Using Automatic Exposure Control in Digital Radiography

computed radiographs of the chest in pediatric patients, Med. Phys. 199:242-252, 1996. Use of a rating system based on degrees of mottle to determine what sensitivity number of a Fuji AC series would be needed to match the mottle in a 600-speed s/f system, then use the actual sensitivity numbers measured to compare CR to s/f.

PET/CT Acceptance Testing and Quality Assurance

tance testing or follow-up measurements can be validated against established benchmarks. This document provides guidance on acceptance testing and quality control (QC) of the PET sub-system of any commercial PET/CT scanner and can be used to enable direct comparisons among vari-ous scanner models and manufacturers.

Abstract

High Resolution Classifier. All state-of-the-art detec-tion methods use classifier pre-trained on ImageNet [16]. Starting with AlexNet most classifiers operate on input im-ages smaller than 256 256 [8]. The original YOLO trains the classifier network at 224 224 and increases the reso-lution to 448 for detection. This means the network has to

high-resolution natural images. Unsupervisedrepresentation learning can also be formu-lated as learning an embedding (i.e. a feature vector for each image) where images that are semantically similar are close, while semantically different ones are far apart. One way to build such a representation is to create a supervised

the spatial and temporal attributes. Only two geographic features were included, the X and Y axis values where the fire occurred, since the type of vegetat ion presented a low quality (i.e. more than 80% of the values were missing). After consulting the Mon-tesinho fire inspector, we selected the month and day of the week temporal variables.
