Abstract There is disclosed a method for forming a radiogram of an object comprising the steps of energizing an X-ray source at a low level of radiation intensity wherein the X-ray source includes a slit diaphragm, pivoting the X-ray source during a first scanning of the object, moving an elongated X-ray detector in respect to the pivoting of the X-ray source to generate an output signal of intensity of the object during the first scanning thereof, measuring the output signal during at least a portion of said first scanning, energizing the X-ray source to a higher level of radiation intensity as determined by the output signal from the X-ray detector during the first scanning, pivoting the X-ray source during a second scanning of the object, moving the X-ray detector during the second scanning to generate a second output of radiation intensity and forming a radiogram from the second output signals.
A method for forming a radiogram of an object, which comprises the steps of: (a) energizing an X-ray source to a low level of radiation intensity, said X-ray source including a slit diaphragm; (b) pivoting said X-ray source during a first scanning of said object; (c) moving an elongated X-ray detector along a position corresponding to a position of said X-ray source during said first scanning thereby to generate output signals of radiation intensity; (d) measuring said output signals during at least a portion of said first scanning; (e) energizing said X-ray source to a higher level of radiation intensity as determined by step (d) to form a radiogram; (f) pivoting said X-ray source during a second scanning of said object at said higher level of radiation intensity; (g) moving said elongated X-ray detector along said position corresponding to said position of said X-ray source during said second scanning thereby to generate second output signals of radiation intensity; and (h) forming said radiogram from said second output signals.
