    摘要: A Doppler ultrasound system automatically and repeatedly scans an area of interest to construct at least one velocity profile through segments of arteries over an area of interest. Each scan includes taking measurements of blood flow in the area of interest substantially simultaneously from different angles. The velocity profiles and delta velocity profiles are automatically analyzed to determine a number of parameters indicative of potentially stenotic areas within the artery. The parameters and their changing value along the length of the artery indicative of stenosis are detected and compared with predefined threshold values to determine potentially stenotic areas. Scanning by the Doppler ultrasound system is triggered at a predefined point in an ECG cycle of the patient.

    摘要: Unauthorized use of a secured device can be prevented using customized hardware that only permits operation of the secured device while an enable signal is being generated, and prevents its operation at all other times. The enable signal is only generated when variations in incoming ultrasound waves indicate that a specific ultrasound activation signal has arrived. This ultrasound activation signal is generated by an activation unit that is acoustically coupled into an ultrasound conductive body (e.g., a person's body). Because the ultrasound activation signal cannot cross air gaps, the ultrasound activation signal will only be able to reach its destination when both the activation unit and the secured device maintain acoustic contact with the ultrasound conductive body. In addition, the signal that is actually received by the secured device must be the same specific ultrasound activation signal that the secured device is expecting to receive.

    摘要: The operation of a heart of a patient is monitored by transmitting ultrasound energy into the lungs of the patient, receiving ultrasound energy reflected from the lungs of the patient, detecting Doppler shifts in the received reflections, and processing the Doppler shifts into power and velocity data. Cardiac cycles are identified based on the power and velocity data and a determination when an identified cardiac cycle is abnormal is made. When an abnormal cardiac cycle is encountered, data corresponding to the abnormal cardiac cycle is stored. The data that was stored is eventually output. Optionally, abnormal cardiac cycles are identified using match filtering.

    摘要: Blood or other fluids can be caused to interact with a gas by providing a plurality of fluid flow channels that are surrounded by nanotubes, each of the channels having an inflow end and an outflow end, wherein each of the channels is wide enough for the blood to flow through, and wherein the nanotubes are spaced close enough to each other to retain the fluid within the channels when the blood is flowing through the channels. The fluid is then passed through the through the channels while a gas is passed through the spaces between the nanotubes outside the fluid flow channels. This permits the gas to interact with the fluid in the channels.

    摘要: Methods and apparatuses are described for direct rapid measurement of pulmonary flow resistance. A measurement of a first pressure in a gas-tight chamber is received from a pressure sensor when a gas output port of the chamber is closed, a patient is blowing into a gas inlet of the chamber at a given pressure, and a gas-flow path between the inlet and output port has a resistance value. A measurement of a second pressure in the chamber is received from the pressure sensor and a measurement of gas flow through the chamber is received from a gas flow sensor when the output port is opened and the patient is blowing into the inlet to maintain the given pressure relatively constant. A pulmonary flow resistance is computed based upon the measurement of the first pressure, the measurement of the second pressure, the resistance value, and the measurement of gas flow.

    摘要: AC electric fields at particular frequencies and field strengths have been shown to be effective for destroying rapidly proliferating cells such as cancer cells. The effectiveness of such fields is improved when the field is sequentially switched between two or more different directions. The effectiveness of such fields can be improved even further by choosing the rate at which the field is switched between the various directions.

    摘要: An electrode for applying electric fields to a patient includes a plurality of ceramic elements (e.g., ceramic discs) that are designed to be positioned against the patient's skin. Electrical connections are made to the ceramic elements (e.g., using a flex circuit). Temperature sensors (e.g., thermistors) are preferably provided at at least some of the ceramic elements to sense the temperature at the skin beneath the ceramic elements, so that appropriate action can be taken if an overtemperature condition is detected.
