1. 1. Experimental set-up for near infrared fluorescence measurements during surgery

   Kandidat-uppsats, Biomedicinsk instrumentteknik; Tekniska högskolan

   Författare :Pascal Behm; [2013]
   Nyckelord :;

   Sammanfattning : In case a tumour grows in a tissue close to the lymphatic system, biopsies of the first draining lymph nodes connected to the tumour, also known as sentinel lymph nodes, allow determining if the cancer has already metastasized. Lymph node mapping is used in oncology surgery to find the patients lymph nodes connected to the tumour. LÄS MER

3. 2. Blood interference in fluorescence spectrum : Experiment, analysis and comparison with intraoperative measurements on brain tumor

   Kandidat-uppsats, Linköpings universitet/Biomedicinsk instrumentteknik; Linköpings universitet/Tekniska högskolan

   Författare :Shannely Lowndes; [2010]
   Nyckelord :autofluorescence; blood absorption spectra; diffuse reflection spectroscopy; optical touch pointer; intraoperative optical measurements;

   Sammanfattning : The optical touch pointer (OTP), a fluorescence spectroscopy based system, assists brain surgeons during guided brain tumor resection in patients with glioblastoma multiforme (GBM). After recording and analyzing the autofluorescence spectrum of the tissue, it is possible to distinguish malignant from healthy brain tissue. LÄS MER
