Background: The involvement of human subjects in the development of biomedical devices presents both ethical and practical challenges. Electroencephalography (EEG) signals exhibit interindividual variability and are subject to fluctuations induced by movement and emotional states. Hence, the fabrication of artificial…

We demonstrate a novel femtosecond-scale optical gating technique based on non-degenerate two-photon absorption (2PA) directly within the photodetector, thereby integrating nonlinear gating and signal detection into a single element. This method eliminates the need for separate nonlinear crystals and complex optical a…

The performance of ultrasound technologies, including biomedical imaging, therapeutics, and industrial inspection, is fundamentally dependent on the efficient transmission of acoustic energy between the transducer and the target medium. This is conventionally achieved through the use of acoustic couplants. Traditional…

BACKGROUND: Early detection of increased intracranial pressure (ICP) is critical in managing acute ischemic cerebrovascular disease (CVD) to prevent secondary brain injury. Optic nerve sheath diameter (ONSD) has emerged as a promising non-invasive surrogate marker for monitoring ICP changes. OBJECTIVE: This study aime…

Background: Repeated radiographic monitoring exposes scoliosis patients to cumulative radiation. Dynamic infrared thermography (DIT) may provide a non-invasive alternative by characterizing thermal recovery behavior following controlled cooling. This study investigated whether reheating-based thermographic analysis co…

Abstract Objective Robotic-assisted needle insertions lack haptic feedback, a key sensory cue for detecting tissue transitions and regulating puncture force. Modeling this feedback requires an understanding of soft-tissue biomechanics during insertion. Vibroacoustic signals generated by needle–tissue interactions may…

Abstract Treatment of solid tumors remains one of the biggest challenges in oncology. Targeted nanotherapeutics could significantly improve treatment efficacy and reduce side effects. However, their efficient implementation requires knowledge of pharmacokinetics (PK) and biodistribution (BD) during therapy administrat…

This repository contains MATLAB 2022b code for automated AS-OCT-based image processing of anterior chamber inflammation. The function file provides the main modular analysis pipeline for reproducible numerical output, while the Live Editor file contains the same computational workflow with additional visualization and…
