摘要： A system and method for performing a medical imaging process includes arranging a subject to be imaged in a magnetic resonance imaging (MRI) system and performing, using the MRI system, a magnetic resonance (MR) imaging pulse sequence. While performing the MR pulse sequence, electron paramagnetic resonance (EPR) pulses are performed at least during the application of the phase encoding gradients or only during the MR pulse sequence. Data is acquired that corresponds to signals from the subject excited by the MR pulse sequence and the EPR pulses. At least one image of the subject is reconstructed from the data.

摘要： Embodiments of the present invention address the problems with previously known MRI enhancement resonators. The embodiments provide capacitances that are sufficiently large to result in resonance frequencies that are sufficiently low for medical MRI applications in devices that are sufficiently small for implantation into the body. Further, the capacitance and resonance frequency of the MRI enhancement resonator may be easily adjusted to particular desired values by selecting corresponding thin-film dielectrics, or thicknesses of such thin-film dielectrics. Moreover, the design and geometry of the embodiments provide MRI enhancement resonators with high Q-factors. The construction and material of such MRI enhancement resonators also yield flexible and biocompatible devices that are appropriate for applications involving implantation into the body.

摘要： An inductively coupled magnetic resonance local prostate radio frequency coil (10) includes at least two connected electrically conductive loops (50) and an interface device (80). The at least two connected electrically conductive loops (50) are tuned to receive magnetic resonance radio frequency signal components along an axis of a subject disposed in a main magnetic field (B0) orthogonal to the axis of the subject (i.e. an open MRI system having a vertical magnetic field) and generate one or more currents indicative of the received magnetic resonance signal components. The interface device (80) connected to the at least two conductive loops transmits measures of the one or more currents to a signal processing system.

摘要： The present application discloses a guidewire for magnetic resonance imaging with a single channel design to reduce complexity and to provide conspicuous tip visibility under MRI. In one embodiment, a guidewire body includes an antenna formed from a rod and a helical coil coupled together. The helical coil can have multiple windings without any gaps between the windings. The rod passes through the windings of the helical coil and is coupled to the helical coil using a conductive joint positioned at an end of the rod and at an end of the helical coil. Insulation can be positioned between the rod and the windings of the helical coil. The configuration allows visibility of the antenna along the length of a rod, except where it enters the windings of the coil. Thus, the tip visibility is enhanced as being separated from the rod.

摘要： A high-pass two-dimensional ladder network has been described for high-field MRI and credential applications. The next-to-highest eigenvalue of the network corresponds to a normal mode giving rise to B1 fields with good spatial homogeneity above the resonator plane. Other eigenvalues may also be used for specific imaging applications. In its most basic form, the ladder network is a collection of inductively coupled resonators where each element of the array is represented by at least one conducting strip having a self-inductance L, joined by a capacitor C at one or more points along each resonator. In the strong coupling limit of the inductively coupled high-pass two-dimensional ladder network resonator array, the array produces a high-frequency resonant mode that can be used to generate the traditional quadrature B1 field used in magnetic resonance imaging, and in the limit of weak or zero coupling reduces to a phased array suitable for parallel imaging applications.
