1. A method of determining a configuration setting for use by an associated medical imaging system including an x-ray source and an x-ray detector mounted on a gantry and an x-ray source collimator operable to shape an x-ray beam emitted by the x-ray source to determine a position of a marker device attached to an object, wherein at least one of the x-ray source and the x-ray detector is moveable along the gantry, the configuration setting of the medical imaging system comprising positions of the x-ray source and the x-ray detector and a parameter setting of the x-ray source collimator, the associated medical imaging system being operable to capture a marker image showing the marker device, the method comprising:
acquiring patient position data representative of a position of a patient relative to the medical imaging system;
acquiring approximate marker position data representative of an approximate position of the marker device relative to the medical imaging system; and
calculating the configuration setting of the associated medical imaging system from the patient position data, the approximate marker position data and based on a trade-off between:
a first criterion comprising minimizing a radiation exposure on the patient when capturing the marker image; and
a second criterion comprising at least one of:
maximizing a visibility of the marker device in the marker image; and/or
maximizing an expected imaging quality of the marker device in the marker image,
wherein the calculated configuration setting is usable by the associated medical imaging system to capture, based on the calculated configuration setting, a marker image that shows the marker device for determining the position of the marker device attached to the object.
