Internship: patient motion compensation for needle placement system

  • medical
  • robots
  • needle placement
  • patient motion
  • demonstrator

Educational level: bachelor/academic

Duration: 6 months


Within the DEMCON organization, the business unit Medical Systems DEMCON develops and realizes medical devices for diagnosis, therapy, care and self-care. Applications are found in fields including surgery, therapy and diagnostics. Examples include a needle positioning system under CT guidance, an operating system for eye surgery, a hand scanner for rheumatoid arthritis, a ventilator or a hearing aid. Besides contract R&D activities for clients, the Medical Systems business unit develops and sells devices and technology to end-users via daughter companies such as Finapres, Macawi and DEMCON Medical Robotics.



Within DEMCON Medical Robotics a Needle Positioning System (NPS) under CT guidance has been developed. This system is able to support the insertion of a biopsy or ablation needle into a target tumor in a precise and first time right manner. See also

A challenging problem for such a Needle Positioning System is the movement of the target tumor due to movement of the patient, in particular due to breathing. This can be done by respiratory hold, for example by instructing the patient, but it would be advantageous if the system could adapt for these movements. In a first internship several concepts are defined for motion compensation during needle placement. The most promising concepts should be designed into a demonstrator, which can be investigated for further development.



Design and build a demonstrator of a  motion compensation concept for a needle placement system under CT guidance.

During this assignment you will be working on:

  • system specifications of a patient motion compensation system
  • design of a demonstrator for a patient motion compensation system
  • realization and assembly of the demonstrator
  • verification against the system requirements
  • proposals for further development

Depending on the length of your assignment, you will be involved in multiple stages of medical product development from specifications, concept design, detailed engineering, realization and verification and validation.

At the start of the internship, a concrete plan will be formulated to guarantee that the scope of the assignment is feasible within the available timeframe.
