    摘要: A system and method for optical lymph node mapping. The system is useful for guiding sentinel lymph node biopsy surgeries. A contrast agent that includes a fluorescent dye is injected near the site of a malignancy. The contrast agent drains into the lymphatic system, collecting in a sentinel node or nodes. The system utilizes one or more low-power continuous-wave lasers or light-emitting diodes modulated with a digital code sequence to probe the tissue suspected of containing the sentinel node. When the light is incident near the sentinel node, it will excite fluorescence from the dye. A portion of the scattered fluorescent light is captured with one or more photo-detectors. A correlation of the photo-detector signal and the digital code sequence is calculated to produce an estimate of the distribution of flight times for photons traveling from a given source to a given detector. The flight time distributions are used along with the measured amplitudes to reconstruct a map of contrast agent location within the tissue.

    摘要: A dynamic data distribution network (12) for use with a software package (10), which includes modules (14, 16, and 18) that produce data and modules (20, 22, 24, and 26) that consume data. The network includes source files (30) and sink files (32). Each data-consuming module contains one or more sink files, each of which serves as a buffer for one type of data used by the module. Each source file serves as a buffer for one type of data that is generated by a data-producing module. Each source file also contains a sink link table (40) that identifies the individual sink files, which serve as buffers for the data consumers that use that data. Whenever new data is generated, a data distribution task (34) initially stores the data in the associated source file and, then based on the contents of the sink link table, copies the data into the appropriate sink files associated with the data consumers that use the data. The data distribution function also informs the data consumers that new data are available in the sink file with which the data consumer is associated, enabling the data consumers to retrieve the data from the sink files.
