1. Metal artifacts in computed tomography : impact of reduction methods on image quality and radiotherapy treatment planning
Abstract : Degradation of image quality by metal artifacts is a common problem in computed tomography (CT) imaging, which can limit the diagnostic value of a CT examination and also introduce inaccuracies in radiotherapy (RT) treatment planning. In recent years, commercial metal artifact reduction (MAR) methods have been launched by several CT vendors. READ MORE

2. Computed tomography in endodontic decision making
Abstract : Computed tomography has been used in dentistry as a complement to two-dimensional (2D) imaging since the 1980s. The advent of cone beam computed tomography (CBCT), a more modern computed tomog-raphy technique, meant a revolution in dento-maxillofacial imaging due to sharper images, with less radiation and at a lower cost than with mul-ti-slice computed tomography (MSCT), i.

3. Computed tomography of sawlogs : knot detection and sawing optimization
Abstract : Branches on trees introduce defects on sawn timber called knots. By scanning sawlogs using computed tomography, knots can be detected and accounted for so that the sawing process can be optimized with respect to outgoing product value. READ MORE
