Abrégé

An image analysis unit has a reliability calculation unit that calculates the reliability indicating the possibility that a lesion candidate is a lesion. A mark display control unit displays a mark reporting the lesion candidate on an ultrasonic image. In a continuous detection state where the reliability continues to meet the candidate detection conditions, the mark is continued to be displayed. During the time, the form of the mark is fixed from the time point when the candidate detection conditions are first met until a fixed form period elapses. The form of the mark is then changed as the reliability varies.

Abrégé

To provide a technique in which, in imaging using an EPI method, an occurrence of an artifact when phase correction is performed for each channel is avoided and the phase correction is accurately performed. A common phase correction value to be applied to data of all channels is calculated using pre-scan data of each channel. The common phase correction value is obtained by combining a difference phase obtained for each of the channels. The difference phase is obtained by complex integration, while an absolute value of each channel is maintained as it is. The combination is performed by complex average, and averaging processing according to a weight of the absolute value is performed. The occurrence of an artifact can be prevented by using the common phase correction value, and robust phase correction can be performed by including the weight of the absolute value.

Abrégé

Generation of artifacts caused by the FID signal is suppressed even when the parallel imaging is applied to the imaging using a spin echo type pulse sequence. In performing a pulse sequence of a spin echo type using an excitation RF pulse for exciting nuclear spin and an inversion RF pulse for inverting excited nuclear spin as a high-frequency magnetic field pulse, a high-frequency transmitter of a MRI apparatus changes the phase of the inversion RF pulse according to the phase encoding and the phase encoding number imparted for each echo signal. Specifically, the phase of the inversion RF pulse is controlled to be a quadratic function of the phase encode of the echo signal.

Abrégé

A magnetic resonance imaging apparatus captures a morphology image and a function image that are captured with respect to an equal imaging region of an object under examination. Processing for deforming the morphology image is performed using a deformation parameter and moving positions of structural objects included in the morphology image to respective positions of structural objects of a previously determined standard morphology. Then, the function image is deformed using a value of the deformation parameter used in deforming the morphology image to cause a position of a region included in the function image to coincide with a position of a corresponding region of the standard morphology or by using the standard morphology in an opposite direction using the value of the deformation parameter to cause a position of a region of the structural object thereof to coincide with a position of a corresponding region included in the function image.

Abrégé

A pitch of transducers is extended, while preventing occurrence of grating lobes. A receive beamformer sets synthetic apertures on an array of transducers that have received echoes of transmission of one transmit beam, and performs processing on received signals of transducers within the receive apertures to form receive beams, followed by performing synthetic aperture processing on the receive beams obtained by the transmission of transmit beams. The positions of the transmit aperture and the receive aperture in the transducer array direction are shifted for every transmission of the transmit beam. A motion vector of the receive aperture along the array direction of the transducers is made different from a motion vector of the transmit aperture so that a distance between phase centers in the successive transmission events is smaller than the case where the transmit aperture and the receive aperture are shifted with a constant vector for each transmission.

Abrégé

Provided is a magnetic resonance imaging apparatus with no occurrence of artifacts, even after noise removal by applying Wavelet transform to a zero-fill reconstructed image. Nuclear magnetic resonance signals acquired by the magnetic resonance imaging apparatus are processed to perform reconstruction with a reconstruction matrix extended by zero-filling an acquisition matrix, and then a zero-fill reconstructed image is produced. This reconstructed image is subjected to an iterative operation combining the Wavelet transform and L1 norm minimization to remove noise. Before the noise removal, a pre-processing is performed to change the reconstruction matrix size so that an artifact does not occur in the image after noise removal, an artifact portion appears outside the reconstruction matrix after the noise removal, or cutting out is performed so that no artifact appears after the noise removal. The matrix size is restored to its original size in the post-processing after the noise removal.

Abrégé

In brain analysis, anatomical standardization is performed when analyzing a region of interest (ROI). There are individual differences in the shape and size of the brain and by converting the brain into a standard brain, these differences can be compared with each other and subjected to statistical analysis. When generating a standard brain analysis, a large number of pieces of image data are classified into a plurality of groups based on their anatomical features. An intermediate template that is an intermediate conversion image and a conversion map is calculated for each group, and the calculation of the intermediate template and the generation of the intermediate conversion image are repeated while gradually reducing the number of classifications, so that a final standard image is generated. Using the standard image and the intermediate template calculated during the generation of the standard image, spatial standardization of the measured image is performed.
