摘要： PROBLEM TO BE SOLVED: To provide a magnetic resonance measurement technique capable of high speed imaging by shortening measurement time, while suppressing artifacts caused by body movement of a measuring object. SOLUTION: An excitation pulse for exciting a plurality of slice planes and an excitation pulse for exciting slice planes perpendicular to its slice planes are impressed, and a plurality of substantially parallel linear crossing areas are simultaneously measured. Spatial information of the linear direction of the crossing area is acquired by modulation by a gradient magnetic field. A spatial information of the direction perpendicular to the linear direction is acquired by changing a position of a plane, and an image is reconstructed. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To efficiently improve the accuracy of the unknown obtained under a condition in which the value of measuring factors is limited in the measurement to find the unknown included in a function from a plurality of measured values obtained by a plurality of times of measurement with different measuring factors when a signal obtained from a subject for examination is expressed as a function with a measuring factor as a variable.
SOLUTION: The condition for limiting the measuring factors is received, and under the condition, a set of measuring factors to minimize the difference between the initial value of an unknown parameter included in the function and the value of parameter obtained from the calculation assuming that a certain error is included in the measured value are calculated. The measurement is executed using the obtained set of measuring factors, and the parameter is calculated from the obtained measurement data.

摘要： PROBLEM TO BE SOLVED: To provide a diagnostic imaging agent used in both MRI (magnetic resonance imaging) and ultrasonic diagnostic equipment, having high imaging ability in ultrasonic diagnostic images and transferable from blood vessels to tissues.
SOLUTION: The diagnostic imaging agent contains a liposoluble or amphiphilic paramagnetic material or a super paramagnetic material, a water insoluble material having ≤37°C boiling point and a water insoluble material having >37°C boiling point and is brought to be fine particles with a stabilizer. The agent gives imaging effects in MRI, has little danger in bumping and gives site-specific ultrasonic imaging effects using phase changes from liquid to gas. Owing to those effects, safe diagnosis/therapeutic techniques are provided.
