This paper presents Platener, a system that allows quickly fabricating intermediate design iterations of 3D models, a process also known as low-fidelity fabrication. Platener achieves its speed-up by extracting straight and curved plates from the 3D model and substituting them with laser cut parts of the same size and thickness. Only the regions that are of(More)
Low-fidelity fabrication systems speed up rapid prototyping by printing intermediate versions of a prototype as fast, low-fidelity previews. Only the final version is fabricated as a full high-fidelity 3D print. This allows designers to iterate more quickly-achieving a better design in less time. Depending on what is currently being tested, low-fidelity(More)
In this paper, a novel reconstruction method is presented for Near Infrared (NIR) 2-D imaging to recover optical absorption coefficients from laboratory phantom data. The main body of this work validates a new generation of highly efficient reconstruction algorithms called " Globally Convergent Method " (GCM) based upon actual measurements taken from(More)
High spatial resolution magnetic resonance images of the shoulder were obtained in axial, sagittal and coronal orientations using a 1.5 T imaging system and anatomically shaped, wrap-around surface coils. Variations in scapular position induced by patient positioning change the relationship of the planes to the shoulder anatomy and make reproducibility of(More)
Surface coils are specially designed radio-frequency receiver coils used for magnetic resonance imaging (MRI) of special anatomical regions, for instance, orbit and knee joint, with a higher spatial resolution than that obtained with conventional MRI techniques. They are designed to fit the anatomical part to be imaged, thus enabling a coil to be placed in(More)
