1. Cost and benefits of cone beam computed tomography : for maxillary canines with eruption disturbance
Abstract : I tandvården finns allt fler metoder för prevention, diagnostik och behandling. Eftersom resurserna är begränsade bör den metod väljas där nyttan uppväger kostnaden. Idag saknas dock vetenskapliga belägg gällande kostnadseffektivitet för undersökning med Cone Beam Computed Tomography (CBCT). READ MORE

2. Maxillofacial cone beam computed tomography (CBCT) : aspetcs on optimisation
Abstract : Inom odontologisk såväl som inom medicinsk radiologi sker en snabb utveckling av nya tekniker. Nya metoder för att kunna diagnosticera och följa sjukdomsförlopp över tid introduceras. Cone-Beam Computed Tomography (CBCT) är en sådan ny teknik, som introducerades inom odontologin under sent 1990-tal. READ MORE

3. Cone Beam Computed Tomography - radiation dose and image quality assessments
Abstract : Diagnostic radiology has undergone profound changes in the last 30 years. New technologies are available to the dental field, cone beam computed tomography (CBCT) as one of the most important. READ MORE

4. Combining analytical and iterative reconstruction in helical cone-beam CT
Abstract : Contemporary algorithms employed for reconstruction of 3D volumes from helical cone beam projections are so called non-exact algorithms. This means that the reconstructed volumes contain artifacts irrespective of the detector resolution and number of projection angles employed in the process. READ MORE

5. Problems and experiments in cone-beam tomography
Abstract : Two-dimensional detectors for cone-beam exposure are now introduced in medical as well as industrial computer tomography. This thesis starts with a review of basic 2D reconstruction algorithms and the first proposal for cone-beam tomography due to Feldkamp et al.Exact reconstruction is possible only if complete projection data are avail able.
