AbstractID: 12899 Title: Dosimetric Characterization of a Dedicated Breast Computed Tomography Clinical Prototype System
ID: 12899 Title: Dosimetric Characterization of a Dedicated Breast Computed Tomography Clinical Prototype System Purpose: To determine the radiation dosimetry characteristics of a dedicated breast computed tomography (BCT) clinical prototype system. Method and Materials: The relevant parameters of the BCT system were replicated in a Monte Carlo simulation program based on the Geant4 toolkit. To...
متن کاملGeneration of polychromatic projection for dedicated breast computed tomography simulation using anthropomorphic numerical phantom
Numerical simulations are fundamental to the development of medical imaging systems because they can save time and effort in research and development. In this study, we developed a method of creating the virtual projection images that are necessary to study dedicated breast computed tomography (BCT) systems. Anthropomorphic software breast phantoms of the conventional compression type were synt...
متن کاملUltrasound Tomography Evaluation of Breast Density
OBJECTIVES Ultrasound tomography (UST) is an emerging whole-breast 3-dimensional imaging technique that obtains quantitative tomograms of speed of sound of the entire breast. The imaged parameter is the speed of sound which is used as a surrogate measure of density at each voxel and holds promise as a method to evaluate breast density without ionizing radiation. This study evaluated the techniq...
متن کاملCone-beam Breast Computed Tomography: CT Density Does Not Reflect Proliferation Potential and Receptor Expression of Breast Carcinoma12
PURPOSE Recently, cone-beam breast computed tomography (CBCT) is established for the breast investigation. The purpose of the present study was to investigate possible associations between CBCT findings and histopathological features in breast cancer. METHODS Overall, 59 female patients, mean age of 64.6 years with histological proven breast cancer were included into the study. In all cases, ...
متن کاملGlandular dose in breast computed tomography with synchrotron radiation.
The purpose of this work is to provide an evaluation of the mean glandular dose (MGD) for breast computed tomography (CT) with synchrotron radiation in an axial scanning configuration with a partial or total organ volume irradiation, for the in vivo program of breast CT ongoing at the ELETTRA facility (Trieste, Italy). A Geant4 Monte Carlo code was implemented, simulating the photon irradiation...
