Brief summary
Dosimetry efficacy of the hydrogel spacer.
Detailed description
Single arm study for evaluation of dosimetry following use of a commercially available hydrogel spacer implanted in up to 20 males who underwent radiotherapy treatment for prostate cancer. Study utilized pre and post gel insertion CT images to determine endpoints.
Interventions
Assessment of rectal dosimetry change from pre-insertion to post-insertion in subjects with prostate cancer who have undergone radiotherapy with a hydrogel spacer.
