1. 21. A path along deep learning for medical image analysis : With focus on burn wounds and brain tumors

   Författare :Marco Domenico Cirillo; Anders Eklund; Veronika Cheplygina; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deep learning; Medical image analysis; Burn wounds; Brain tumors; Image classification; Image segmentation; Image augmentation; CNNs; GANs;

   Sammanfattning : The number of medical images that clinicians need to review on a daily basis has increased dramatically during the last decades. Since the number of clinicians has not increased as much, it is necessary to develop tools which can help doctors to work more efficiently. LÄS MER

3. 22. Virtual Reality for Enriched Rehabilitation of Stroke Patients with Spatial Neglect : Diagnostics and the Rehabilitation Effect on Spatial Attention and Neuronal Activity

   Författare :Helena Fordell; Jan Malm; Anders Eklund; Hanne Krarup Christensen; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stroke; spatial neglect; rehabilitation; virtual reality; enriched environment; fMRI;

   Sammanfattning : Background: Approximately a third of all stroke patients develop spatial neglect, a debilitating symptom associated with poor outcome. Spatial neglect is clinically defined as a deficit in processing and responding to stimuli presented on the contralesional side of the body, or the space surrounding that side of the body. LÄS MER

4. 23. Advanced analysis of diffusion MRI data

   Författare :Xuan Gu; Anders Eklund; Tim Dyrby; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion MRI; Distortion Correction; Deep Learning; Uncertainty Estimation;

   Sammanfattning : Diffusion magnetic resonance imaging (diffusion MRI) is a non-invasive imaging modality which can measure diffusion of water molecules, by making the MRI acquisition sensitive to diffusion. Diffusion MRI provides unique possibilities to study structural connectivity of the human brain, e.g. LÄS MER

5. 24. Applanation Resonance Tonometry for Intraocular Pressure Measurement

   Författare :Per Hallberg; Olof A. Lindahl; Anders Eklund; Christina Lindén; Per Ask; Umeå universitet; []
   Nyckelord :Physics; Resonance; applanation; tonometry; glaucoma; Goldmann; biomechanical; Intraocular; ART; Fysik; fysik; Physics;

   Sammanfattning : Elevated intraocular pressure (IOP) is one of the major risk factors for glaucoma. Since glaucoma is a leading cause of blindness, reliable methods for measuring the IOP are important. This doctoral dissertation presents a new method, applanation resonance tonometry (ART), for measurement of IOP. LÄS MER

7. 25. Fluid dynamic principles for analysis of intracranial pressure control : application towards space medicine and hydrocephalus

   Författare :Petter Holmlund; Anders Eklund; Sara Qvarlander; Jan Malm; Marek Czosnyka; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intracranial pressure; posture; cerebrospinal fluid; microgravity; venous collapse; internal jugular vein; fluid dynamics; venous pressure; spaceflight-associated neuro-ocular syndrome; hydrocephalus; mathematical modeling; ultrasound; magnetic resonance imaging;

   Sammanfattning : Intracranial pressure (ICP) is an important component of the fluid dynamic environment of the brain and plays a central role with regards to the maintenance of normal cerebral blood flow and neuronal function. However, many regulatory mechanisms controlling the ICP are still poorly understood. LÄS MER
