متن کاملEvaluation of accuracy of 3D reconstruction images using multi-detector CT and cone-beam CT
PURPOSE This study was performed to determine the accuracy of linear measurements on three-dimensional (3D) images using multi-detector computed tomography (MDCT) and cone-beam computed tomography (CBCT). MATERIALS AND METHODS MDCT and CBCT were performed using 24 dry skulls. Twenty-one measurements were taken on the dry skulls using digital caliper. Both types of CT data were imported into O...
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 کاملAccuracy of co-registration of planning images with Cone Beam CT images
Leksell Gamma Knife® IconTM with integrated Cone Beam CT (CBCT) system provides increased workflow flexibility with e.g. planning on frameless images and subsequent frameless dose delivery. The stereotactic reference is given by the CBCT images taken prior to treatment. Co-registration of the planning image volume with the CBCT volume gives the transformation mapping of the planned isocenter po...
متن کاملShading correction for cone-beam CT in radiotherapy: Validation of dose calculation accuracy using clinical images
Cone-beam CT (CBCT) images are routinely acquired to verify patient position in radiotherapy (RT), but are typically not calibrated in Hounsfield Units (HU) and feature non-uniformity due to X-ray scatter and detector persistence effects. This prevents direct use of CBCT for re-calculation of RT delivered dose. We previously developed a prior-image based correction method to restore HU values a...
