    摘要： This document discusses, among other things, an imaging guidewire that includes one or more optical fibers communicating light along the guidewire. At or near its distal end, one or more blazed or other fiber Bragg gratings (FBGs) directs light to a photoacoustic transducer material that provides ultrasonic imaging energy. Returned ultrasound is sensed by an FBG sensor. A responsive signal is optically communicated to the proximal end of the guidewire, and processed to develop a 2D or 3D image. In one example, the guidewire outer diameter is small enough such that an intravascular catheter can be passed over the guidewire. Techniques for improving ultrasound reception include using a high compliance material, resonating the ultrasound sensing transducer, using an attenuation-reducing coating and/or thickness, and/or using optical wavelength discrimination. Techniques for improving the ultrasound generating transducer include using a blazed FBG, designing the photoacoustic material thickness to enhance optical absorption. Techniques for distinguishing plaque or vulnerable plaque may be used to enhance the displayed image.

    摘要： An apparatus and method are disclosed for preparing electrically conductive traces on a circuit board using an additive technology. The traces are directly written in a serial process with each trace being able to be individually insulated. The apparatus includes an extrusion element for extruding a first material and a stage. The stage is for holding the extrusion element and the circuit board in relative proximity and for producing relative motion between the extrusion element and the circuit board in order to extrude the first material onto the surface of the circuit board along preselected paths to produce the electrically conductive traces. According to the method of invention, a first polymerizable material is extruded onto a circuit substrate support along preselected paths to form traces, and the first polymerizable material is polymerized, the first polymerizable material being conductive after polymerization. A circuit board for holding electrical components is disclosed which includes a circuit substrate support and a plurality of electrically conductive traces. The traces are adhered to the circuit substrate support between locations for the electrical components, the traces being formed of a polymer thick film by extrusion from an orifice onto the support along paths defining the location of the traces. Several embodiments of extrusion systems are described as are systems for milling and drilling boards to provide new manufactures of circuit boards.
