    Abstract: A method for magnetic resonance imaging is described in which imaging sequences, consisting of RF- and gradient magnetic field pulses (RF, Gx, Gy, Gz) are optimised with respect to a relevant parameter (SAR, signal-to-noise, etc.) prior to applying the RF- and gradient pulse sequence to the object or patient (7) to be imaged. This reduces the amount of different sequences to a limited number of basic sequences from which an operator has to choose and allows adaptation of the sequence to the particular image to be obtained.

    Abstract: A method of imaging a spatial distribution of a noble gas by nuclear magnetic resonance spectrometry includes detecting a spatial distribution of at least one noble gas by NMR spectrometry and generating a representation of said spatial distribution of the noble gas. The noble gas is selected from noble gas isotopes having nuclear spin, preferably Xenon-129 and/or Helium-3. The noble gas is at least thermally or equilibrium polarized and is preferably hyperpolarized, most preferably hyperpolarized by optical (laser) pumping in the presence of an alkali metal or by metastability exchange. The generation of the representation of the noble gas spatial distribution includes at least one dimension, preferably 2 or 3 dimensions of the spatial distribution. The noble gas may be imaged according to the invention in chemical or biological systems, preferably in a human or animal subject or organ system or tissue thereof. Also, apparatus for nuclear magnetic resonance imaging of the spatial distribution of at least one noble gas includes means for imaging a noble gas by NMR spectrometry and means for providing and/or storing imageable quantities of a noble gas, preferably hyperpolarized Xenon-129 and/or Helium-3. Also, a medical composition includes a medically acceptable bifunctional gas effective for in vivo anesthesiological and NMR imaging functions, including at least one noble gas, preferably hyperpolarized Xenon-129 and/or Helium-3.

    Abstract: Methods of preparing solid apatite particles using a microfluidizer, for use in medical diagnostic imaging such as magnetic resonance imaging, X-ray, and ultrasound. The desired apatite particles are synthesized, passed through a microfluidizer, and purified to remove excess base, salts, and other materials used to synthesize the particles. The microfluidizer causes two high pressure streams to interact at ultra high velocities in a precisely defined microchannel. Microfluidization of preparations causes small (

    Abstract: An NMR system acquires data during the application of a readout gradient that varies in amplitude. The NMR signal is sampled uniformly in time and is mapped to NMR data which is sampled uniformly in k-space by a digital filter. Sets of stored filter coefficients adapt the digital filter to different readout gradient waveforms and different fields of view and image resolution.
