Challenges in automated estimation of capillary refill time in dogs
Capillary refill time (CRT) is a part of the cardiorespiratory examination in dogs. Changes in CRT can reflect pathological conditions like shock or anemia. Visual CRT estimation has low repeatability; therefore, optical ...
Color constancy in dermatoscopy with smartphone
The recent spread of cheap dermatoscopes for smartphones can empower patients to acquire images of skin lesions on their own and send them to dermatologists. Since images are acquired by different smartphone cameras under ...
Biophotonics in veterinary medicine: the first steps toward clinical translation
In this paper, we analyzed the current situation and the potential of biophotonics and biomedical optics in veterinary medicine. Promising optical techniques such as optical coherence tomography, pulse oximeter, and ...
Photoplethysmography in dogs and cats: a selection of alternative measurement sites for a pet monitor
(IOP Publishing, 2019-01-22)
Objective: Photoplethysmography (PPG) is an increasingly popular health and well-being tool for monitoring heart rate and oxygen saturation. Due to the pigmentation and hairiness of dogs and cats, a pulse oximeter is ...
Poor optical stability of molecular dyes when used as absorbers in water-based tissue-simulating phantoms
Biomedical optical systems and models can be easily validated by the use of tissue-simulating phantoms. They can consist of water-based turbid media which often include inks (India ink and molecular dyes) as absorbers. ...
Clinical evaluation of automated capillary refill time estimation in dogs and cats
In this study, we clinically evaluated a pulse oximeter-based device for automated capillary refill time (CRT) estimation in dogs and cats. CRT can reveal conditions like shock or anemia in dogs and cats. However, visual ...
