  7. 10. A flexible resonance sensor system for detection of cancer tissue : evaluation on silicon

    Author : Anders P. Åstrand; Britt Andersson; Ville Jalkanen; Olof A. Lindahl; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The most common form of cancer among men in Europe and the US is prostate cancer. When a radical prostatectomy has been found necessary, it is of interest to examine the prostate, as tumour tissue on the capsule might indicate that the cancer has metastased. This is commonly done by a microscope-based morphometric investigation. READ MORE
