The workshop staff consists of eight highly skilled technicians, who are working on various issues from research and teaching. The services comprise the development of new medical and scientific devices and equipment, the supervision of the students’ practical course at the Institute of Physiology, repair service for laboratory equipment and advisory service on technological matters.

Development projects

Development and construction of a cryogenic camera holding with adjustment used for episcopic imaging of biodistribution of injected fluorescent dyes in complete frozen, post-mortem mice to determine the distribution of the fluorescent dyes depending on the injection time (Anesthesiology and Intensive Care Medicine).
Development and construction of a brain slice chamber with temperature control for measuring local field potentials and long term potentiation in urgent hippocampal brain slice preparations (Neurology).
For the systematic evaluation of the correlation between temperature and CT value, a temperature-regulating water circulation system was developed and applied to a CT Revolution (GE Healthcare) with Gemstone Spectral Imaging Technology (GSI) and two reconstruction methods (iterative and deep learning-based) (Diagnostic and Interventional Radiology/Translational research).
An easy-to-handle measuring setup for the reproducible, fast and precise measurement of magnetically induced torques caused by ferromagnetic materials and currents in lead wires (active implants) at a static magnetic field of 1.5 T and 3 T was developed that can simplify, accelerate and further develop the ASTM F2213 standard (Diagnostic and Interventional Radiology/Translational research) .
Manufacture of a placenta perfusion chamber for the use of the ex vivo placenta perfusion method (Obstetrics/Placenta Lab).
Development and construction of a mechanical rotating unit for a radar system for UWB microwave imaging to detect breast cancer (Experimental Radiology).
Development and construction of a device for position calibration of a video image to simultaneously collect motion analysis data for video triggered defined head movements. (Otorhinolaryngology).
Development and construction of a measuring device for vibration measurements for evaluating the osseointegration of implants (Otorhinolaryngology).
Development and construction of an AOD invivo stage (Neurology).
Development and construction of yellow and blue laser light sources for channel activation of cells (Physiology II).
Development and construction of trigger electronic (Single-Molecule Microscopy Group).
Manufacture of a measuring phantom for calibration of thermoluminescence detectors for determination of radiation exposure in computed tomography. A first project is the comparison of radiation exposure with imaging on conventional CT and optional 3D-imaging of the angiography robot for patients who are supposed to receive a prostate embolization (Diagnostic and Interventional Radiology).

Equipment

In the mechanics department there are two computerized numerical control (CNC) lathes, three conventional milling machines, three conventional lathes, an electric power shear, a bending machine for synthetic material, a tungsten-inert gas welder, an acetylene welder and several small machine tools.

In the electronics department, two work places for electronics engineering and one for microscopy are located. We work with software systems for mechanical construction, simulation of designed circuits and the layout of circuit boards. Furthermore, software engineering for various microcontrollers is done in-house.
