Johan Richter

My focus is on identification of brain tumour tissue and its differentiation from healthy brain tissue with optical methods that can be used during surgery. I am a senior consultant at Linköping University Hospital and affiliated with IMT.

Research

Two doctors is standing in front of a screen where a disection of a brain is visible.

Neuroengineering

Neuroengineering is a cross-disciplinary research area where engineering meets neuroscience. New methods, tools and techniques are developed and translated for clinical use. The research contributes to new knowledge of the human brain.
Optical guidance in neuro surgery

Optical guidance in neurosurgery

Optical techniques as laser Doppler flowmetry (LDF), diffuse reflectance spectroscopy (DRS) and fluorescence systems, and their related measurement probes, are adapted and translate for use during the neurosurgery.

Intraoperative MRI in Neurosurgery

Magnetic resonance imaging (MRI) and biomedical optic systems are used for nueroguidance during brain tumor biopsies and resection. DBS implantation and for investigation of cerebral bleedings of neurointensive care patients.
