X-ray dose compensation for radiographic apparatus with kV ripple

Patent ·
OSTI ID:5040209
This patent describes a radiographic apparatus. It comprises an x-ray tube for selectively generating a beam of radiation which is directed through a subject receiving area and impinges on a radiation detecting means; a control circuit for operating the x-ray tube with a selectable anode current and tube voltage; an operator input means for an operator to designate at least a selected anode current and a dose, the operator means being operatively connected with the control circuit for causing the control circuit to operate the x-ray tube at the selected current for a duration theoretically projected to irradiate the subject receiving area with the selected dose; a boost current determining means for determining a boost current from the designated current and dose; a current adjusting means for selectively adjusting the designated current in accordance with the determined boost current.
