ITK is an open-source software toolkit for performing registration and segmentation. Segmentation is the process of identifying and classifying data found in a digitally sampled representation. Typically the sampled representation is an image acquired from such medical instrumentation as CT or MRI scanners. Registration is the task of aligning ...
The simplest approach is to model medical images as deformed versions of a single template image. For example, anatomical MRI brain scans are often mapped to the MNI template [35] as to represent all the brain scans in common coordinates. The main drawback of a single-template approach is that if there are significant differences between the ...
(a) CT scan of the head. (b) MRI machine. (c) PET scans produce images of active blood flow and physiological activity in the targeted organ or organs. (d) Ultrasound technology to monitor pregnancy. Medical imaging is a range of imaging techniques and technologies that enables clinicians to visualize the internal structures of the human body.
There are many applications of U-Net in biomedical image segmentation, such as brain image segmentation (''BRATS'' [8]) and liver image segmentation ("siliver07" [9]) as well as protein binding site prediction. [10] U-Net implementations have also found use in the physical sciences, for example in the analysis of micrographs of materials.
Volume segmentation of a 3D-rendered CT scan of the thorax: The anterior thoracic wall, the airways and the pulmonary vessels anterior to the root of the lung have been digitally removed in order to visualize thoracic contents: – blue: pulmonary arteries – red: pulmonary veins (and also the abdominal wall) – yellow: the mediastinum
Body center rendered in MeVisLab. MeVisLab features include: [3] [4] [5] Image processing with the MeVis Image Processing Library (ML): The ML is a request-driven, page-based, modular, expandable C++ image processing library supporting up to six image dimensions (x, y, z, color, time, user dimensions).
In imaging genomics, radiogenomics can be used to create imaging biomarkers that can identify the genomics of a disease, especially cancer without the use of a biopsy. Various techniques for dealing with high-dimensional data are used to find statistically significant correlations between MRI , CT , and PET imaging features and the genomics of ...
To determinate whether there is a need for PVE the FLR needs to be measured. There are various imaging methods used in order to measure the liver volume such as contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI) [11] and the FLR can be traced either manually or using automatic or semi-automatic segmentation tools ...
