  • Patent number: 5855554
    Abstract: A novel breast localization and biopsy system employs a chest support for holding the patient in a slightly rotated (20.degree.-30.degree.) prone position allowing the breast tissue hang downward and fit through an opening in the chest support, while holding the other breast against the subject away from the imaging region. A pair of support plates compress the breast tissue. At least one of the support plates has a grid with reference markers for localization and windows allowing a physician access to the breast tissue. A thick biopsy plate with a plurality of holes at marked positions fits into one of the grid openings and guides an interventional device, such a biopsy needle, into a desired location in a lesion. In an alternative embodiment, both breasts fit through the chest support. There are two stabilization plate assemblies, one for each breast and two medical imaging sources. Each source points from the lateral to medial support plate to accomplish imaging of both breasts simultaneously.

  • Patent number: 5807253
    Abstract: A patient isolation device is used as a safety device to provide electrical insulation between medical electronic equipment and portions of the equipment which come in contact with the patient. In one implementation of the patient isolation device, an RF coil is incorporated in a catheter connected to medical electronic equipment which tracks the position of the catheter. Typically, there is also medical imaging electronics to provide internal images of the subject along with an indication of the location of the catheter. Typically, the signal from the RF coil is provided to a preamplifier to amplify the signal. The isolation device is placed between the RF coil and the preamplifier such that MR response signals may pass through to the preamplifiers but in the event of a short or electrical malfunction the line voltage will not pass backward into the RF coil causing damage to the patient.

  • Patent number: 5705014
    Abstract: Instruments are constructed of a carbon fiber material optionally doped with a doping agent such as iron oxide, the instrument having a magnetic susceptibility being adjusted to a portion of a subject being imaged. Therefore there is little effect upon the lines of magnetic flux and the magnetic field homogeneity, reducing distortion in an MR image. These carbon fiber instruments exhibit virtually no magnetic torsional forces when inserted into a magnetic field. This is important, for example when the instrument is a scalpel. Doped carbon fiber has minimal affect on radiofrequency fields. The instruments do not affect the homogeneity of an applied homogeneous magnetic field or an applied radiofrequency field. Doped carbon fiber exhibits a rigidity large enough to allow construction of high strength instruments such as biopsy needles. It also has the ability to retain a sharp edge, allowing construction of scalpels and cutting instruments.
