Optic disc detection is important in the computer-aided analysis of retinal images. It is crucial for the precise identification of the macula to enable successful grading of macular pathology such as diabetic maculopathy. However, the extreme variation of intensity features within the optic disc and intensity variations close to the optic disc boundary presents a major obstacle in automated op...

ABSTRACT We present an analytical model to identify thin discs in galaxies, and apply this a sample of SDSS MaNGA galaxies. This fits the velocity dispersion fields galaxies with regular kinematics. By introducing two parameters ? related comparison model’s asymmetric drift correction observed gas kinematics ? dominant component galaxy, we classify as ‘disc-dominated, ‘non-disc-dominated’, or ‘...

INTRODUCTION In the large-scale case-control study EPILIFT, we investigated the dose-response relationship between lifestyle factors (weight, smoking amount, cumulative duration of different sports activities) and lumbar disc disease. METHODS In four German study regions (Frankfurt am Main, Freiburg, Halle/Saale, Regensburg), 564 male and female patients with lumbar disc herniation and 351 pa...

This study was to analyse the degeneration of the Retinal Nerve Fiber Layer (RNFL) and optic disc and the relationship between optic nerve damage and the severity of cognitive impairment in patients with Alzheimer’s disease (AD) and Mild Cognitive Impairment (MCI). The RNFL thickness and optic disc variables were assessed by optical coherence tomography in patients with MCI and AD and control s...

OBJECTIVE To determine the correspondence between optic disc margins evaluated using disc photography (DP) and optical coherence tomography (OCT). METHODS From May 1, 2005, through November 10, 2005, 17 healthy volunteers (17 eyes) had raster scans (180 frames, 501 samplings per frame) centered on the optic disc taken with stereo-optic DP and high-speed ultrahigh-resolution OCT (hsUHR-OCT). T...

Magnetic resonance images (MRIs) were obtained of 52 temporomandibular joints (TMJs) of 30 patients with TMJ disease, before insertion of an anterior repositioning splint. Ten TMJs showed a normal disc-condyle relationship. Pathological findings were partial or complete anterior disc displacement with disc reduction (n = 18), without (n = 7), or with partial reduction (n = 4) or non-reducing jo...
