A common tool for tissue ablation is the use of heat. For the imILT technique investigated in this project, the heat is induced by the usage of laser light. The light is absorbed by the tissue and is thus turned into heat, the amount absorbed depends on the optical properties of the tissue, such as absorption and scattering. In imILT such as in other laser based ablation techniques, optical fibers
The ground volume is penetrated by a duct system for injection and extraction of heat. The heat transfer properties between the ground and such a system is here characterized by a heat transfer length. The heat exchange between the soil and the ducts is represented by a heat source/sink distribution in the storage region.
In this paper, the authors present the characterization experiments of a 20 fs vacuum ultraviolet beam from a high harmonic generation source. The beam hits a silicon sample and passes a triple reflection gold polarizer located inside an ultrahigh vacuum chamber. The polarizer's Malus curve was obtained; the total acquisition time for each point of the curve was 30 s. This aims to be the first vac
Purpose: Volumetry of cerebral ventricles is a far more sensitive measure for shunt-induced reduction of ventricular size than traditional 2-dimensional (2D) measures, such as Evans index. However, available ventricle segmentation methods are time-consuming, resulting in limited use in clinical practice. Quantitative MRI (qMRI) obtains objective measurements of physical tissue properties, enabling
