摘要： RF electric fields produced by electric potential differences in NMR probe coil windings may penetrate the NMR sample and sample tube causing sensitivity loss and noise in NMR spectroscopy. Counter-wound spiral coils placed on the opposite surfaces of a planar substrate or on two adjacent planar substrates produce electric potentials that minimize the electric field over the sample region, thereby increasing the sensitivity of the NMR probe. Alternatively counter-wound spiral coils placed adjacent to each other on the outer surface of two concentric cylindrical surfaces that surround the NMR sample minimize the electric field over the sample region. The electric potential of the spiral coils is reduced by adjusting a length of at least one coil.

摘要： A z-axis magnetic field gradient coil for nuclear magnetic resonance (NMR) spectrometry includes an etched double-sided flexible sheet having via connections running through the sheet. The vias interconnect two conductive patterns formed on opposite sides of the sheet. Each z-axis current lead is adjacent to another z-axis current lead oriented in the opposite direction, such that the z-axis current components of the two patterns cancel each other. The resulting net current component is in the x-y plane, and generates the desired z-axis magnetic field gradient.

摘要： An X-ray tube has an anode and a photocathode inside a vacuum envelope and an electron multiplier is disposed between them. Such an electron multiplier may be a plurality of sequentially disposed dynodes or a microchannel plate. Because of the secondary electron emission from such an electron multiplier, a higher-power radiation is obtained without requiring a high optical power level to generate photoelectrons. The vacuum envelope may be of a rotary type with the anode and photocathode having annular regions.

摘要： A method and apparatus for electrically heating an acupuncture needle that has been inserted into a subject is disclosed. An applicator unit contains an electrical heating element thermally coupled to an acupuncture needle and directly to the skin adjacent to the acupuncture needle. Regulation and control of the heat supplied by the applicator unit is achieved through the control of electrical power supplied to the heating element. Either temperature or power control can be selected, and temperature indication is provided. In use, after the acupuncture needle has been inserted through the subject's skin, the applicator unit is attached to the acupuncture needle and regulated electrical power is applied to produce controlled heat.

摘要： Low-temperature (cryogenic) radio-frequency (RF) coils for nuclear magnetic resonance (NMR) applications include composite multi-layered structures including an internal normal metal layer clad on both sides by external high-purity annealed aluminum layers. The magnetic susceptibilities of the internal and external layers are opposite in sign, and the thicknesses of the layers are chosen such that the composite structure has a net magnetic susceptibility equal to that of its surroundings (vacuum or support material). The internal layer can have a higher resistivity and magnetoresistance than the external layers. The use of high-purity, annealed aluminum for the external layers allows relatively high Q-factors for the cryogenic coils.

摘要： A real-time ultrasonic imaging system is disclosed which includes an array of transducers adapted for propagating ultrasonic energy into a body to be ultrasonically examined and for receiving reradiated energy from points within the body. A plurality of signal channels each includes a transmitter branch and a receiver branch associated with respective transmit and receive transducers, or both branches may share a single transducer. A transmitter branch activates a transducer to propagate the sonic energy and a receiver branch receives from the transducer electrical signals corresponding to the reradiated energy. Memory means in each receiver branch receive and store data indicative of the signal level passed to the channel by its associated transducer. Display means are provided for receiving the data from the memory means in each of the channels and for combining and processing such data to effect a real-time display of the bodily portion being examined. Timing generator means in each of channels, connected to the transmitter and memory means associated with that channel, activate the respective transducers at predetermined times to phase the transducers to enable steering and focusing of the array. The timing generator means also function to gate data into the memory and at a later time to gate out the data from the memory (at predetermined intervals), thereby controlling the bodily points from which the reradiated sonic energy is received and to enable steering and focusing of the transducer array during the receiving operation of such array. Control logic means are connected to the timing generator means for enabling the former to provide signals to the memory means and transmitters in each of the said channels.
