Abstract: A scintographic installation includes a patient-supporting table (10) and a stand (11) whose support column (19) is moveable along an axis OX. The invention lies in the fact that the table (10) is mounted on a rail (15) which is capable of taking up different angular positions about an axis parallel to the axis OZ. In a first position the rail (15) is parallel to OY and the stand (11) is in a position suitable for performing tomographic examination. In a second position, the rail (15) is parallel to the axis OX and the stand (11) is a position suitable for examining the entire body by displacement of the column (19), i.e. without displacing the bed (12).
