Extra-oral dental x-ray imaging methods and systems are disclosed. An x-ray source exposes x-rays to an object to be imaged and an x-ray imaging device produces multiple frames during at least part of the exposure. The x-ray imaging device has an active area with a long dimension m and a short dimension n with m/n at least 1.5. A manipulator moves along a path the imaging device between consecutive radiated frames during exposure. The manipulator enables movement of the x-ray source and the imaging device by means of selective translation and rotation about at least one rotational axis located between a focal point of the x-ray source and the x-ray imaging device. An exposure profile program produces a substantially linear projection of at least part of said object to be imaged, said exposure profile program comprising at least one substantially linear section.
