| 20080200800 | RESPIRATION SUPPRESSING MAT AND MAGNETIC RESONANCE IMAGING APPARATUS AND METHOD - A respiration suppressing member includes a main body of an elastic material which is formed into a shape having a pressurizing portion for pressurizing that portion of the abdomen of a subject under imaging diagnosis by a medical modality which is located below the sternum and between the right and left ribs of the subject. | 08-21-2008 |
| 20080231271 | Magnetic resonance imaging apparatus and magnetic resonance imaging method - An MRI apparatus includes an imaging signal acquisition unit, a motion signal acquisition unit, a motion amount determination unit, a motion correction unit and an image reconstruction unit. The imaging signal acquisition unit acquires MR signals as imaging signals. The motion signal acquisition unit repetitively acquires MR signals having PE amount less than that of the imaging signals as motion signals. The motion amount determination unit obtains a motion amount using the motion signals. The motion correction unit performs correction processing of the imaging signals in accordance with the motion amount. The image reconstruction unit reconstructs an image using the imaging signals after the correction processing. | 09-25-2008 |
| 20080281186 | Magnetic resonance imaging apparatus and control method thereof - A magnetic resonance imaging apparatus includes a collection unit which applies a uniform static magnetic field to a subject and also applies a radio-frequency magnetic field and a gradient magnetic field to the subject in accordance with a predetermined pulse sequence to collect a magnetic resonance signal from the subject, a imaging unit which images the subject based on the magnetic resonance signal collected by the collection unit, a detection unit which detects a respiratory level of the subject, an informing unit which informs the subject of whether the detected respiratory level falls within an allowable range, and a unit which controls the collection unit and the imaging unit in such a manner that the magnetic resonance signal for imaging is collected and the subject is imaged based on the thus collected magnetic resonance signal for imaging when the detected respiratory level falls within the allowable range. | 11-13-2008 |
| 20100094121 | MAGNETIC RESONANCE IMAGING APPARATUS AND MAGNETIC RESONANCE IMAGING METHOD - A magnetic resonance imaging apparatus includes a collection unit which collects a magnetic resonance signal from the subject by applying a uniform static magnetic field to a subject and also applies a radio-frequency magnetic field and a gradient magnetic field to the subject in accordance with a predetermined pulse sequence, a reconstruction unit which reconstructs an image concerning the subject based on the magnetic resonance signal collected by the collection unit, a detection unit which detects a respiration level of the subject, a control unit which controls the reconstruction unit to reconstruct the image based on the magnetic resonance signal collected by the collection unit in a state wherein a peak of the detected respiration level falls within an allowable range, and a change unit which changes the allowable range based on a change in a plurality of peak values of a plurality detected respiration levels. | 04-15-2010 |
| 20110071382 | MAGNETIC RESONANCE IMAGING APPARATUS AND MAGNETIC RESONANCE IMAGING METHOD - According to one of the aspects of an MRI apparatus of the present invention, the MRI apparatus includes an imaging data acquiring unit and a blood flow information generating unit. The imaging data acquiring unit acquires imaging data from an imaging region including myocardium, without using a contrast medium, by applying a spatial selective excitation pulse to a region including at least a part of an ascending aorta for distinguishably displaying inflowing blood flowing into the imaging region. The blood flow information generating unit generates blood flow image data based on the imaging data. | 03-24-2011 |
