Purpose: To find an integrated solution for plan evaluation with multiple dosimetric parameters in order to ensure quality of target dose coverage and sparing of organs collectively.
Materials And Methods: A mathematical logical expression called Plan Quality Index (PQI) was formulated. It includes two integrated indices 1.
Background: Radiotherapy plays an important role in the management of cancer. Although the improved technologies increase therapeutic index, different delivery techniques deliver different dose pattern to the healthy tissue within and outside treatment volume.
Objective: The objective of this study was to evaluate the low, intermediate, and high dose to healthy tissue within and outside the treatment volume and to find the relation between tumor volume and various doses received healthy tissue volume.
Article Synopsis
- The study aimed to assess the effect of the conformity index on the unified dosimetry index (UDI) scores between two radiation therapy techniques, IMRT and Rapid Arc, in 57 patients.
- The results indicated that while IMRT plans generally achieved a higher UDI score, Rapid Arc plans had a significantly better conformity index.
- When comparing the detailed indices, Rapid Arc showed a slightly better average dose gradient and homogeneity, but the UDI scores revealed significant differences based on the actual conformity index, emphasizing its impact in the evaluation of treatment plans.
