Patent
Rotary brush device and vacuum cleaner using the same
Hiroshi Nishimura,Seizo Hayashi +1 more
TL;DR: In this article, a rotary brush is incorporated in a cylindrical body, which is used to drive a motor and cooling air runs through the brush to protect the motor from overheating.
Patent
CT system for spirally scanning subject on a movable bed synchronized to X-ray tube revolution
Hiroshi Nishimura,Osamu Miyazaki +1 more
TL;DR: In this article, a computerized tomography system is described, which includes an X-ray generator for producing X-rays, an Xray detector array for detecting the X- rays transmitted through a subject, and a subject bed.
Patent
Quiet magnetic resonance imaging apparatus
TL;DR: In this article, a gradient magnetic field coil and a retaining member are fixed to the retaining member without damping, and a force for inhibiting deformation and vibration is applied by controlling a voltage applied to the piezoelectric device.
Patent
Method and apparatus for correction of phase distortion in MR imaging system
TL;DR: In this article, the phase distortion included in data acquired through imaging is corrected by representing it as a summation of the plurality of phase distortion patterns with weighting factors, which is invariable and hence it is not necessary to perform the measurement for each impage processed.
Patent
Magnetic-resonance (nuclear-spin) tomography instrument and method with noise attenuation
TL;DR: In this paper, the authors described a gradient magnetic field production device with at least one gradient magnetic coil and a retention part, which is deformed by an electromagnetic force as is produced when a current is passed through the coil.
