发明名称 MAMMOGRAPHIC APPARATUSES
摘要 Methods and apparatuses in mammographic photography, wherein the breast (M) to be photographed is pressed and spread between holders (6,7) attached to the photographing apparatus. A beam (R) of X-radiation is directed from one side of the holders (6,7) through the breast (M) placed between the holders at depicting means (21) placed at the opposite side of the holders in relation to the source (2) of X-radiation, said depicting means being placed inside a film cassette or equivalent placed in connection with the frame of the apparatus. The breast (M1) to be photographed is placed on the top face of the lower holder (7), against which the breast (M1) to be photographed is pressed from the root portion (J) of its upper side by means of the outer tip portion (6') of the upper press member (6); the upper press member (6) is displaced by pivoting it around its articulation point (8) so that it becomes substantially parallel to the support plane of the lower holder (7) in the frame part (10) that is stationary relative the source (2) of radiation and the part (3) for holding the depicting means (21); and when the upper and lower holders (6a,7a) become substantially parallel to one another, if necessary, the pressing of the breast is continued further by displacing the upper press member (6a) in its linear guides so that it retains its orientation.
