An intra-subject position display system for displaying a position of an intra-subject device, which is introduced into a subject and moves therein, wherein a relative position of the intra-subject device to an outer surface of the subject is detected and displayed. Also disclosed is a toner comprising toner particles containing at least a binder resin and a coloring agent comprising the above surface-modified coloring particles. Methods include enhancing connections between education institutions and prospective applicants by setting up mutually agree appointments. Also, the write signal of the light modulating element is modulated in conformity with the control of the amount of projection light, whereby it becomes possible to expand the display dynamic range while compensating for the display luminance level. A second passageway is formed in the second connector portion and extends along a second longitudinal axis. During the processing step, an ellipsoid inscribed in the region of interest is modeled for deciding whether the image elements inscribed in this ellipsoid correspond to a nodule, and, for each zone of the region of interest extending beyond the ellipsoid, the image elements are identified which do not belong to the module according to mathematical morphologic criteria.
