An automated method for measurement of arteriolar-to-venular diameter ratio (AVR) is presented. The method includes optic disc segmentation for the determination of the AVR measurement zone, retinal vessel segmentation, vessel classification into arteries and veins, selection of major vessel pairs, and measurement of AVRs. The sensitivity for the major vessels in the measurement zone was 87%, w...

BACKGROUND Hepatocellular carcinoma is a primary tumor of the liver and involves different treatment modalities according to the tumor stage. After local therapies, the tumor evaluation is based on the mRECIST criteria, which involves the measurement of the maximum diameter of the viable lesion. This paper describes a computed methodology to measure through the contrasted area of the lesions th...

ABSTRACT Introduction Using ultrasound to measure optic nerve sheath diameter (ONSD) has been shown be a useful modality detect elevated intracranial pressure. However, manual assessment of ONSD by human operator is cumbersome and prone errors. We aimed develop test an automated algorithm for measurement using images compare it measurements performed physicians. Materials Methods Patients were ...
