1. Phase-Contrast Imaging, Towards G2-less Grating Interferometry With Deep Silicon
University essay from KTH/FysikAbstract : Conventional phase-contrast imaging entails stepping an analyser grating across the detector to resolve the interference pattern caused by the x-rays after passing through a series of gratings in a so-called Talbot-Lau interferometer. However, the analyser grating in the interferometer poses a challenge, not only due to the machinery and alignment required but also due to each exposure delivering a dose to the subject. READ MORE

2. Rapid Preparation of Soft Tissue for X-ray Virtual Histology
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : When removal of primary tumors is performed by surgery, the surgeon andthe patient would benefit from using intraoperative feedback to evaluate thetumor resection margin. If intraoperative feedback is not provided there isadditional risk of treatment of the tumor. READ MORE

3. Black-Blood Phase Contrast Magnetic Resonance Imaging using Stimulated Echo Acquisition Mode : Pulse Sequence Development
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Doppler echocardiography is the conventional method for measurement of myocardial motion. However, the same clinical parameters can be measured with phase contrast magnetic resonance imaging (MRI). READ MORE

4. Automation of Kidney Perfusion Analysis from Dynamic Phase-Contrast MRI using Deep Learning
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Renal phase-contrast magnetic resonance imaging (PC-MRI) is an MRI modality where the phase component of the MR signal is made sensitive to the velocity of water molecules in the kidneys. PC-MRI is able to assess the Renal Blood Flow (RBF), which is an important biomarker in the development of kidney disease. READ MORE

5. Artificial intelligence for segmentation of nuclei from transmitted images
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : State-of-the-art fluorescent imaging research is strictly limited to eight fluorophore labels duringthe study of intercellular interactions among organelles. The number of excited fluorophore colorsis restricted due to overlap in the narrow spectra of visual wavelength. READ MORE
