摘要： A Cryogenic Cooling System generally comprises a portable Dewar and a charging station for the Dewar. In the preferred embodiment, a HTSC device, such as a MRI coil, is contained in the Dewar which uses liquid nitrogen as a cryogenic coolant. The Dewar includes a reservoir for holding cryogenic fluid, an optional wicking material, a transfer tube between the reservoir and the HTSC device (or wick), and a vacuum space. Preferably a vent channel is adjacent the reservoir and provides an escape path for evaporating gas from the wick and/or HTSC device. The vent channel preferably provides a feed-back system: as more cryogenic coolant is transferred via the transfer tube, more cool gas is vented through the channel which cools the reservoir and thereby reduces the transfer. A charging system may also be provided as a source of cryogenic coolant. In the preferred embodiment, the charging system comprises a relatively large reservoir for liquid nitrogen.

摘要： An improved cold storage refrigeration system and method is presented. A first heat exchanger located in a cold storage unit is connected by means of a series of vertical pipes to a second heat exchanger located below the first heat exchanger within a refrigerated space, forming an integrated tube assembly. To charge the cold storage unit, the tube assembly is operated as the evaporator of a conventional refrigeration circuit. During non-powered cooling, a portion of refrigerant is sealed within the tube assembly. The refrigerant vaporizes in the second heat exchanger and condenses in the first heat exchanger, thereby transferring heat from the refrigerated space to the cold storage unit. Defrosting of the second heat exchanger is accomplished by removing refrigerant from the second heat exchanger and circulating air above 0 degrees centrigrade around it.

摘要： A method for representing the structural information in a biological or physical sample is disclosed. In this method, a time-frequency representation of the spatial distribution within a sample is transformed into a color representation of the data. Furthermore, due to the directional sensitivity of the method for gathering the data, information about the structural anisotropy of the sample can also be encoded from the data. The application of this method to one or more regions within the sample enables a map to be generated which clearly illustrates quantitative measures of the structures present.

摘要： The disclosed innovation is a method for acquiring spatial frequency spectra from specific locations in a 3D sample using modifications of the current MRI techniques for localized NMR spectroscopy. The innovation in its simplest abstraction is to add the use of a read out gradient to the current NMR spectroscopy pulse sequences and record the resultant echo. These techniques generate spectra from a selected region or generate an image of the results over a region of the sample. These methods can be applied to analyzing the structure of trabecular bone as well as for analyzing or diagnosing disease in cases where there is a difference in the spatial frequency power spectrum due to physiologic or disease processes. Various embodiments are disclosed.
