摘要： A simultaneous emission-transmission tomography in an MRI hardware framework is described. A method of multimodality imaging includes reconstructing, by a simultaneous emission transmission (SET) circuitry, a concentration image based, at least in part, on a plurality of selected γ-rays; and reconstructing, by the SET circuitry, an attenuation image based, at least in part, on the plurality of selected γ-rays. The plurality of selected γ-rays is emitted by a polarized radio tracer included in a test object. The selected γ-rays are selected based, at least in part, on a radio frequency (RF) pulse and based, at least in part, on a gradient magnetic field.

The magnet is attracted to and held by the carrier, with the guide interposed therebetween, due to the magnetic attractive force between the magnet and the carrier.

摘要： Offsets (short and long term) are significantly reduced in a Lorentz force magnetometer circuit. A modulated bias current supplied to the magnetometer is chopped by periodically switching its polarity. Magnetometer output is demodulated, then de-chopping performed to restore signal polarity output. Chopping of the bias current signal polarity modulates magnetic field signal to a frequency in which electrostatic force remains constant toward eliminating offset and long-term drift from said micromechanical resonator.

摘要： A magnetic force microscope capable of measuring the absolute value of a magnetic field with high resolution without causing a change in magnetization state of the probe. The magnetic force microscope includes a cantilever, a probe, a displacement detector that detects a displacement of the probe, a specimen carrier, and various transfer units. The magnetic force microscope that measures an undulation distribution as well as a magnetic field distribution on the surface of a specimen placed on the specimen carrier is further provided with a magnetic-field impress-unit that impresses a magnetic field to the probe, and an output of the magnetic-field impress-unit is controlled such that a magnetic force impressed onto the probe 5 is turned zero to thereby measure a magnetic field distribution on the surface of the specimen.

摘要： Some implementations provide a magnetoelectric magnetometer that includes a piezoelectric layer having a first end portion, a second end portion, and a third portion. The third portion is located between the first end portion and the second end portion. The magnetoelectric magnetometer includes a magnetostrictive element coupled to the third portion of the piezoelectric layer. The magnetostrictive element and the piezoelectric layer are configured to amplify a magnetically induced stress in the magnetostrictive element to the piezoelectric layer, resulting in an electrical response from the piezoelectric layer. The first and second end portions of the piezoelectric layer are fixed, while the third portion is free to bend.

摘要： A prestored database indicating a correspondence of δ (depth)/ΔHcJ (coercivity increment) and a prestored database indicating information of Dy diffusion condition (diffusion coefficient, diffusion flux and processing time regarding Dy diffusion) are used to compute distribution of Dy introduction amount in a magnet from shape information of the magnet and information of a Dy introduction face and compute distribution of ΔHcJ in the magnet from the distribution of Dy introduction amount. Regarding a magnet having a coercivity that is distributed non-uniformly, a J/H curve is computed using the computed distribution of ΔHcJ, and a demagnetizing factor at a predetermined temperature is computed using a temperature coefficient.
