While dosimetric accuracy in treatment planning system TPS is well quantified, the variability in volume estimation is uncertain due to reconstruction algorithm that is investigated in this study. For a better experience, use the Read by QxMD app. Comparative study of old and new versions of treatment planning system using dose volume histogram indices of clinical plans. However, the customer is provided less inner details about changes in the new software version. The FDG avid tumour volume, MTV50, was dose escalated in silico by intensity modulated radiotherapy from the standard An efficient and reliable 3D planning system, ROPS, was used for verifying the accuracy of treatment plans and treatment plan parameters Phys Med Biol.

In the present study, four commercial dental implants were used: pure titanium, titanium alloy Ti-6Al-4Vamalgam, and crown The results of this study are presented in this paper.
The purpose of this study was to compare the performance of different commercial quality assurance QA systems for the pretreatment verification plan of stereotactic body radiotherapy SBRT with volumetric arc therapy VMAT technique using a flattening-filter-free beam.
A comparative study of identical VMAT plans with and without jaw tracking technique. Stereotactic body radiation therapy patient specific quality assurance using a two-dimensional array at extended source to surface distance. On the basis of identical plans, this study aims to investigate the dosimetric impact of jaw tracking on the volumetric-modulated arc therapy VMAT plans.
