  • Patent number: 12290323
    Abstract: A single-sided magnet and magnetic resonance imaging (“MRI”) system are portable and lightweight, enabling use as a point-of care (“POC”) MRI device. The portable MRI system includes a magnet assembly containing layers of magnet blocks, such as rare-earth magnet blocks. The magnet blocks are arranged in concentric rings in each layer, and surround a central aperture extending through the magnet assembly. The central aperture is sized to allow a medical instrument, such as a needle, to pass through the central aperture. The portable MRI system can therefore be used for image guidance in lumbar puncture (“LP”) and other medical procedures.

  • Patent number: 12287388
    Abstract: A static magnetic field generator generates a non-magnetic field region. An AC magnetic field application instrument applies an AC magnetic field to the non-magnetic field region. A detection coil has an axis parallel to a direction of the AC magnetic field in order to detect a magnetization signal. A measuring instrument is connected to the detection coil. A resonance frequency variable device includes a capacitor connected in parallel to the detection coil in order to adjust a resonance frequency of the detection coil and the measuring instrument. A capacity of the capacitor is adjusted such that a resonance frequency of a closed circuit including the detection coil, the measuring instrument, and the resonance frequency variable device including the capacitor coincides with a frequency of a harmonic signal.

  • Patent number: 12274532
    Abstract: A method and apparatus of automatically locating in an image of a blood vessel the lumen boundary at a position in the vessel and from that measuring the diameter of the vessel. From the diameter of the vessel and estimated blood flow rate, a number of clinically significant physiological parameters are then determined and various user displays of interest generated. One use of these images and parameters is to aid the clinician in the placement of a stent. The system, in one embodiment, uses these measurements to allow the clinician to simulate the placement of a stent and to determine the effect of the placement. In addition, from these patient parameters various patient treatments are then performed.

  • Patent number: 12263032
    Abstract: An apparatus and method for estimating one or more hemodynamic parameters such as cardiac output or stroke volume. Embodiments are based on the concept of incorporating information about vascular tone into hemodynamic parameter estimation to improve accuracy. More particularly, embodiments use a measurement of a time duration for a blood pulse to travel from the heart along a certain length of an arterial path as a proxy measure for vascular tone, and incorporate this into hemodynamic parameter estimation. Embodiments are also based on incorporating vascular tone proxy measurements for multiple different arterial paths to take account of vascular tone variations between different portions of the circulatory system.

  • Patent number: 12256952
    Abstract: The present invention relates to a system for the controlled fragmentation of solids by means of acoustic beams, comprising at least one acoustic beam generation unit (100); and one feedback and control unit (200) of said generation unit (100). Advantageously, the acoustic beams generated by the system are acoustic vortex beams; and the feedback and control unit (200) further comprises a feedback subsystem (12), configured to receive the information relating to the fragmented solids and to utilize it so as to adapt the operation of the acoustic beam generation unit (100). Given that the generation of shearing stresses is more efficient using vortex beams, the amplitudes of the ultrasonic field needed to fragment the calculi are much lower than in current extracorporeal shock wave lithotripsy techniques. Likewise, the system minimizes unwanted effects on soft tissues surrounding the solid.

  • Patent number: 12220273
    Abstract: Perfusion angiography combined with photoplethysmography imaging for peripheral vascular disease assessment A device (13) and method for performing perfusion imaging receive image sequences that are acquired simultaneously by an X-ray imaging apparatus (2) and by a photoplethysmography imaging apparatus (3). When temporally aligned, changes in the perfusion states of a perfused organic tissue over time are extracted from the two image sequences and an image is generated for display on a display unit (5) which indicates the changes in the perfusion states at various locations of the perfused organ tissue, thereby capturing both deep organ tissue and superficial organ tissue perfusion properties. A diminution in an image signal strength in the photoplethysmography images caused by a passage of a bolus comprising a previously administered contrast agent (10) can be used to align the two concurrently acquired image sequences in time.
