  • Intracavity probe and interface device for MRI imaging and spectroscopy
    Patent number: 5476095
    Abstract: An insertable pickup probe and interface network for magnetic resonance imaging and spectroscopy. The pickup probe in the preferred embodiment is for use in imaging the male prostate and comprises an elongated shaft supporting a patient interface balloon at its distal end which contains a RF receiving coil. The interface balloon comprises an inflatable inner balloon enclosed by a flexible outer balloon. The receiving coil is positioned between the inner and outer balloons and placed intimately adjacent the region of interest by inflating the inner balloon to expand outwardly against the outer balloon. In addition, a non-stretchable planar material is provided on the surface on the inner balloon adjacent the receiving coil for ensuring that the receiving coil is placed adjacent the region of interest. The inner balloon is inflated by an inflator cuff connected to the shaft and communicated to the inner balloon by a first lumen in the shaft.

  • Piezo-electric line of sight corrector for inertial platform stabilized sensor in a stellar navigational system
    Patent number: 4123136
    Abstract: A line-of-sight corrector using piezo-electric crystals as actuators is provided for the inertial platform stabilized tracking telescope of an astro navigational system. The tracking telescope in the embodiment of the invention to be described herein includes a folded-type optical system, and the corrector is used to impart movement to the secondary mirror in the folded optical system to compensate for residual angular movements of the telescope which would otherwise perturb the image focused on the vidicon or solid state sensor in the telescope.
