摘要： A radio-frequency coil has a first element and a second element both being adjacently arranged so as to nip a division/join portion. The first element has a first main loop portion provided along an arrangement plain surface and a first sub-loop portion provided along a surface substantially perpendicular to the arrangement plain surface. The second element has a second main loop portion provided along the arrangement plain surface and a second sub-loop portion provided facing the first sub-loop. The first sub-loop portion and the second sub-loop portion generate an induced electromotive force such that, among magnetic fields generated when a current flows in one coil, a summation of the magnetic fields, which interlink with the other coil, becomes zero.

摘要： A magnetic resonance imaging apparatus acquires magnetic resonance signals by the PI method using an RF coil unit having basic coils serving as surface coils which are arrayed with at least two coils along a static magnetic field direction (z direction) and at least two coils alone each of two orthogonal x, y directions. The coils are divided into an upper unit and a lower unit. The upper unit and lower unit are fixed by a band or the like to allow them to be mounted on an object to be examined. The signals detected by the respective surface coils are sent to a data processing system through independent receiver units and formed into a magnetic resonance image.

摘要： After a photoresist is applied onto a wafer, a contrast enhancement material (CEM) layer is applied onto this photoresist. A pattern is projected through this CEM layer onto the photoresist. Next, this CEM layer is removed from the photoresist and thereafter a new CEM layer is again applied onto the photoresist. Another pattern is projected through this new CEM layer onto the photoresist, whereby the photoresist is exposed in accordance with a composite pattern of the two patterns. This composite pattern can surpass the resolution limit of projection optical system.

摘要： An ultrasonic wave medical treatment apparatus capable of preventing the displacement of the focal point of the ultrasonic waves from the treatment target portion within the patient, eliminating a need for re-positioning of the ultrasonic wave applicator with respect to the patient, and taking MR images to be utilized during the treatment at a high resolution. In this apparatus, the ultrasonic wave applicator can be integrally incorporated within a treatment table for carrying the patient into the MRI gantry for taking the MR images. The surface coil for taking the MR images can be provided on a surface film of a water bag in the ultrasonic wave applicator, or on a body cavity probe on which the ultrasonic transducer is also provided. The mixing rate of the coupling fluid can be adjusted, and the impedance matching between the ultrasonic transducer and the driving circuit can be maintained by minimizing the reflected electric power from the ultrasonic transducer.
