    摘要： A supporting and driving mechanism including a rotatable body and a supporting unit for assuring stable support and rotation of the rotatable body for a long time. The mechanism includes an axis member at either end of the rotatable body, a driven gear at one end of the rotatable body, two rollers and a driving gear of the supporting unit. The two rollers are placed parallel to each other and the distance between the closed surfaces of the rollers is smaller than the diameter of the axis member of the rotatable body. The driving gear engages the driven gear and transmits a driving force to the driven gear of the rotatable body. The driving force applied from the driving gear to the driven gear directs between the centers of the two rollers when the driving force is translated so that the origin of the force is brought to the center of the axis member of the rotatable body. Thus the axis member is pressed toward the two rollers while the rotatable body is driven by the supporting unit, whereby the position of the axis member is fixed and the stable rotation of the rotatable body is assured for a long time.

    摘要： The present invention scanes a plurality of MRI images while varying conditions for a sample usable in color-determination and MRI imaging, subjects the image data to a first independent component analysis to decompose the data into L independent component images, selects N points on the sample to create a training sample that is a set of L (typically three) independent-component image luminances and color components. This generates as many transfer functions as the color components which output one color component for an arbitrary combination of the L independent-component image luminances. For a colored MRI generating object a plurality of MRI images are scanned while varying conditions, and a second independent component analysis on the MRI images accomplishes generating L independent component images. A calibration process scaling luminance is executed and the transfer functions are applied to the calibrated independent component images to obtain a multichannel MRI color image.
