Optical tomography of a realistic neonatal head phantom.
We have begun clinical trials of optical tomography of the neonatal brain. To validate this research, we have built and imaged an anatomically realistic, tissue-equivalent neonatal head phantom that is hollow, allowing contrasting objects to be placed inside it. Images were reconstructed by use of two finite-element meshes, one generated from a computed tomography image of the phantom and the o...
متن کاملModeling Time Resolved Light Propagation Inside a Realistic Human Head Model
Background: Near infrared spectroscopy imaging is one of the new techniques used for investigating structural and functionality of different body tissues. This is done by injecting light into the medium and measuring the photon intensity at the surface of the tissue.Method: In this paper the different medical applications, various imaging and simulation techniques of NIRS imaging is described. ...
متن کاملEvaluation of a constructed head phantom response in comparison with RANDO head phantom in the same gamma field
Human tissue equivalent phantoms are widely used in medicine. They are used for dosimetry, calibration of medical devices, and quality control of radiotherapy equipment, as well as training students. Regarding to development of radiotherapy techniques for treatment of cancers and also development of educational centers in the country, the human equivalent phantoms are needed. Several phantoms h...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Design and fabrication of a realistic anthropomorphic heterogeneous head phantom for MR purposes
OBJECTIVE The purpose of this study is to design an anthropomorphic heterogeneous head phantom that can be used for MRI and other electromagnetic applications. MATERIALS AND METHODS An eight compartment, physical anthropomorphic head phantom was developed from a 3T MRI dataset of a healthy male. The designed phantom was successfully built and preliminarily evaluated through an application tha...
