Introduction: Cone-beam CT (CBCT) is an imaging system which offers three-dimensional (3D), multiplanar images and has many advantages over computed tomography (CT) including shorter acquisition times for the resolution desired in dentistry, lower radiation dose to the patient, reasonable price and higher spatial resolution but CBCT scanners are unable to display actual Hounsf...
OBJECTIVE The VoxTox study, linking delivered dose to toxicity requires recalculation of typically 20-37 fractions per patient, for nearly 2000 patients. This requires a non-interactive interface permitting batch calculation with multiple computers. METHODS Data are extracted from the TomoTherapy(®) archive and processed using the computational task-management system GANGA. Doses are calculat...
Objective: Computed tomography (CT) is an often-used diagnostic imaging tool during the evaluation of cervical spine pathology. CT scan can provide one’s bone density by measuring Hounsfield’s unit. In anterior discectomy and fusion (ACDF) surgeries, may play important role as it relate to non-union. Therefore, consideration unit sub-axial vertebral body important, especially multi-level ACDF.M...
