A system to acquire radiological images of an imaged subject is provided. A gantry moves a radiation source and image receptor to multiple positions in relation to an imaged subject. A controller comprises program instructions that include correlating sequence selectors with sequences of acquired images acquired at multiple positions of the gantry, detecting actuation of a first selector correlated to a first sequence, instructing the gantry to position the radiation source and receptor at a first position to acquire a first image in the first sequence, moving the radiation source and receptor while simultaneously detecting actuation of the validation pedal until reaching the first position, acquiring the first image, automatically instructing the gantry to move the radiation source and receptor to a second position to acquire a second image in the first sequence, repeating these steps to acquire the remainder of the images in the first sequence.
