Spectroscopic optical coherence tomography – theory and medical applications
Patrick Steiner
Abstract Modern medicine has always shown a need for imaging techniques that are easy to use, non-invasive and therefore painless and safe for the patient but still provide the highest possible resolution both spatially and in time. Widespread medical imaging methods such as X-ray, computer tomography (CT) or magnetic resonance imaging (MRI) are well developed but all suffer from unwanted side effects such as dangerous irradiations or high costs. A new approach to the challenge of a simple, high resolution imaging technique is called optical coherence tomography (OCT). OCT systems are generally used in ophthalmology but in the last couple of years, OCT has also been introduced to other areas such as fingerprint screening or dentistry with further areas are being subject of research worldwide. Spectroscopic optical coherence tomography (SOCT) extracts characteristic spectral information, such as wavelength dependant attenuation coefficients from the sample. Those information are enclosed in the OCT signal and can be extracted using appropriate post-processing algorithms. The extracted spectral information pave the way for an in vivo assessment of physiological parameters such as blood oxygen saturation, blood sugar levels and cancer detection which makes SOCT a very promising field for further breakthroughs in non-invasive in vivo monitoring of patients in medical treatment.
Biography Patrick Steiner was born in Biel, Switzerland on May 25,
1983. He started his Bachelor in electrical engineering at the ETH
Zurich in October 2003, which he finished beginning of 2008. There, he
focused on high voltage electronics and mechatronic systems. Since then
he is working on his master in biomedical engineering at the ETH Zurich. |
