摘要： PURPOSE:To enable reconstruction of a tomographic image with a high picture quality with suppression of an artifact free from movement of an examinee toward a direction of reading signals by correcting signal collecting conditions, namely, a signal reading magnetic field or a magnetic resonance signal collected to match the movement of the examinee in the direction of reading signals. CONSTITUTION:Signal reading magnetic fields GR3-GR5 are applied to collect a magnetic resonance signal B' for monitoring with respect to movement of a specimen in a direction of reading signals at each signal collection sequence. Based on the magnetic resonance signal B' for monitoring, a reference spectrum in the direction of reading signals is calculated while a projection spectrum at each signal collection sequence is calculated to change signal collecting conditions in the direction of reading signals in response to a deviation between the reference spectrum and each projection spectrum so that a frequency spectrum of a magnetic resonance signal B used in image reconstruction is kept constant. Thus, an image which is reconstructed finally based on the magnetic resonance signal B has artifact suppressed as caused by the movement of the object to be inspected, thereby producing a tomographic image with a high picture quality.

摘要： PURPOSE:To image the information related to the position change quantity of the measured spin by applying the flow encode magnetic field several times, changing intensity, and applying the Fourier transformation related to the phase variation quantity for each image element of a sectional image. CONSTITUTION:The magnetic resonance signals for all the values are collected by successively changing the flow encode magnetic fields GR3 and GR4. A calculator 16 previously sets the max flow speed of the measured spin and the measurement resolving power of flow speed, and sets the application time, intensity, and the variation quantity of the inclined magnetic field wave form for providing the flow encode to the flow speed. Then the magnetic fields GR3 and GR4 are added in the direction for image-forming the flow speed onto the inclined magnetic field wave form, and the final inclined magnetic field data are transmitted to a sequence controller 15, and all the prescribed image data are collected on the basis of the data. Then each image element obtained for each intensity of the magnetic fields GR3 and GR4 is applied with Fourier transformation, and analyzed at the speed having one eighth of the max flow speed, and the image corresponding to each flow speed is prepared. Then, the density at each flow speed having the value of each image element is provided, and displayed on an image display device 18 so as to form the light and shade of brilliancy.

摘要： PURPOSE:To make it possible not only to treat a patient in a conventional way but also to diagnose and inspect his affected part while maintaining him at the same place without moving by providing a radiation detector that rotates synchronously with a radiator unit and detects radiation transmitted through the affected part. CONSTITUTION:For obtaining a projection image, X-ray 12 must be radiated along the cross-section of a patient (perpendicular to page surface). With a linear accelerator for medical use, X-ray is radiated for instance over an affected part to a total rectangle of about 40cmX40cm in area, then radiation of X-ray 12 given perpendicularly to page surface provides necessary information, and thus the X-ray 12 passing through a patient 1 can be detected with an X-ray detector 13. For measurement at a certain place of rotation, a single pulse-like radiation of X-ray permits collection of necessary projection data. For constructing a cross-sectional image, signals should be collected 180 times at least once every 1 degree angle during a period when the X-ray radiator 4 and X-ray detector 13 are rotated round for 180 degree angle. It is possible to obtain a cross-sectional image from X-ray transmission quantity thus collected, by means of the same algorithm and cross-sectional image unit as in X-ray CT.

摘要： PURPOSE:To reduce high frequency power by the generation of an effective rotary magnetic field, by arranging at least two frequency magnetic field generator sections as opposed to each other in different phase to feed a high frequency power equivalent to a phase shift between the positions thereof. CONSTITUTION:A high frequency signal is inputted from a high frequency input section 1 to be distributed with a distributor 5. A part of the high frequency thus distributed is fed to a high frequency magnetic field generating section 4 through a high frequency amplifier 2 and a matching device 3. The other thereof is inputted into a phase shifter 6 to delay the phase of the high frequency signal, for example, by 90 deg. and passed through a high frequency amplifier 2A and a matching device 3A to be fed to a high frequency magnetic field generating section 4A. Here, the distributor 5 and the phase shifter 6 are combined to differentiate the phase of the frequency current to be fed to the high frequency magnetic field generating sections 4 and 4A by a phase portion equivalent to a deviation in spatial layout of the high frequency magnetic field generating sections 4 and 4A. In distribution into N with the distributor 5, the high frequency current is supplied, shifting the phase thereof by 360 deg./N with the phase shifter 6. Thus, a high frequency power difference in the phase is fed to the respective high frequency magnetic field generating sections thereby enabling the generation of an efficient rotary magnetic field.
