Definitions

  • proximity sensors are used to detect proximity of objects to the C- arm and a collision avoidance action is taken, such as the C-arm is slowed down or its motion is even brought to a halt.
  • a filter module configured to filter said response signal to produce a filtered response signal
  • the apparatus comprises an action module configured to issue an output signal for an object approach action to be taken if the response signal or the filtered response signal fulfils a second condition, in particular crosses a second threshold as measured relative to said new base value.
  • the preferred type of sensor envisaged herein is of the capacitive type, as they have shown to produce reliable results that work well in medical imaging contexts, are relatively low cost, have low power requirements and have high reliability.
  • Certain other types of sensors are not excluded herein and include: inductive, magnetic, infrared, thermal, Hall effect-based, optical or sonic-based (in particular, ultrasonics-based), etc. These types of proximity sensors are distinguishable by the physical quantity onto which the object approach is modulated upon.
  • the proposed system is unlike this because the proposed ACU system uses a dynamic thresholding scheme.
  • the baseline varies in a specific way and whether or not an action is taken does not only depend on a specific baseline deviation but also on the magnitude of the baseline itself, that is, whether the ACS is in an excited or proximity state.
