An image processing apparatus according to an embodiment includes a processing circuitry. The processing circuitry acquires pixel values of at least three different types of magnetic resonance (MR) images. The processing circuitry causes a display to display a diagram in which values based on the pixel values are arranged in a region with at least three-dimensional axes.

Image processing apparatus and non-transitory computer readable medium for visualizing magnetic resonance data

A magnetic resonance imaging apparatus includes sequence controlling circuitry configured: to obtain, during a time period after excitation of a first nuclide in a hyperpolarized state but no later than before obtainment of a first magnetic resonance signal from the first nuclide, a second magnetic resonance signal from a second nuclide that is different from the first nuclide and is in a non-hyperpolarized state, by exciting the second nuclide; and to control each of gradient magnetic field waveforms so as to cause both a first sum indicating a sum of application amounts of a gradient magnetic field related to the excitation of the second nuclide and a second sum indicating a sum of application amounts of a gradient magnetic field related to the obtainment of the second magnetic resonance signal to be close to zero, no later than before the obtainment of the first magnetic resonance signal.

According to one embodiment, a magnetic resonance imaging apparatus includes processing circuitry. The processing circuitry calculates power of a first RF magnetic field required for excitation at a first flip angle in a first target slice, acquires information on inhomogeneity of a transmission RF magnetic field for a cross section crossing the first target slice, and calculate power of a second RF magnetic field required for excitation at a second flip angle in a second target slice different from the first target slice for the cross section by using the information and the first RF magnetic field power.

Magnetic resonance imaging apparatus

A magnetic resonance imaging apparatus according to an embodiment includes a transmission coil and processing circuitry. The transmission coil is configured to apply a high frequency magnetic field to an object. The processing circuitry is configured to: derive, based on at least one of an imaging region and the body shape data of the object, a specific area in a field of view (FOV); and determine, based on a signal within the specific area, an output power level of a high frequency pulse signal supplied to the transmission coil.
