Computed Tomography (CT) and Magnetic Resonance (MR) imaging techniques have become an important role in diagnosing the vascular diseases. Before a clinical trial of the newly developed techniques, it is essential to evaluate them on a phantom. However, there is no existing arterial A Dynamic Arterial Tree Phantom for studies 89 tree phantom that serves for flood flows. To that end, we design a...

objectives: bone quality and quantity assessment is one of the most important steps in implant treatment planning. different methods such as computed tomography (ct) and recently suggested cone beam computed tomography (cbct) with lower radiation dose and less time and cost are used for bone density assessment. this in vitro study aimed to compare the tissue density values in hounsfield units (...

introduction: computed tomography (ct) and cone-beam ct (cbct) are valuable diagnostic aids for many clinical applications. this study was designed to compare the gray scale value (gsv) and hounsfield unit (hu) of selected dental materials and various hard tissues using ct or cbct. methods and materials: three samples of all test materials including amalgam (am), composite resin (cr), glass ion...

The Geant4 Application for Emission Tomography (GATE) is an advanced open-source software dedicated to Monte-Carlo (MC) simulations in medical imaging involving photon transportation (Positron emission tomography, single photon emission computed tomography, computed tomography) and in particle therapy. In this work, we extend the GATE to support simulations of optical imaging, such as biolumine...
