Medical Laser-Tissue Interactions
Monday, 27 January 2025 • 8:30 AM - 12:30 PM
As an engineer, scientist or technician working with lasers in the medical field, you like to educate your medical colleagues how to use the laser safely on patients. Educating them with formulas, graphs and models turns them off. This course is a visual spectacle full of video clips, showing the effects of various medical lasers in simulations and tissues using high speed and thermal imaging techniques.
Using simple deduction, the many parameters of influence can be brought back to a simple equation: the amount of energy that is deposited in a particular volume (~absorption depth x beam diameter) of tissue within a particular length of time. With this background, the dynamics of the ablation process of tissue, the characteristics of laser delivery devices, the effect of focused beams and short lasers pulses will explained.
Students will be provided with a set of rules of thumb to explain physicians what tissue effects they can expect and use medical lasers safely.
Learning Outcomes
- describe the basics of interaction of various medical lasers with tissues depending on the wavelength, power/energy and pulse time
- predict the resulting thermal and mechanical effects in tissue depending on the settings of laser exposure
- describe the influence of the laser delivery system on the laser tissue effect
- estimate and be aware of potential dangers of laser light interaction and how to take safety measures
- identify a wide range of medical laser applications
- describe the benefit of using lasers above other medical equipment
- demonstrate to physicians how to use medical lasers safely
- explain practical do and don’t for laser applications
- discriminate between the effects of various lasers in tissue
Audience
Engineers, scientists and technicians working in the medical field (hospitals, institutes or companies) with physicians using medical lasers. Physicians are also very welcome. Undergraduate training in science is assumed.
Instructor
Rudolf M. Verdaasdonk - Univ. Twente (Netherlands)
Rudolf M. Verdaasdonk is chair of Health Technology Implementation at the University of Twente in the Netherlands and professor of Physics and Medical Technology and has been working in close collaboration with the clinical professionals. He has extensive practical experience in the OR assisting in laser surgery for over 30 years. For his research, he has developed special imaging techniques to study the interaction of lasers with the patient in view of safety, treatment quality and development of new applications. The images have been used for education and training of medical professionals. He is active in patient safety, innovation and valorisation of new medical technologies with several patents and devices being commercialized. He has authored over 200 papers, proceedings and book chapters on medical lasers, surgical devices and imaging techniques for diagnostics. He is fellow of SPIE.
