Some embodiments facilitate 3D-printing of flattened coil devices having low aspect ratio between their lengths along their magnetic axes and their widths perpendicular thereto.

Abstract: A position sensor for measuring signals indicative of location and/or orientation a catheter's distal end, and a method of fabrication thereof are disclosed. The position sensor includes a flexible circuit board (FCB) and at least three surface mount coil devices (SMD coils) arranged thereon for sensing different aspects of one or more magnetic fields, which are indicative of the location and/or orientation of the catheters distal end. The FCB is furnished at the sensor in folded/rolled state such that the magnetic flux axes of at least three of the SMD coils are not co-planar to thereby enable utilizing signals measured thereby determine the at least one of the orientation and location of the sensor relative to one or more magnetic field sources.

Abstract: A method for detecting single photons of high energy radiation using a detector comprising an array of pixels, each pixel including a charge receptive substrate. The method includes the operations of capturing high energy photons with the pixel array, collecting the charges generated in each pixel by the charge receptive substrate of that pixel, reading out the collected charges and analyzing the read out charges. In addition, a system for detecting single photons of high energy radiation is described.

The system further includes low noise electronics for reading out the charges generated by high energy photons when the latter interact with the film. Additionally, the system includes a data processor in communication with the low noise electronics.
