Abstract: An image in which an area of interest on an image is optimally susceptibility-emphasized is obtained in susceptibility-emphasized imaging. A measuring order of plural echo signals is controlled in accordance with the size of a desired area of interest of an examinee. Preferably, a target frequency in a K space is determined in accordance with the size of the area of interest, and the measuring order of plural echo signals is controlled so that an echo signal corresponding to the target frequency is measured at a target echo signal or in the neighborhood of the target echo time.

Abstract: In multi-slice imaging of a magnetic resonance imaging apparatus based on a non-Cartesian sampling method in which an overlap portion is generated in k space, stable body movement correction is realized at high speed. In order to do so, the rotation and translation of an object is detected for each specific region (in the case of a hybrid radial method, each blade) using a most characteristic slice in the imaging region, and the detected body movement is used for body movement correction of the specific region in all slices. The slice used for correction may be determined using a mathematical analysis result, such as correlation. In addition, data collection and correction processing may be performed in parallel.

Abstract: In order to respond to positional changes of body motion, such as respiratory motion, in various directions and to prevent an increase in the imaging time due to acquisition of body motion information or the occurrence of dead time in the measurement, a control unit of an MRI apparatus acquires association information in which body motion information detected by an external monitor, such as a pressure sensor for monitoring the movement of an object to be examined, and body motion information measured from an NMR signal by the navigator sequence are associated with each other in advance. During imaging, body motion information from the navigator is estimated using body motion information detected by an external monitor mounted on the object to be examined and the association information acquired in advance, and control, such as performing gating imaging or correcting the imaging slice position based on the estimated body motion position, is performed.

Abstract: A discharge circuit for a decoupling capacitor to stabilize a voltage supplied from a first power supply unit to a first load includes a first capacitor, a first switch, and a discharge control circuit. The first capacitor is charged by power supplied from a second power supply unit that supplies power to a second load that is different from the first load. The first switch is arranged between the decoupling capacitor and ground. The discharge control circuit discharges, in a case where power supplied from the second power supply unit to the second load is cut off, charges of the decoupling capacitor to the ground by driving the first switch using charges stored in the first capacitor.

Abstract: In order to improve contrast and image quality in non-orthogonal measurement without sacrificing speed, in imaging which combines a fast imaging sequence for acquiring a plurality of echo signals in one shot with non-orthogonal system measurement, the shape of a blade in which an echo train of each shot is arranged includes a fan-shaped region having the radius and the arc of a circle centered on the origin of the k space, and a region overlapping an adjacent blade. During measurement, control is performed such that an echo signal for desired TE of each blade is arranged in a low spatial frequency region of a k space, and during image reconstruction, body motion between the blades is corrected using data of the overlapping regions.

Abstract: An image with a desired contrast is obtained while suppressing body motion artifacts caused by both random motion and periodic motion of an object. In order to do so, an imaging sequence using a non-Cartesian sampling method is executed so as to synchronize with a biological signal only at the start time and a repetition time (TR), which is an execution interval between shots within the imaging sequence, is maintained. In addition, a time difference between a delay time and a start time of each shot is calculated, and a shot with a predetermined time difference or more is executed again after the TR time.

Abstract: In the non-Cartesian measurement, image quality is improved while the advantages of non-Cartesian measurement are maintained. To realize the aforementioned, in the non-Cartesian measurement, artifacts caused by non-uniform data density in k-space are reduced. Therefore, each unit k-space is imaged by an inverse Fourier transform, the field of view of the image is enlarged in a direction in which data density is to be increased, and the image after the enlargement of the field of view is Fourier transformed and gridded as unit k-space that has a small k-space pitch in the direction in which the field of view has been enlarged and has an increased amount of data. This processing is repeated for all blades.

An angle A between two adjacent sides of the multiple sides for wafer processing chambers is greater than an angle B which is calculated by dividing 360° by the number of the total sides consisting of the multiple sides for wafer processing chambers and the two adjacent sides for wafer loading/unloading chambers.

Abstract: In order to obtain a high-quality image even in multi-slice imaging in a UTE sequence that uses a half RF pulse, a refocusing pulse of the slice gradient magnetic field is adjusted and applied so that the excitation profiles of positive polarity data and negative polarity data have phase distributions that are 180 [deg] inverted with respect to each other in side lobe portions. In addition, the irradiation frequency of the half RF pulse is adjusted so as to eliminate a position shift between the intensity distributions of the positive polarity data and the negative polarity data.

Abstract: The purpose of the present invention is to prevent a two-dimensional code to be additionally embedded from corrupting a two-dimensional code which has been embedded when a document in which the two-dimensional code has been embedded is copied or when a document in which the two-dimensional code has been embedded is overlaid on form data in which the two-dimensional code has been embedded. In the present invention, when it is detected that a second two-dimensional code is embedded in an input image, the input image is printed without overlay of a first two-dimensional code thereon. Furthermore, when form data for overlaying is stored, when it is detected that a third two-dimensional code is embedded in the form data or when it is detected that a second two-dimensional code is embedded in an input image, the input image is output without overlay of a first two-dimensional code thereon.
