Abstract
An imaging system intended for imaging fast-moving objects, comprising an X-ray source, a scintillating screen, a shutter and a detector of the beam emitted by the shutter, and a processing unit connected to the detector, where the shutter is positioned between the scintillator screen and the detector, and a support for the object to be observed is positioned downstream from the X-ray source and upstream from the scintillator screen, where the shutter is a shutter which can be controlled at high frequencies, for example higher than approximately 1 kHz, where the shutter is fixed and the transmission of the signal originating from the scintillator screen towards the detector is controlled by electrical polarization means controlled by a control unit.
Claims23
A system for imaging an object, the object being configured to perform a movement in response to an incoming signal, and where the system comprises:
- an X-ray source;
- a scintillator screen;
- a fixed shutter configured to be controlled at high frequencies;
- a detector of the beam emitted by the shutter, the shutter being positioned between the scintillator screen and the detector;
- a processor connected to the detector;
- a support for the object to be observed positioned downstream from the X-ray source and upstream from the scintillator screen;
- and
- a controller configured to control a voltage generator to polarize the shutter to allow transmission of the signal originating from the scintillator screen towards the detector, the controller being further configured to control transmission of a wireless signal to cause the object to perform the movement, wherein the controller is configured to control the voltage generator to polarize the shutter according to a timing of the transmission of the wireless signal.
