摘要： A camera attachment for measuring a temperature of a surface, and related methods of measuring the temperature of the surface, employ a temperature reactive material that is thermally coupled with the surface and imaged to provide image data of the temperature reactive material that is analyzed to measure the temperature. A camera attachment for measuring a temperature of a surface includes a distal surface configured to be thermally coupled with the surface, a frame configured to be coupled with a camera that has a field of view, and a temperature reactive material coupled with the frame and thermally coupled with the distal surface. The frame positions the temperature reactive material within the field of view of the camera so that an image captured by the camera includes at least a portion of the temperature reactive material.

摘要： In one embodiment of the invention, a semiconductor optical amplifier (SOA) in a laser ring is chosen to provide low polarization-dependent gain (PDG) and a booster semiconductor optical amplifier, outside of the ring, is chosen to provide high polarization-dependent gain. The use of a semiconductor optical amplifier with low polarization-dependent gain nearly eliminates variations in the polarization state of the light at the output of the laser, but does not eliminate the intra-sweep variations in the polarization state at the output of the laser, which can degrade the performance of the SS-OCT system.

摘要： A method and apparatus of automatically locating in an image of a blood vessel the lumen boundary at a position in the vessel and from that measuring the diameter of the vessel. From the diameter of the vessel and estimated blood flow rate, a number of clinically significant physiological parameters are then determined and various user displays of interest generated. One use of these images and parameters is to aid the clinician in the placement of a stent. The system, in one embodiment, uses these measurements to allow the clinician to simulate the placement of a stent and to determine the effect of the placement. In addition, from these patient parameters various patient treatments are then performed.
