Brain Structural Changes Caused by Autism Spectrum Disorder Based on Volumetric Analysis of Magnetic Resonance Images: A Review Study
Background and purpose: Autism spectrum disorder (ASD) is a psychiatric disorder which occurs in early years of life and causes various individual and social problems. Early detection of autism would help in taking necessary precautions and preventing its adverse side effects. Methods & Materials: In this paper, we reviewed the articles that have investigated brain structural changes caused by...
متن کاملValidation of model-based brain shift correction in neurosurgery via intraoperative magnetic resonance imaging: preliminary results
The quality of brain tumor resection surgery is dependent on the spatial agreement between preoperative image and intraoperative anatomy. However, brain shift compromises the aforementioned alignment. Currently, the clinical standard to monitor brain shift is intraoperative magnetic resonance (iMR). While iMR provides better understanding of brain shift, its cost and encumbrance is a considerat...
متن کاملA Two-Dimensional Convolutional Neural Network for Brain Tumor Detection From MRI
Aims: Cancerous brain tumors are among the most dangerous diseases that lower the quality of life of people for many years. Their detection in the early stages paves the way for the proper treatment. The present study aimed to present a two-dimensional Convolutional Neural Network (CNN) for detecting brain tumors under Magnetic Resonance Imaging (MRI) using the deep learning method. Methods & ...
متن کاملFabrication of New 3D Phantom for Measuring Geometric Distortion in Magnetic Resonance Imaging System
Introduction: Geometric distortion is a major shortcoming of magnetic resonance imaging (MRI), which has an important influence on the accuracy of volumetric measurements, an important parameter in neurology and oncology. Our goal is to design and construct a new three- dimensional phantom using a 3D printer in order to measure geometric distortion and its reproducibility in...
متن کاملComposite Match Index with Application of Interior Deformation Field Measurement from Magnetic Resonance Volumetric Images of Human Tissues
Whereas a variety of different feature-point matching approaches have been reported in computer vision, few feature-point matching approaches employed in images from nonrigid, nonuniform human tissues have been reported. The present work is concerned with interior deformation field measurement of complex human tissues from three-dimensional magnetic resonance (MR) volumetric images. To improve ...
