Title:
磁気共鳴イメージング装置、画像処理装置及び画像処理方法
Document Type and Number:
Japanese Patent JP6647836
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging apparatus which can properly removes noises from the whole of pixels even when difference in S/N among a plurality of pixels included in an image: to provide an image processing apparatus: and to provide an image processing method.SOLUTION: A magnetic resonance imaging apparatus 100 includes an image generation part 25, a feature amount calculation part, a correction part and a de-noise processing part. The image generation part generates an image on the basis of magnetic resonance signals generated from a subject. The feature amount calculation part calculates a feature amount relating to a pixel signal value on each of the plurality of pixels included in the image. The correction part corrects the feature amount of each of the plurality of pixels on the basis of sensitivity characteristic of a reception coil receiving magnetic resonance signals. The de-noise processing part reduces noise in the image on the basis of the distribution of the feature amount corrected by the correction part.SELECTED DRAWING: Figure 1
