ABSTRACT:
A method of avoiding collisions with components of medical diagnostic imaging system includes defining a plurality of imaging system components as wire frame representations having vertices. The objects in the imaging system are defined in a common coordinate system using transform matrices for the imaging system components. An operator initiates movement of the imaging system components and position and motion input signals are provided to a controller. The transform matrices for imaging system components are updated and a final transform is computed in response to the input signals for the imaging system components, the final transform indicative of a position of imaging system components at a predetermined time interval. The final transform is applied to the wire frame representation generating a new position for the wire frame and a determination is made as to whether a collision is occurring between any of the plurality of imaging system components using the new wire frame positions.
