  • Patent number: 10245002
    Abstract: For dose calibration in functional imaging, an amount of bias in a dose calibrator measurement of activity is determined using a spectroscopic detector. The bias may then be used to correct dose values for the same isotope used to determine a factory-based sensitivity of the functional imaging system. When local functional imaging systems are calibrated, any difference in sensitivity from the factory measured sensitivity may be due to local dose calibrator bias, so the difference in sensitivity is used to determine a local correction.

  • Publication number: 20120199421
    Abstract: Method and System of lubricating at least one moving part with a medium. The medium includes a dissolved mixture of lubricant and compressed gas. The amount of lubricant and compressed gas may be controlled in forming the dissolved mixture in response to input conditions. A user and/or external factors may be used to determine the input conditions. In response to the input conditions the amount of lubricant and compressed gas is delivered to the moving part that is housed in a pressurized chamber. The properties of the dissolved mixture can be adjusted, whereby the properties may include, but are not limited to, the following: viscosity, temperature, and thermal conductivity. This adjustment to the gas may be accomplished, for example, by releasing gas from the pressurized chamber in an amount to adjust the properties. In a further approach, lubricant may be scavenged from the pressurized chamber by returning surplus lubricant to its original source or other designated location.
