Background:The clinical practicum provides an opportunity for students to apply and integrate classroom theory and clinical practice and competence effectively. In a teaching hospital, it is the responsibility of all staff to participate in clinical teaching and every interaction with a student constitutes a learning experience. The clinical teaching characteristics that are important to students and facilitate learning are not clearly defined in radiation therapy practice.
OH) for analysis. Total prostate volume, union and intersection volumes were determined. To assess similarity of prostate volumes between the CSRT and the RO, the DICE index was used. The index is a scale from zero to one with an index of zero indicating no overlap of contours and an index of one representing complete unity or overlap of contours. Results: The mean prostate volume for all 23 patients was 34.75cc vs. 37.33cc between the CSRT and the gold standard respectively. The mean DICE index value was 0.92 (range 0.82-0.95). The areas of greatest variability occurred at the base and apex of the prostate. Conclusions: This feasibility study found that there is high concordance between prostate delineation performed by an advanced practice CSRT and an RO. These early findings provide evidence that CSRTs are capable of accurately contouring prostate volumes on TRUS volume studies. Future work will describe the variability between all ROs performing prostate brachytherapy and the CSRT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
