摘要： A method for segmenting coronary vessels in digitized cardiac images includes providing a digitized cardiac image, providing a seed point in the image, selecting a volume-of-interest about the seed point, performing a local segmentation in the volume-of-interest, including initializing a connected component with the seed point and a threshold intensity value to the intensity of the seed point, adding a point to the connected component if the point is adjacent to the connected component and if the intensity of the point is greater than or equal to the threshold value, lowering the threshold intensity value, and computing an attribute value of the connected component, wherein if a discontinuity in the attribute value is detected, the local segmentation is terminated, wherein a local segmentation mask of a vessel is obtained.

摘要： Efficient fluorescence detection is achieved by optically guiding fluorescence light generated by color centers within a sample to photodetectors outside the sample. A fluorescence detection system may use a sample containing one or more fluorescence color centers that emit fluorescent light when irradiated with excitation light from an optical source. The sample has an index of refraction greater than its surrounding medium. The sample may include one or more output faces and further include at least two opposing faces configured to internally reflect the fluorescent light emitted by the fluorescent color centers, and to optically guide the emitted fluorescent light to the one or more output faces. The fluorescence detection system may include one or more optical detector configured to receive fluorescent light emitted through the one or more output faces, and a microwave source configured to manipulate the electronic spin of the fluorescent color centers.
