Since the discovery of X-rays by Wilhelm Conrad Röntgen in 1895 imaging systems have become an integral and indispensable part in science and medicine. By now they are an essential key technology in modern biomedicine. Besides the classical X-ray projection and the more recently introduced computed tomography (CT), imaging systems encompass also devices based on magnetic resonance or ultrasound waves.
Continuing on the course Biomedical Imaging I , held in the winter semester 2019/2020, the purpose of this course is to introduce the physical principles, fundamental properties and technical concepts of imaging systems as they are applied today in medicine and physics. Applications and current developments will be presented and should serve to reinforce understanding of this field of imaging science. The focus of this course will be on systems employing non-ionizing radiation. It aims for students of physics, photonics, material science, medicine as well as interested students at the level of the fifth semester or higher.
Techniques and Applications in Experimental MRI - Basics and Recent Developments
Techniques and applications in experimental MRI --- Foundations and current results
seminar date and time: Wednesday, bi-weekly; start on 28.04.2021, time: 15:15 – 16:45 Uhr
All talks will be held as zoom-meeting. To keep the interactive style, discussions after the talk are explicitly encouraged so please try to get hold of a microphone to join. You can also ask questions through the chat function.

MR Safety Instructions
Dr.-Ing. Daniel Güllmar
Dr. rer. nat. Karl-Heinz Herrmann
Dates and time: on request
Duration: depending on required modules (MRI, S1 GenTSV, Small Ainmal MRI,.. ) typically 30-120min
Location: Due to Corona restrictions no normal lectures (and we might never restart them, see moodle below)..
Moodle self study: We offer a modular moodle lecture for self study in English.
As a member or student of UKJ or FSU, you can login to the FSU moodle using your FSU login (probably your eduroam login and the mail login for your acount). If you are member of UKJ, please find out how to access your uni-jena.de accounts or if you have to activate your FSU accounts first.
If you are neither associated with UKJ or FSU, please Email me karl-heinz.herrmann(at)med.uni-jena.de and ask for a external access. Please add a few lines stating why, which group you are working with and your project. I will then register you for your Email address. You will have to login into the moodle server as well, otherwise I cannot add you to the lecture.
To finish your moodle lecture there will be a quick on-site Testat, and some papers to sign. That is also your opportunity to ask any of your questions directly. Please contact Daniel Güllmar or Karl-Heinz Herrmann for an appointment.
You have no valid MR safety unless that paperwork is completed and signed!
