High-Resolution ADCs Design in Image Sensors [PDF]

open access: yes, 2018
This paper presents design considerations for high-resolution and high-linearity ADCs for biomedical imaging ap-plications. The work discusses how to improve dynamic spec-ifications such as Spurious Free Dynamic Range (SFDR) and Signal-to-Noise-and ...

ImageBox 2 – Efficient and rapid access of image tiles from whole-slide images using serverless HTTP range requests

open access: yesJournal of Pathology Informatics, 2020
Background: Whole-slide images (WSI) are produced by a high-resolution scanning of pathology glass slides. There are a large number of whole-slide imaging scanners, and the resulting images are frequently larger than 100,000 × 100,000 pixels which ...

Lateral and axial resolution criteria in incoherent and coherent optics and holography, near- and far-field regimes [PDF]

open access: yes, 2019
This work presents an overview of the spatial resolution criteria in classical optics, digital optics and holography. Although the classical Abbe and Rayleigh resolution criteria have been thoroughly discussed in the literature, there are still several ...

Digital detection of biomarkers for low-cost, high-sensitivity diagnostics [PDF]

open access: yes, 2016
We have demonstrated Interferometric Reflectance Imaging Sensor (IRIS) with the ability to detect single nanoscale particles. By extending single-particle IRIS to in-liquid dynamic imaging, we demonstrated real-time digital detection of individual viral ...

Assessing Cognitive Functioning in Children With Brain Tumors: Interaction of Neighborhood Social Determinants of Health and Neurological Risk

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background This study investigated how neighborhood‐level social determinants of health (SDOH), including redlining and neurological risk, interact to influence cognitive outcomes in children treated for brain tumors (CTBT). Methods A retrospective chart review of 161 CTBT aged 5–17 was conducted.

Small Target Radiometric Performance of Drone-Based Hyperspectral Imaging Systems

open access: yesRemote Sensing
Hyperspectral imaging systems frequently rely on spectral rather than spatial resolving power for identifying objects within a scene. A hyperspectral imaging system’s response to point targets under flight conditions provides a novel technique for ...

Guided classification measurement of body condition in beef cows

open access: yesAgrociencia Uruguay, 2023
The use of predictive techniques based on image acquisition at field level is presented to improve livestock production. With this, the farmer can plan the management of the herd and the need for supplemental feeding. The use of the Body Condition Score (
