The horizontal wall members and the vertical member delimit the upper and lower sides and at least a vertical lateral band of a space for receiving at least one part of a patient body. The horizontal wall members also support means for generating a static magnetic field that permeates the patient receiving space. The apparatus further includes a patient table, supported in an intermediate position between the two horizontal wall members, and lies slightly above the lower horizontal wall part, the table being displaceable in at least one displacement direction, having at least one component of motion towards and/or away from the vertical connection member, and the table being rotatable about a vertical axis outside the magnet structure, i.e. outside the horizontal wall members.

摘要： A method for automatically detecting and tracking the contour of an image that uses a class of filters, obtained from the first order absolute central moment. The method provides the steps of filtering a starting image through the absolute central moment e(n,m) of the intensity of a pixel of the image, being n and m the coordinates of each pixel, where the absolute central moment is obtained with the following steps: determining for each n,m the local mean calculated in a neighborhood about a pixel of coordinates n,m of the starting image, thus obtaining a first filtered image; determining for each n,m the sum of the absolute differences between the intensity of a pixel of coordinates n,m of the first filtered image and the intensity of all the pixels contained in a neighborhood about a pixel of coordinates n,m of either the starting image or a second filtered image obtained from the starting image.
