20110291025 | FLOW CYTOMETRY ANALYSIS ACROSS OPTICAL FIBER - An apparatus and method for analyzing a fluid with particle analytes, where the fluid is fed through a passageway within an optical fiber and excitation light is guided by the optical fiber across the passageway and intersects the fluid therein. The optical core is made multimode and is adapted to shape the excitation light with a uniform spatial illumination over a cross-section of the optical core and the passageway is configured relative to the optical core such that the particle analytes are exposed to substantially equal excitation light while circulating in the passageway. | 12-01-2011 |
20130342837 | METHOD AND FLOW CELL FOR CHARACTERIZING PARTICLES BY MEANS OF NON-GAUSSIAN TEMPORAL SIGNALS - The present disclosure relates to the field characterization of particles in a sample solution. More specifically, the present disclosure relates to a flow cell and a method for characterizing particles by means of collected non-Gaussian temporal signals. The present flow cell and method rely on an excitation fiber with a channel. The excitation fiber has a core for transporting an excitation light generated by a light source, and defines a channel through a portion of its core. The channel of the excitation fiber directs a flow of the sample solution. The excitation fiber, the channel and collection fibers characteristics are selected, proportioned and positioned to generate collected light with a non-Gaussian temporal intensity profile. | 12-26-2013 |

20100130853 | SYSTEM FOR TRACKING OBJECT - In one embodiment, a tracking system for tracking an object positioned inside the body of a patient is provided. The tracking system comprises a reference sensor, the reference sensor comprising at least one of a transmitter, a receiver and a transceiver, a first tracker sensor coupled to a first object, a second tracker sensor coupled to a second object and tracker electronics coupled to the reference sensor and each of the tracker sensors. The tracker electronics is configured to determine position and orientation of each of the tracker sensors relative to the reference sensor based on the relationship between the reference sensor and each of the tracker sensors. Further, each of the tracker sensors is one of a transmitter, a receiver and a transceiver. | 05-27-2010 |

20120328072 | Hybrid Multi-Row Detector and Flat Panel Imaging System - A system and a method for acquiring image data of a subject with an imaging system are provided. The system can include a gantry that completely annularly encompasses at least a portion of the subject, and a source positioned within the gantry. The source can be responsive to a signal to output at least one pulse. The system can include a multi-row detector positioned within the gantry. The multi-row detector can be in alignment with the source and sets multi-row detector data based on the detected at least one signal. The system can include a flat panel detector positioned within the gantry. The flat panel detector can in alignment with the source and sets flat panel detector data based on the detected at least one signal. The system can include an image acquisition control module that determines which of the multi-row detector and the flat panel detector to use. | 12-27-2012 |
