The effect of tomotherapy imaging beam output instabilities on dose calculation. Vrije Universiteit Brussel
A radiotherapy treatment plan is based on an anatomical 'snapshot' of the patient acquired during the preparation stage using a kVCT (kilovolt computed tomography) scanner. Anatomical changes will occur during the treatment course, in some cases requiring a new treatment plan to deliver the prescribed dose. With the introduction of 3D volumetric on-board imaging devices, it became feasible to use the produced images for dose recalculation. ...
The effect of different image reconstruction techniques on pre-clinical quantitative imaging and dual-energy CT Ghent University
Virtual monoenergetic micro-CT imaging in mice with artificial intelligence Ghent University KU Leuven
In vivo electrical conductivity imaging of animal tumor model at 7T using electrical properties tomography Ghent University
Quantification of liver fat in mice: comparing dual-echo Dixon imaging, chemical shift imaging, and 1H-MR spectroscopy KU Leuven
We evaluated dual-echo Dixon in-phase and out-of-phase (IP-OP), chemical shift imaging (CSI), and (1)H MRS (hydrogen MR spectroscopy) in estimating fat content (FC) in phantoms and in livers of mice. Phantoms were made according to the volume percentage of fat ranging from 0% to 100%. The three MR methods were performed to measure FC in phantoms and in livers of obese leptin-deficient (ob/ob), human BSCL2/seipin gene knockout (SKO), and ...
Super-resolution magnetic resonance imaging of the knee using 2-dimensional turbo spin echo imaging University of Antwerp
Objectives The purpose of this study was to assess the technical feasibility of 3-dimensional (3D) super-resolution reconstruction (SRR) of 2D turbo spin echo (TSE) knee magnetic resonance imaging (MRI) and to compare its image quality with conventional 3D TSE sampling perfection with application optimized contrast using different flip angle evolutions (SPACE) MRI. Materials and Methods Super-resolution reconstruction 2D TSE MRI and 3D TSE SPACE ...
Comparison of optical CT imaging versus NMR imaging for nPAG gel dosimetry Ghent University
Radiotherapy has evolved towards a more accurate technique of delivering a prescribed dose to the target volume. As a consequence, steep dose gradients in three dimensions occur near the edges of the target volume. Polymer gel dosimeters are able to record the integrated absorbed dose in three dimensions (3D). To read out the dose information of a 3D gel dosimeter we need a dedicated imaging technique. The aim of this study was to compare ...
The development of mathematical observers for optimization in breast imaging KU Leuven
Breast cancer screening in women aims to reduce cancer mortality rate by means of early detection and treatment. The screening is typically performed using a two-dimensional (2D) full-field digital mammography (FFDM) system, where the breast structure is captured in a single 2D projection. However the representation of three-dimensional (3D) breast tissue in 2D images causes a major drawback of this technique: normal tissue could mask a ...
