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

OTHERObservation
