    摘要: Inorganic semiconducting materials such as silicon are used as a host matrix in which quantum dots reside to provide a radiation detector or energy converter. The quantum dot material may be disposed by incorporating materials sensitive to neutron detection such as boron-containing compounds, or the use of methods such as chemical vapor deposition or atomic layer deposition to insert the quantum dot material. Electrodes may be extended deep into the host matrix material to improve efficiency. Likewise, the host matrix may be machined to create pores in the matrix material. Further, amplification and signal-processing structures may be used in close proximity to the radiation-sensitive region of the device.

    摘要: A magnetic field generator includes a power source and a segmented or un-segmented coil connected to the power source to generate a time-varying magnetic field. Energy is applied to the coil so that the coil generates a time-varying magnetic field gradient with a magnitude of at least 1 milliTesla per meter and a rise-time of less than 10 microseconds. The coil may be comprised of overlapping, non-overlapping or partially overlapping coil segments that may individually energized to further improve the operating characteristics of the coil to further decrease bio-effects in magnetic resonance imaging through the use of reduced pulse lengths and multi-phasic magnetic gradient pulses.

    摘要: A fluorometer includes a light source to generate excitatory light toward a tissue, the tissue generating fluorescent light in response to the excitatory light. The fluorometer also includes a light sensor to receive the fluorescent light and generate a digital signal. A processor is connected to the light sensor to receive the digital signal and generate a digital image, and a display displays the digital image. The tissue generates fluorescent light as a result of excitation of at least one intrinsic tissue metabolic product. A method for distinguishing between viable and non-viable tissue using the fluorometer also is described.
