Automatic detection of the Anterior and Posterior Commissures from T1-weighted images

چکیده
Introduction Frame-based interventional MRI often relies on the manual selection of the anterior commissure and of the posterior commissure (AC-PC) line that are often considered as landmarks for the localization of neuroanatomic targets [1], as, for instance, for guiding the implantation of electrodes within the subthalamic nuclei dedicated to deep stimulation in the treatment of Parkinson’s disease [2]. In this abstract, we present a fast and fully automatic identification of the AC and PC points from T1– weighted images, thus leading to an automation of the image processing step during the neurosurgery planning. The method is based on the analysis of the mid-sagittal plane (MSP) using parameterless prior knowledge.

Magnetic resonance imaging of feline eye
The purpose of this study was to investigate magnetic resonance imaging (MRI) of the normal feline eyeand optic nerves using T1-weighted and T2-weighted images. A total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. Magnetic resonance imaging data werecollected using GEMSOW (Philips) at a magnetic field strength of 1.5 T. Dorsal, sagittal, a...
متن کاملModel-based automatic detection of the anterior and posterior commissures on MRI scans
The projections of the anterior and posterior commissures (AC/PC) on the mid-sagittal plane of the human brain are important landmarks in neuroimaging. They can be used, for example, during MRI scanning for acquiring the imaging sections in a standard orientation. In post-acquisition image processing, these landmarks serve to establish an anatomically-based frame of reference within the brain t...

متن کاملFully automatic detection of deep white matter T1 hypointense lesions in multiple sclerosis.
A novel method is presented for fully automatic detection of candidate white matter (WM) T1 hypointense lesions in three-dimensional high-resolution T1-weighted magnetic resonance (MR) images. By definition, T1 hypointense lesions have similar intensity as gray matter (GM) and thus appear darker than surrounding normal WM in T1-weighted images. The novel method uses a standard classification al...
متن کاملReducing Light Change Effects in Automatic Road Detection
Automatic road extraction from aerial images can be very helpful in traffic control and vehicle guidance systems. Most of the road detection approaches are based on image segmentation algorithms. Color-based segmentation is very sensitive to light changes and consequently the change of weather condition affects the recognition rate of road detection systems. In order to reduce the light change ...
