Abstract: According to one embodiment, a magnetic resonance imaging apparatus includes an imaging condition setting unit and an imaging unit. The imaging condition setting unit is configured to set slice positions same as past slice positions to a same object and to set a table position of a bed with the object set to position a position representing a slice position designated out of the slice positions or a position representing a slice range designated out of the slice positions on a center of a magnetic field. The imaging unit is configured to acquire magnetic resonance data from the slice positions set for the object at the table position of the bed to generate image data corresponding to the slice positions based on the acquired magnetic resonance data.

Abstract: According to one embodiment, a nuclear medicine imaging apparatus includes a counting information collection unit, a determination unit, and a discarding unit. The counting information collection unit collects counting information including detection time of a gamma ray from a counting result output by a detector for counting light derived from a gamma ray, and stores the counting information in a buffer. The determination unit determines whether the volume of the counting information stored in the buffer exceeds a threshold. The discarding unit, in a case that the determination unit determines that the volume exceeds the threshold, intermittently discards, in chronological order, counting information whose detection time is within longer duration than predetermined duration used for generating two pieces of counting information obtained by counting pair annihilation gamma rays nearly coincidentally as coincidence counting information among the counting information collected from the detector.

Abstract: A magnetic resonance imaging apparatus according to an exemplary embodiment includes a first imaging unit, an identifying unit, and a second imaging execution unit. The first imaging execution unit acquires, after applying a labeling RF pulse to blood flowing into the myocardium of a subject, multiple non-contrast MR data for which the time intervals between labeling and acquiring data are different by performing sequential imaging of an imaging area including the myocardium in each segment of a k-space for a given time interval. The identifying unit identifies a time interval taken by the labeled blood to reach a given position in the imaging area. The second imaging execution unit sets the identified time interval and, after applying a labeling RF pulse to the blood flowing into the myocardium of the subject, acquires non-contrast MR data by imaging the imaging area including the myocardium.

Abstract: A magnetic resonance imaging apparatus according to embodiments includes an executing unit, an informing unit, a detecting unit, and a determining unit. The executing unit executes a pulse sequence to collect data of a subject at a constant cycle. The informing unit informs the subject of a timing of breathing in synchronization with the cycle at which the pulse sequence is executed. The detecting unit detects a breathing level or a respiratory cycle of the subject. The determining unit determines, when the pulse sequence is executed, whether to use the data collected by the pulse sequence for image reconstruction in accordance with the breathing level or the respiratory cycle of the subject.

Abstract: In the nuclear medicine imaging apparatus according to the one embodiment, the ADC converts the output data of each of the photodetectors to digital data. The counting information collecting unit collects counting results from the digital data, and the counting information storage unit stores the counting result in association with the digital data. The coincidence counting information generating unit generates coincidence counting information. The image reconstructing unit reconstructs a PET image, based on the coincidence counting information. The time correction data stores a correction time for each of the photodetectors. The system controlling unit controls to correct the detection time of the gamma rays in the digital data associated with each piece of the counting information by use of the correction time, and to generate new coincidence counting information. The system controlling unit controls to reconstruct a new nuclear medicine image, based on the new coincidence counting information generated.

Abstract: A feedforward control unit predicts the maximum value of the temperature of a gradient coil based on a power duty and a scan time of a pulse sequence, and a present temperature of the gradient coil. When the maximum value exceeds a predetermined upper limit, the feedforward control unit then instructs a temperature adjusting unit to start a water circulation in a chiller at the start of a prescan, and the temperature adjusting unit starts the water circulation based on the instruction.

Abstract: According to a Magnetic Resonance Imaging (MRI) apparatus, a scanning-parameter limit calculating unit creates examination information that represents scanning conditions for collection of magnetic resonance signal data based on scanning parameters set by an operator; a scanning-condition edit/scan positioning unit creates a time chart that indicates the type and a sequential execution order of an event to be executed when collecting magnetic resonance signal data based on the examination information created by the scanning-parameter limit calculating unit, and causes a time-chart display unit to display the created time chart.
