    摘要： A method for automatically selecting a number of Gaussian modes for segmentation of a cardiac magnetic resonance (MR) image, including: identifying a left ventricle (LV) in a cardiac MR image slice; quantifying the LV blood pool; obtaining a mask for the LV blood pool; generating a ring mask for a myocardium of the LV from the LV blood pool mask; fitting three Gaussian modes to a histogram of the image slice to obtain a corresponding homogeneity image for the myocardium; computing a quality of fitting (QOF) measure for the three Gaussian modes based on the corresponding homogeneity image; repeating the fitting and computing steps for four and five Gaussian modes; and selecting the homogeneity image of the number of Gaussian modes with the largest QOF measure as the homogeneity image for processing.

    摘要： A machine tool is provided with a bit-changing apparatus including a cam, a rocker, a roller, a linkage, a pulling element, a disc and clips. The cam is attached to the machine tool. The roller is attached to the rocker and movable against the cam. The linkage includes at least one track attached to the machine tool, a sliding element attached to another end of the rocker and movable on the track, and a connecting rod formed with an end pivotally connected to the machine tool and another end pivotally connected to the rocker. The pulling element is provided between the rocker and the machine tool so that the roller is kept against the cam. The disc is rotationally supported on the rocker. Each of the clips is attached to the disc and used to clip a holder for holding a bit so that a selected bit can be engaged with a bit-driving unit of the machine tool.
