Skimager for the objective erythema estimation in atopic dogs
(International Society for Optics and Photonics (SPIE), 2020-02-19)In this study, the severity of canine skin erythema was assessed objectively for the first time. Atopic dermatitis (AD) is a common canine inflammatory and pruritic skin disease associated with an allergic reaction to ... -
Photoplethysmography for bovine heat detection: the preliminary results
(International Society for Optics and Photonics (SPIE), 2020-02-14)In this study, we applied photoplethysmography (PPG) as an alternative, convenient, and affordable method for bovine heat detection. Heat detection is an essential part of effective herd reproduction management. Currently, ... -
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
(SPIE, 2019-02-27)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. ... -
Biophotonics in veterinary medicine: the first steps toward clinical translation
(SPIE, 2019-02-20)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 ... -
Clinical evaluation of automated capillary refill time estimation in dogs and cats
(SPIE, 2019-02-26)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 ... -
Color constancy in dermatoscopy with smartphone
(SPIE, 2017-12-07)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 ... -
Challenges in automated estimation of capillary refill time in dogs
(SPIE, 2018-02-20)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 ...
