Fast pseudo-CT synthesis from MRI T1-weighted images using a patch-based approach
MRI-based bone segmentation is a challenging task because bone tissue and air both present low signal intensity on MR images, making it difficult to accurately delimit the bone boundaries. However, estimating bone from MRI images may allow decreasing patient ionization by removing the need of patient-specific CT acquisition in several applications. In this work, we propose a fast GPU-based pseu...
متن کاملFuzzy clustering Approach in segmentation of T1-T2 brain MRI
−Segmentation is a difficult and challenging problem in the magnetic resonance images, and it considered as important in computer vision and artificial intelligence. Many researchers have applied various techniques however fuzzy c-means (FCM) based algorithms is more effective compared to other methods. In this paper, we present a novel FCM algorithm for weighted bias (also called intensity in-...
متن کاملNew Pseudo-CT Generation Approach from Magnetic Resonance Imaging using a Local Texture Descriptor
Background: One of the challenges of PET/MRI combined systems is to derive an attenuation map to correct the PET image. For that, the pseudo-CT image could be used to correct the attenuation. Until now, most existing scientific researches construct this pseudo-CT image using the registration techniques. However, these techniques suffer from the local minima of the non-rigid deformation energy f...
متن کاملPatch-based generation of a pseudo CT from conventional MRI sequences for MRI-only radiotherapy of the brain.
PURPOSE In radiotherapy (RT) based on magnetic resonance imaging (MRI) as the only modality, the information on electron density must be derived from the MRI scan by creating a so-called pseudo computed tomography (pCT). This is a nontrivial task, since the voxel-intensities in an MRI scan are not uniquely related to electron density. To solve the task, voxel-based or atlas-based models have ty...
متن کاملPseudo-subarachnoid hemorrhage demonstrated by T2*-weighted gradient echo MRI.
was referred to the neurology department for comatose state with brainstem dysfunction. Non-contrast brain CT showed diffuse cerebral edema with subarachnoid hemorrhage (SAH)-like appearance (Fig. 1A). A lumbar puncture was not carried out because of the brain edema which was revealed in CT examination. T2*-weighted gradient-echo MRi revealed enlarged subarachnoid vessels that were not consiste...
