A radiography system includes: a radiation source that emits radiation; an imaging stand having a detection panel that generates a radiation image by detecting the radiation; a lifting device on which a subject to be examined is placed; a misalignment amount detection device that detects a relative misalignment amount between the imaging stand and the subject to be examined; and a lifting control device that lifts and lowers the lifting device on the basis of the misalignment amount detected by the misalignment amount detection device.

The present disclosure relates to an X-ray device, and an X-ray device according to an embodiment of the present disclosure comprises: a radiator configured to radiate an X-ray; a distance measurement sensor configured to measure a value of a distance to an object; and a controller configured to acquire a first separation distance between an X-ray radiation focal point of the radiator and a subject, and control operation of the radiator based on the acquired first separation distance.

An apparatus for Digital Imaging in the Head Region of a Patient includes an X-ray source and an X-ray sensor, supported on a rotary arm supported on a structure by a motor driven translation and rotation means. The rotary arm is provided with adjustment means for varying the distance between the source and the sensor. A control unit, that controls the source, the sensor, the adjustment means, and the translation and rotation means Collision detection means provided in the source and sensor detect a possible collision of the source and/or sensor with the patient during the motion of the source and/or sensor and the control unit responds to such detected possible collision.

Imaging systems and methods may facilitate positioning an imaging device in a procedure room. A 3D image of a subject may be obtained, where the subject is to have a procedure performed thereon. A view of the 3D image of the subject may be adjusted to a desired view and an associated 2D image reconstruction at the desired view may be obtained. A position for the imaging device that is associated with the desired view of the 3D image of the subject may be identified. Adjusting a view of the 3D image to a desired view and obtaining a 2D image reconstruction may be performed pre-procedure, such that a user may be able to create a list of desired views pre. A user may adjust a physical position of the imaging device to obtain reconstructed 2D preview images at the adjusted physical position of the imaging device prior to capturing an image.
