Phonocardiographic signals consist of bioacoustic info highlighting the functioning of the heart. Usually there are 2 heart sounds, and other sounds suggest disease. If a third heart sound exists it might be a indication of heart failure while a murmur implies defective
The medical imaging system Sectra PACS from Sectra Imtec contains a 3D mode that can be used for visualising image stacks from e.g. computed tomography. Various structures of human anatomy can be visualised in the 3D mode, but visualisations of the bronchial tree of the lungs rarely become good enough to be useful.
The amount of biomedical information that is disseminated over the Web increases every day. This rich resource is used to find solutions to challenges across the life sciences. The Semantic Web for life sciences shows promise for effectively and efficiently locating, integrating..
Image enhancement in 2 dimension is actually a famous and used approach. However the technologies in image acquisition have developed and these techniques usually offer image volumes in 3 or more dimensions, as in computer tomography, CT and magnetic resonance imaging, MRI.
Bacterial L-asparaginases (E.C.18.104.22.168) are enzymes that catalyze the hydrolysis of L-asparagine to aspartic acid. For the past 30 years these enzymes have been used as therapeutic agents in the treatment of acute childhood lymphoblastic leukemia. The presence of a low rate glutaminase
KTH, Division of Neuronic Engineering, have a finite element model of the head. However, this model does not contain detailed modeling of the brain. This thesis project consists of finding a method to extract brain tissues from T1-weighted MR images of the
Magnetic resonance imaging (MRI) is a very versatile imaging modality which can be used to acquire several different types of images. Some examples include anatomical images, images showing local brain activation and images depicting different types of pathologies. Brain activation is detected
A Riemannian manifold is a mathematical concept that generalizes curved surfaces to higher dimensions, giving a precise meaning to concepts like angle, length, area, volume and curvature. A glimpse of the consequences of a non-ﬂat geometry is given on the sphere, where
Conjugated polymers have been found useful in a wide range of applications such as solar cells, sensor elements and printed electronics, due to their optical and electronic properties. Functionalization with charged side chains has enabled water solubility, resulting in an enhanced interaction
The cardiac wall has complex three-dimensional fiber structures and mechanical properties that enable the heart to efficiently pump the blood through the body. By studying the myocardial strains induced during diastole, information about the pumping performance of the heart and what mechanisms
