Tidskriftsartikel (refereegranskat)abstract
- Resonance sensor systems have been shown to be able to distinguish between cancerous and normal prostate tissue, in vitro. The aim of this study was to improve the accuracy of the tissue determination, to simplify the tissue classification process with computerized morphometrical analysis, to decrease the risk of human errors, and to reduce the processing time. In this article we present our newly developed computerized classification method based on image analysis. In relation to earlier resonance sensor studies we increased the number of normal prostate tissue classes into stroma, epithelial tissue, lumen and stones. The linearity between the impression depth and tissue classes was calculated using multiple linear regression (R(2) = 0.68, n = 109, p < 0.001) and partial least squares (R(2) = 0.55, n = 109, p < 0.001). Thus it can be concluded that there existed a linear relationship between the impression depth and the tissue classes. The new image analysis method was easy to handle and decreased the classification time by 80%.

Mineralogical-textural characterisation of different apatite-iron ore bodies, Malmberget deposit, Sweden, treated in a sorting process in laboratory scale
- 2010
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The Malmberget apatite iron ore deposit encloses more than twenty ore bodies which are mined separately but are blended in the mine before it is hoisted up to the sorting plant. The geology of the deposit shows metamorphic overprints and strong alteration which makes each individual ore body heterogeneous in its composition. In this study the aim is to be able to identify and quantify important mineralogical and textural characters of each ore body which will be part and impact the upgrading process. Two different ores bodies were processed in order to simulate a dry sorting process by bench scale measurements. The analytical methods for quantitative characterisation were optical microscopy and QEMSCAN®. Preliminary results show both differences and similarities between the ore bodies. The mineralogy composition differs between the ore bodies but the most important mineral associations for both ore bodies are binary magnetite/feldspar and magnetite/FeTi-oxides. The magnetite liberation is high for both ore bodies.
