Abstract:
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.
