20110121969 | REMOTE MAINTENANCE OF MEDICAL IMAGING DEVICES - A medical imaging device that uses electromagnetic or acoustic information to generate a patient image is remotely maintained. A set of operational characteristics for the device is maintained by a maintenance system disposed remotely from the device. Data from sensors disposed local to the device are received over a network at the maintenance system. A set of parameter measures is derived from the received data and analyzed in comparison with the set of operational characteristics to identify a predicted malfunction of a component of the device. The maintenance system is thus able to initiate a repair of the medical imaging device by generating an alert in response to identification of the predicted malfunction. | 05-26-2011 |

20140020469 | TESTING OF ACOUSTIC IMAGING SYSTEMS OR PROBES - Appliances and methods are disclosed for testing operation of an acoustic device that generates beams of acoustic energy. An imaging array generates electrical signals in response to impinging receipt of acoustic energy. An acoustic-energy direction system is disposed to focus acoustic energy onto the imaging array. A controller is electrically coupled with the acoustic device and with the imaging array. The controller has instructions to generate an image on a display from electrical signals received by the controller from the imaging array. The electrical signals are received by the controller in response to generation of a beam of acoustic energy by the acoustic device. The beam of acoustic energy is directed towards the acoustic-energy direction system. The image provides a representation of the generated beam of acoustic energy. | 01-23-2014 |
