The slide mechanism includes at least one slide rail along the first direction and holds the X-ray detector so as to slide in the first direction. The rotary mechanism includes a rotation shaft and rotatably holds the slide mechanism. The arm holds the rotary mechanism and is operable.

The present disclosure relates to methods and systems for calibrating an X-ray apparatus. The X-ray apparatus may include an X-ray detector and a collimator. To calibrate the X-ray apparatus, the methods and systems may include moving the X-ray detector from a first position to a second position along a first axis of a coordinate system, wherein the first position is under a scanning table, and the second position is outside the scanning table; moving the collimator to align the collimator with the X-ray detector at the second position; determining one or more parameters; and determining a second value of the first encoder when the collimator is aligned with the X-ray detector at the first position based on the one or more parameters.

At least one example embodiment provides a method for automatic positioning of an X-ray source of a medical X-ray system with a mobile X-ray detector. The method includes determining an examination region of the examination object, acquiring a position and a location of the examination object and the examination region by way of an optical position determining system, localizing the examination region, ascertaining a field point of the central ray of the X-ray source and a collimator size of the X-ray source based on the localized examination region, and automatic positioning of the X-ray source based on the field point and the collimator size.

Certain embodiments provide a system for calibrating an X-ray image. The system may receive an X-ray image of an anatomical part of a patient. The system may further receive a 3-D surface scan of a surface of the patient where the anatomical part is located. The system may derive a measurement correction to apply to measurements of the X-ray image based on the 3-D surface scan. The measurement correction may account for: an orientation of the patient with respect to the X-ray detector plate, a first distance between the patient and the detector plate, or a second distance between the patient and an X-ray source used to generate the X-ray image. The system may further determine a corrected measurement of the anatomical part based on the measurement correction and a measurement taken from the X-ray image.
