1. A collision detection and resolution system for resolving a collision state of an x-ray system, the system comprising:
- (a) a user interface configured to receive control signals from an operator for activating a collision state resolution process, and receive further control signals for controlling the movement of the x-ray system in a normal mode of operation;
(b) a first system module configured to control the movement of the x-ray system in the normal mode of operation in accordance with position sensor input data received via the user interface, and determine the movement of the x-ray system in the normal mode of operation in accordance with changing position sensor input data;
(c) a second system module configured to detect a collision state of the x-ray system, stop movement of the x-ray system in response to the detected collision state, and monitor at least one of a current position of the x-ray system, a patient table and a source-image distance (SID) of the x-ray system when the collision state is detected;
(d) a third system module configured to format and store data values corresponding to the most recent movements of the x-ray system in the normal mode of operation, and resolve a detected collision state of the x-ray system in the resolve mode of operation by reading out the stored data values in the resolve mode of operation for use in controlling a reverse trajectory of the most recent movements of the x-ray system; and
(e) storage means for storing the data values corresponding to the most recent movements of the X-ray system in the normal mode of operation.

Abstract
A method and system for detecting a collision state between various elements of an x-ray imaging apparatus and/or a patient when they occur and resolving the collision state by reversing the movement of the x-ray imaging apparatus along the same path traveled which led to the collision state in the first instance.
