An electronic module comprises a ventilation device used for the efficient cooling of the components of this module while at the same time minimizing the accumulation of solid particles. To this end, a selector switch is placed between an electrical power supply unit of the module and a motor of the ventilation device. This selector switch cyclically modifies the sense of rotation of the fan in order to suck in an airflow to cool the components and expel the airflow in order to expel the solid particles located in the module and on the ventilation device.

Ventilation device ventilating an electronic module

An X-ray emission device and a method of assembly of the device having a casing with a window and an X-ray tube place in the casing. The tube comprises an anode assembly equipped with an anode, a cathode assembly equipped with a cathode and an envelope containing the anode and the cathode. The longitudinal positioning of the X-ray tube in the casing is produced on the anode side. The angular positioning of the X-ray tube in the casing on a longitudinal axis is produced on the anode side. A bayonet on the casing fastens a rotation axis support for the anode. The cathode is fixed in an angular position predetermined in relation to the bayonet by pins.

X-ray emission device and method of assembly

A filter plate having defects that may cause image artefacts is moved during an exposure. The movement distributes the defects of the plate in the image to a point where they can no longer be seen in the image. Preferably, the shifting of the plate is done in the plane of the plate, in a direction perpendicular to the axes of the rollers used for in the manufacture of the plate.

Filter for a radiation emitter and apparatus

An X-ray emission device and method for a radiology apparatus comprises a cathode and a rotating anode, the anode being provided with a roughly cylindrical surface. The device forms a beam of electrons that bombards a portion of the roughly cylindrical surface of the anode that constitutes the focal point of emission of the X-rays. The position of the focal point of the anode relative to a reference position is dynamically controlled.
