sparing and user need to spend more time to meet the model-based plan outcomes. Created KBPM planning is simple and efficient to generate estimate for OAR sparing to guide entry and intermittent planners to improve their clinical planning skills with lesser planning time. Python ESAPI is a powerful tool to extract plan parameters and quickly evaluate either individual or a cohort of plans. (Source: Journal of Medical Physics)
