Primary Outcome Measures:
  • The hypothesis is that by using CBCT, the CTV to PTV margin can be reduced by approximately 50% (from 5 mm to 2.5 mm) and that this can reduce toxicity and allow radiotherapy dose escalation. [ Designated as safety issue: No ]

Enrollment: 30
Study Start Date: March 2007
Study Completion Date: September 2010
Primary Completion Date: February 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Cone Beam CT Device: PTV Reduction
The margin around the area to be treated with radiation is decreased due the image guidance of the cone beam CT

Detailed Description:

The general purpose of this study is to evaluate Kilovoltage (kv) Imaging, specifically the Cone-beam CT (CBCT) scan device, to assess the accuracy of radiation therapy treatment delivery for patients with head and neck neoplasms
