    摘要: A magnetic resonance measuring equipment capable of detecting a nuclear magnetic resonance signal with a higher sensitivity and a higher resolution in comparison with related magnetic resonance measuring equipment. The magnetic resonance measuring equipment modulates a nuclear magnetic resonance signal by applying a vibration (sonic wave) of a known frequency, which is higher than the frequency of the nuclear magnetic resonance signal, to an examination object, and detects the modulated signal by performing lock-in detection, which makes it possible that the magnetic resonance measuring equipment detects the nuclear magnetic resonance signal with a high sensitivity. In addition, after irradiating a local area of the object with an ultrasonic wave, and modulating the nuclear magnetic resonance signal derived from the irradiated local area, the magnetic resonance measuring equipment can detect the nuclear magnetic resonance signal with a high resolution.

    摘要: A failure is detected immediately and certainly, and continuation of processing in an unstable state is prevented. A first error detection code is generated from first information which is output as a result of execution of a predetermined program conducted by a first processor. A second error detection code is generated from second information which is output as a result of execution of the program conducted by a second processor which is configured so as to output the same computation result as that of the first processor. It is detected whether the first information is the same as the second information, and it is detected whether the first error detection code is the same as the second error detection code. Writing the first information or the second information into a main memory is controlled on the basis of a result of the detection.

    摘要: There is provided a biomagnetic field measurement apparatus capable of carrying out exact positioning work and highly sensitive signal detection. To bring a sensor surface close to a body surface while the sensor surface and the body surface are kept parallel, a cryostat is constructed so as to be capable of oscillating and expanding and contracting. A gantry is formed by three supports. A first support is a portal support that supports the whole of the gantry. A second support is supported on the first support, and is rotatable with a first direction being the axis. A third support is supported on the second support, and is movable in the axial direction of the cryostat as viewed from the second support. The cryostat is supported on the third support, and moves integrally with the third support.
