Analysis Of Magnetic Resonance Imaging ( Mri ) Based Three...

Magnetic Resonance Imaging (MRI) based three dimensional reconstruction has been used successfully to evaluate the female pelvic floor muscles and tissues in women with and without pelvic floor dysfunction [1, 2]. Furthermore, MR based 3D reconstructed models have been used to generate finite-element and element free computational models suitable for simulating vaginal child-birth [3, 4], offering insight into risk factors for childbirth related pelvic floor injury. The Finite Element Method has also been used to evaluate anterior vaginal wall support, and the mechanisms underlying cystocele formation [5]. Precise segmentation of pelvic magnetic resonance images (MRI) is an important step in building the three-dimensional (3D) reconstructed structural models suitable for computational analysis. Segmentation consists of outlining each organ or tissue of interest from the underlying grayscale images on each slice in the dataset. The 3D reconstructed models are currently generated from manually segmented label-maps, which currently require multiple hours of tedious manual segmentation to produce each reconstructed 3D model. This manual segmentation bottleneck limits the number of computational models that can be reliably produced in a timely manner, thereby limiting the number of study subjects available for the kind of statistical comparisons that can potentially lead to clinically meaningful insight. In addition, the structures of the female pelvic floor are very complexShow MoreRelatedSinus And Skull Base Surgery1628 Words   |  7 Pagessurrounding FESS have resulted in intra-operative Image-Guidance Systems (IGS) to improve outcomes in complex skull base procedures. A principal limitation of the endoscopic endonasal approach is the availability of only a two-dimensional view, with surgeons instead localising instruments based partly on their depth of penetration and tactile sensation. The restricted nat ure of the sinonasal tract and the complex arrangement of adjacent vital structures (carotid artery, optic nerve, dura mater and brain), aRead MoreAnalysis : Convolution Of Kernel Matrixes 1949 Words   |  8 PagesMatrixes Abstract I. INTRODUCTION Medical imaging is a technique used to recreate images coming from different devices. These visualizations of the interior structure of the body are of great importance in regards to the medical field, because these images are used for diagnosing or treating several diseases. In addition, medical imaging is a powerful tool that helps to in analyzing mechanical and chemical properties of an organ or tissue. In fact, medical imaging made it possible to identify diverseRead MoreComputer Aided Diagnosis Systems For Infectious Diseases Essay1998 Words   |  8 Pagesradiology spanning from development of computer aided diagnosis systems for infectious diseases to general image analysis techniques in MRI, CT, PET, and histology images, and development of image enhancement and reconstruction methods both in clinical, pre-clinical, and technical fields [11-65].

The initial aim is to establish a tentative diagnosis of pulmonary hypertension, to assess its severity and to identify the underlying aetiology. Subsequently non-invasive imaging techniques are used in monitoring disease progression as well as response to treatment in patients with
