Optimal slice thickness for object detection with longitudinal partial volume effects in computed tomography
Longitudinal partial volume effects (z-axial PVE), which occur when an object partly occupies a slice, degrade image resolution and contrast in computed tomography (CT). Z-axial PVE is unavoidable for subslice objects and reduces their contrast according to their fraction contained within the slice. This effect can be countered using a smaller slice thickness, but at the cost of an increased im...
متن کاملEffect of Slice Thickness on the Accuracy of Linear Measurements Made on Cone Beam Computed Tomography Images (InVitro
Objective: Cone beam computed tomography (CBCT) is applied for the imaging of the maxillofacial and dental structures, particularly for surgical treatments and dental implants. The aim of this study was to assess the effect of slice thickness on the accuracy of CBCT linear measurements. Methods: In this diagnostic accuracy study, forty-two titanium pins with the same dimensions were inserted...
متن کاملthe effect of voxel size on the measurement of mandibular thickness in cone-beam computed tomography
background: cone-beam computed tomography (cbct) is a new imaging technology that has been widely used in implantology, oral and maxillofacial surgery and orthodontics. this method provides 3-d images that are composed of voxel, which is the smallest image unit, and determines image resolution. smaller voxel is associated with the higher resolution and also greater radiation exposure. this stud...
