Development of a Tracking Dual-plane Fluoroscope for assessing musculoskeletal and orthopaedic kinematics: Implementation of a tracking system – Feedback control algorithm
Development of a Tracking Dual-plane Fluoroscope for assessing musculoskeletal and orthopaedic kinematics:
Implementation of a tracking system – Feedback control algorithm
**Background**
The Dual-plane tracking Fluoroscope (DuoFluo) project is a flagship project for the Interdisciplinary Master Project Platform (IMPP) that will employ the interdisciplinary expertise of Master students from HEST, MAVT, ITET and INFK. The idea is to create a tracking dual-plane video-fluoroscope for the accurate real-time assessment of 3D kinematics of natural, pathological or implanted joints in vivo and during complete cycles of a wide range of functional activities, including low- and high-speed motion, all while the subject is moving freely. Utilising considerable sponsorship and funding, the aim is to design and eventually build the large, high-speed tracking device in a collaborative effort across departments in a project that allows combined supervision and grading of Master theses working together to achieve a unique and clinically relevant measurement technology.
**Project**
As the actual field of view in a dual plane fluoroscope system is very limited, a real-time tracking system needs to be implemented. Based on the already evaluated sensor system (partner section of study), a feedback loop should be integrated. Through respecting to the system’s weight and available power, the system should be able to track the subject’s measured movement with as little delay as possible. This project is therefore required to develop fast control algorithms to process the combined position signals from the measurement system and the DuoFluo fluoroscopes, and convert these into controlled motor commands for continued tracking of the subject’s movement.
**Position**
6-month Master Thesis for ITET student or similar
**Tasks**
10 % Literature review
40 % Analysis of the whole setup and design of a feedback loop
40 % Implementation of a tracking algorithm
10 % Preparation of report and presentation
**Skills**
- The successful candidate will be required to work closely in an interdisciplinary team, and should therefore possess excellent communication skills
- Good background in control theory, and design of feedback systems

The aim of this part of the project is to design a feedback loop which makes the system stable and fast. Together with the system software design (see position “User interface”), safety procedures should be considered and implemented.

As a flagship project of the new Interdisciplinary Master Project Platform (IMPP), there are a number of considerations and regulations that need to be respected. Each student participating in an IMPP project needs to be graded individually and competently from a Professor with the appropriate background (i.e. from the student’s home department). As a result, each student needs to ensure that a cooperating Prof from their home department would be happy to allow their participation in this project, as well as co-supervise (advise when needed), and help grade the student’s work.
