  • Patent number: 8073100
    Abstract: A panoramic X-ray apparatus, comprising at least a support element (2), a patient support (9) arranged to be movable in a vertical direction and an imaging station (4a). The panoramic X-ray apparatus has a support structure (4) arranged to support at least the imaging station (4a), and it has an actuator (15) producing a vertical linear motion for moving at least the imaging station (4a) to different height positions. The panoramic X-ray apparatus comprises a transmission mechanism (28) which affects the velocity/travel distance of the vertical movement of the imaging station (4a) and which is connected at least to the actuator (15) and either to the aforesaid support structure (4) or to the aforesaid support element in such manner that the velocity/travel distance of the vertical movement of the imaging station (4a) is substantially greater than the velocity/travel distance of the motion imparted by the actuator (15) to the transmission mechanism (28).

  • Patent number: 6705758
    Abstract: A mobile X-ray apparatus has a carriage provided with at least one pair of independently driven driving wheels and a motor. The carriage includes a driving handle, which comprises sidebars, attached to a rotation axis solidly fixed to the carriage, and a crossbar, which is connected to the sidebars in an articulated manner to allow the turning movement of the sidebars about the said axis independently of each other. The apparatus also controls the operation of the motor by movements of the handle. The sidebars are provided with a toothed rim that moves along with the movement of the respective sidebar. The movements are measured by a potentiometer, which converts the movement into an electric signal by which the motor of the driving wheels is controlled.
