Use of Cone Beam Kilovaltage Imaging in Patients Receiving Radiation Therapy for Head and Neck Cancer
Summary
To evaluate the use of cone beam computed tomography in treating head and neck to hopefully reduce side effects
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

Medical and Biotech [MESH] Definitions
Cone-beam Computed Tomography
Computed tomography modalities which use a cone or pyramid-shaped beam of radiation.
Spiral Cone-beam Computed Tomography
Modality of computed tomography in which the patient is irradiated in a spiral path around the body with a cone or pyramid-shaped beam.
Tomography, Spiral Computed
Computed tomography where there is continuous X-ray exposure to the patient while being transported in a spiral or helical pattern through the beam of irradiation. This provides improved three-dimensional contrast and spatial resolution compared to conventional computed tomography, where data is obtained and computed from individual sequential exposures.
Neck Dissection
Dissection in the neck to remove all disease tissues including cervical LYMPH NODES and to leave an adequate margin of normal tissue. This type of surgery is usually used in tumors or cervical metastases in the head and neck. The prototype of neck dissection is the radical neck dissection described by Crile in 1906.
Tomography, X-ray Computed
Tomography using x-ray transmission and a computer algorithm to reconstruct the image.
