Physiological Measurements (FMT) at Linköpings universitet was founded in 1972. Head of the group is Professor Per Ask.

The research covers areas from physiological modelling to non-invasive measurements of various physiological parameters. In medical ultrasound, bio-optics, bio-acoustics our main application areas are in the cardiovascular area. In ultrasound development of ultrasound contrast, methods to measure blood perfusion in the heart muscle are performed. Simulation and in-vitro modelling are used. Bio-optical research is performed on photoplethysmography, the origin of this signal and how this signal can be related to blood flow. Furthermore, absorption spectroscopy is used to study the chemical content in fluids and is applied to optimising the dialysis process. A concept in the bio-acoustic research is the intelligent stethoscope where physiologically relevant information is extracted from the signal. Intelligent sensors in home and primary health care is one main area of application.

In our cardiovascular engineering work, Per Ask is responsible for the LiU activities within CORTECH, a Swedish university network for advanced engineering and technologies in cardiovascular medicine. Research groups in Stockholm, Linköping and Lund are involved in the project, which is funded by the Swedish Foundation for Strategic Research. We are also part of the competence center NIMED and the Forum Scientum research school.
