Biophotonics in veterinary medicine: the first steps toward clinical translation
Cugmas, Blaž; Spīgulis, Jānis (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 ... -
Challenges in automated estimation of capillary refill time in dogs
Cugmas, Blaž; Spīgulis, Jānis (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 ... -
Clinical evaluation of automated capillary refill time estimation in dogs and cats
Cugmas, Blaž; Štruc, Eva; Spīgulis, Jānis (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 ... -
Photoplethysmography in dogs and cats: a selection of alternative measurement sites for a pet monitor
Cugmas, Blaž; Štruc, Eva; Spīgulis, Jānis (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 ... -
Skimager for the objective erythema estimation in atopic dogs
Cugmas, Blaž; Olivry, Thierry; Olivrī, Alla; Spīgulis, Jānis (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 ...
