FEEDBACK IN REAL TIME TO PREVENT GEOMETRIC POSITIONS OF HIGH C-ARM DOSE Russian patent published in 2017 - IPC G06F19/00 

FIELD: physics.

SUBSTANCE: device includes an image generator capable of changing the dosage of X-rays depending on the difference in the X-ray attenuation levels when passing through the object of interest to be displayed. Moreover, the image generator is further configured to allow any of the plurality of the image forming geometric positions, when obtaining the image. Furthermore, the device comprises: a input unit (201) configured to receive a request to change the current image forming geometric position for the updated image forming geometric position for use in obtaining the image; a memory unit (205) configured to store the functional relation between the image forming geometric positions and the X-ray dosage. The functional relation is based on the expected levels of the X-ray attenuation in the object of interest; an output unit (210) adapted to use the stored functional relation for providing a human operator with the X-ray image intervention shaper of the change indicattion in the X-ray dosage required in the updated image forming geometric position relative to the X-ray dosage necessary in the reference position.

EFFECT: achieving the goal.
