摘要： PURPOSE:To obtain the tomographic images of the eyeballs and optic nerves with less arch facts without compressing the eyeball by compasing of the eyeball fixer of balloons internally sealed with fluid and pressing and fixing means for pressing and fixing the balloons to the eyeballs. CONSTITUTION:The balloons 1a, 1b consist of elastic materials, such as natural rubber, and are fixed to the rear surface of a fixing band 2 by an adhesive agent, etc. The fixing band 2 is formed of a material having stretchability and magic tapes 3 are mounted to both ends of the band 2. Since the balloons 1a, 1b have elasticity, the balloons can regulate the movement of the eyeballs without compressing the eyeballs like gauze and towels. The tomographic images of the eyeballs and optical nerves with the less arch facts are obtainable in the case of the tomographing of the eyeballs and optical nerves by an MRI device.

摘要： PURPOSE:To efficiently execute the MR photographing of a neck part by providing plural variable capacity bodies, and a changing means which can change the capacity of each variable capacity body in accordance with the bending of the neck part. CONSTITUTION:The top plate fitting part 24 of a coil device 20 is attached to a top plate T. Subsequently, two variable capacity bodies 2 of the device concerned 1 are placed on a head/neck part placing surface 21a, and next, a connector part 22e is detached and a coil holding part 22 is opened in the direction C, and a head part H and a neck part N are placed on the variable capacity bodies 2a, 2b, respectively. In such a state, in the case of executing retroflexion photographing of the neck part N, an operator exhausts all the air included in the variable capacity body 2a for supporting the head part H by operating an exhaust port 6a and a valve 5. Subsequently, the operator operates a pump 6 and the valve 5 and sets the air capacity in the variable capacity body 2b for supporting the neck part N to, for instance, 250-300cc, raises the neck part N and bends backward the neck part N.

摘要： PURPOSE:To reduce the burden of a body to be examined and to decrease the fixed time of the body to be examined by installing an RF shield member having flexibility to a non-photographing part positioned in the vicinity of a photographing part of the body to be examined. CONSTITUTION:By allowing a body P to be examined, placed in a magnet device to generate a magnetic resonance phenomenon, a magnetic resonance image of this body P to be examined is obtained. In this case, an RF shield member 2 having flexibility is installed in a non-photographing part positioned in the vicinity of a photographing part (for instance, a hand) P of the body P to be examined. By this RF shield member 2, an RF signal to the non- photographing part is shielded, and generation of a magnetic resonance signal is prevented. Also, since this RF shield member 2 has flexibility, it can be installed easily in the non-photographing part positioned in the vicinity of the photographing part of the body P to be examined.

摘要： PROBLEM TO BE SOLVED: To set a section in a desired three-dimensional position quickly, accurately and easily by providing an altering means for arbitrarily altering at least either of the direction and the position of an area in a three-dimensional space. SOLUTION: A reference image is stuck to a reference section SEC2, whereby images of two sections, the reference section SEC2 and a current image-pickup section SEC1 are displayed in three dimensions on a sectional position display window 402. At this time, either of the images positioned on this side such as a reference image is previously processed to a transparent image. Thus, the picked up image of the section positioned in rear or the three-dimensional model image can be observed in the transparent state. Accordingly, while the spatial position relationship between a tested body and an area to be image- picked up is precisely recognized, the area to be image-picked up can be set in a desired three-dimensional position quickly, accurately and easily, and the image of the image-picked up area can be displayed in real time to be observed.

摘要： PROBLEM TO BE SOLVED: To make a pneumonic area into an image uninvasively without giving contrast media though it is difficult in a conventional manner by providing a moisture supply means for supplying atomized moisture, scanning the pneumonic area by means of a scanning means in a state where moisture is supplied to the area and magnetically collecting scan echo signals. SOLUTION: A breath holding method and an ECG gate method are commonly used in case of a first-time imaging scan and atomized moisture supply is started by an atomizer 20 by a proper timing after the end of the imaging scan. Then the second time imaging scan is executed in a way being the same as that of the first time one after a prescribed time elapses. That is, the pneumonic area is scanned in a state without moisture supply by the atomizer 20 to obtain a group of echo signals and also the area is scanned in a state where moisture is supplied by the atomizer 20 to obtain the group of echo signals. Each difference between the obtained two groups of echo signals at every pixel is obtained, MR image data concerning the differences are created and the MR image of the pneumonic area is displayed in display equipment 12.

摘要： PROBLEM TO BE SOLVED: To provide a blood flow image which enhances the visibility and discriminability of a blood vessel by securing the clearness of the blood vessel itself, and restraining MR signals from substantial parts such as fat and muscles. SOLUTION: This MRI device includes a means whereby a first pulse sequence PS-A for collecting echo signals by selectively exciting the spin of an imaged surface is executed for each amount of phase encoding, a means whereby a second pulse sequence PS-B including prepulses which pre-excite a surface different from the imaged surface and collecting echo signals by selectively exciting the spin of the imaged surface after application of the prepulses is executed for each amount of phase encoding before or after the first pulse sequence, and a means whereby two frame images are reconfigured from separately obtained echo signals to originate a differential image between the images. The first and second pulse sequences include rephase pulses and reading pulses that reverse the polarity of a gradient magnetic field in a reading direction based on FE method.

摘要： PROBLEM TO BE SOLVED: To provide an RF coil device for a shoulder for use in MRI, which can be naturally worn in both arm-lifted and arm-lowered states and which secures sufficient coil sensitivity.SOLUTION: In one embodiment, the RF coil device includes a base plate, a belt member, a first coil element, a second coil element in a base plate, and a connector section. The belt member, which has one end and the other end coupled to locations away from each other on the base plate so that its central part can be positioned on the front side of the base plate, is bent so that a cavity for inserting a subject's arm can be formed between the central portion and the front side of the base plate in a coupled state. The first coil element, which comprises a first partial coil in the belt member and a second partial coil in the base plate, is formed into a looped coil element by connecting both the first and second partial coils together. The connector section makes the base plate and the belt member detachably coupled together, and makes the first and second partial coils connected together in the coupled state.

摘要： PROBLEM TO BE SOLVED: To provide an image capable of reducing frequencies of misreading a signal change due to the pulsation and the movement of a patient, as a signal change due to an arrival of imaged fluid.
SOLUTION: An imaging scan for reconstructing a tomographic image is performed after a monitoring operation. The monitoring operation is to repeat the steps of: performing a monitoring scan for collecting data representing a concentration distribution of the contrast medium in a monitoring region (Sa4), reconstructing a reconstructed image representing the concentration distribution of the contrast medium in the monitoring region from the data acquired by the monitoring scan (Sa4), generating a monitoring image consisting of the maximum signal value calculated every pixel from a reconstructed image newly reconstructed and the reconstructed image previously reconstructed (Sa6), and monitoring the coming of a start timing of the imaging scan (Sa2 and 3), until the start time comes in.
