Research focus

Research

The department's research covers topics from the fields of general radiology and medical physics in veterinary medicine.

 

There are three main areas of focus:

 

Application and optimisation of imaging techniques in veterinary medicine.

The research work is carried out in close cooperation with the clinics of the University of Veterinary Medicine. It is carried out in the fields of imaging with ionising radiation (digital radiography, computer tomography (CT), micro-CT), magnetic resonance imaging (MRI) including functional MRI and passive infrared thermography (passive IRT).

 

The aim of these examinations is usually to answer the question,

whether an imaging technique is in principle suitable for use in a clinical setting, or

whether an imaging technique can be used for a specific indication in routine clinical practice, or

to what extent an imaging procedure already used in clinical routine can be optimised (e.g. with regard to image quality and radiation protection).

 

Computer simulations and modelling for veterinary issues

In order to understand fundamental physical processes within living organisms, mechanical, thermal or electrical processes in animals are simulated in the computer with the help of so-called finite element analysis within the framework of interdisciplinary research projects. The research work is carried out in close cooperation with other institutions at the University of Veterinary Medicine.

 

They mainly concern simulations of

of the mech. stresses and deformations in the horse's bite during chewing,

of heat propagation and distribution in the horse's tooth during dental treatment,

animal welfare-friendly stunning and killing of fish (e.g. simulation of the current density distribution in the brain during electric stunning),

the humane stunning and killing of suckling piglets (e.g. simulation of the current density distribution in the brain and heart during the application of electric current).

In addition to a better understanding of physiological and pathological processes in animals, the simulations also lead to a narrowing of the range of variation of relevant parameters in animal experiments and thus to a reduction in the number of animal experiments.

 

Research in the fields of radiation protection and dosimetry of ionising radiation

The increasing use of imaging techniques with ionising radiation in veterinary medicine on the one hand, and the continuing trend towards lowering dose limits for occupationally exposed persons on the other, raise questions with regard to radiation protection and dosimetry of ionising radiation. The research work is often carried out in close cooperation with the clinics of the University of Veterinary Medicine.

 

They are mainly carried out in the fields of

Radiation exposure of radiological staff and animal attendants during radiological procedures and

optimisation of physical-technical parameters in the evaluation of dosimeters (e.g. thermoluminescence dosimeters).

The goals of this research are usually the evaluation and improvement of the radiation protection situation in the use of imaging procedures with X-rays.

 

The research projects often also include the development and/or application of electronic measurement technology (e.g. sensors and signal amplifiers).
