    摘要: Apparatus associated with improved magnetic resonance imaging (MRI) guided needle biopsy procedures (e.g., breast needle biopsy) are described. One example apparatus includes a support structure configured to support a patient in a face-down prone position where a breast of the patient is positioned in a first free hanging pre-imaging position. The example apparatus includes an immobilization structure configured to reposition the breast into an immobilized position suitable for MRI and for medical instrument access. The immobilization structure may include a biopsy plate, a pressure plate, and MRI coils. The MRI coils are configured to be repositioned from a first position associated with the free hanging pre-imaging position to a second position associated with the immobilized position to facilitate improving the signal to noise ratio associated with signal received from the breast through the MRI coils. The biopsy plate is removable without removing either of the MRI coils.

    摘要: A method for fabricating a magnetic transducer having an air-bearing surface (ABS). An underlayer having a first and second regions and a bevel connecting these regions is provided. The first region is thicker and closer to the ABS than the second region. An intermediate layer conformal with the underlayer is provided. A hard mask layer having a top surface perpendicular to the ABS is formed on the intermediate layer. Part of the hard mask and intermediate layers are removed to provide a trench. The trench has a bottom surface and sidewalls having a first angle between the bottom surface and the intermediate layer and a second angle corresponding to the hard mask layer. A pole is provided in the trench. The pole has a pole tip, a yoke distal, and a bottom bevel. At least the yoke includes sidewalls having sidewall angles corresponding to the first and second angles.

    摘要: An RFID tag for use with an MRI machine has an integrated circuit and structure for protecting it from damage when exposed to an intense MRI RF transmitter field. The structure for protecting the integrated circuit may include a controllable low impedance device coupled across the integrated circuit, a controllable high impedance device coupled in series with the integrated circuit, and/or frequency selective RF filter.

    摘要: A memory array having memory cells comprising a diode and an antifuse can be made smaller and programmed at lower voltage by using an antifuse material having a higher dielectric constant and a higher acceleration factor than those of silicon dioxide, and by using a diode having a lower band gap than that of silicon. Such memory arrays can be made to have long operating lifetimes by using the high acceleration factor and lower band gap materials. Antifuse materials having dielectric constants between 5 and 27, for example, hafnium silicon oxynitride or hafnium silicon oxide, are particularly effective. Diode materials with band gaps lower than that of silicon, such as germanium or a silicon-germanium alloy, are particularly effective.
