Use of Cone Beam Kilovaltage Imaging in Patients Receiving Radiation Therapy for Head and Neck Cancer
To evaluate the use of cone beam computed tomography in treating head and neck to hopefully reduce side effects
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.
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.
The primary aim of this study is to investigate the use of cone beam computed tomography (CBCT) for breast imaging in the diagnostic setting by providing a compelling body of evidence inco...
The primary aim of this study is to continue the investigation of cone beam computed tomography (CBCT) for breast imaging already underway in the diagnostic setting by providing a compelli...
This study is designed to investigate whether daily images of the pelvis and bladder using a device called a cone beam CT scanner will help to increase the accuracy of radiotherapy treatme...
The purpose of this study is to use cone-beam CT scans to more accurately position the tumor during radiation and to see whether this method is more effective than the standard method of u...
This study is conducting a comparison of chest x-ray (CXR) and minimum dose thoracic CT (MnDCT) in the detection of lung nodules (metastases) in patients with head and neck carcinoma.
BACKGROUND: Patients with a first head and neck carcinoma have a high risk of successive neoplasms, many of which appear again in the head and neck. Second head and neck tumors have a poorer prognosis...
Stroke from cardiac sources is a major cause of cerebral infarctions and ischemia. Cardiac sources of stroke include intracardiac thrombus, right-to-left shunts, tumors, and slow-flow states resulting...
Increasingly stringent guidelines for the use of cone-beam computed tomography (CBCT).
Objective: The aim of this study was to evaluate the frequency of enamel pearls according to population, sex and tooth groups on Cone-Beam Computed Tomography (CBCT) or Dental Volumetric Tomography (D...
The purpose of this study was to investigate the possible effects of section thickness on volume estimations obtained by cone beam computed tomography. Intraosseal cavities representing bone defects o...
