Super-resolution photoacoustic imaging via flow induced absorption fluctuations

, 2017
In deep tissue photoacoustic imaging the spatial resolution is inherently limited by the acoustic wavelength. We present an approach for surpassing the acoustic diffraction limit by exploiting temporal fluctuations in the sample absorption distribution ...

Standardized Management Pathway to Prevent Acute Rejection After Liver Transplantation Following ICI Therapy for Downstaging HCC

Health Care Science, EarlyView.
Findings indicate that within a standardized clinical pathway integrating structured immunosuppression, therapeutic drug monitoring, and early complication surveillance, liver transplantation after ICI exposure can be performed safely without increased rejection risk.

Development and External Validation of an Efficient Deep Learning Model for Lesion Segmentation and Subtyping of Hepatic Echinococcosis in Ultrasound Imaging

Health Care Science, EarlyView.
We developed a lightweight deep learning framework that integrates frequency‐ and spatial‐domain ultrasound features with segmentation‐assisted classification for hepatic echinococcosis diagnosis. The model outperformed existing state‐of‐the‐art methods in both accuracy and inference speed while requiring substantially fewer computational resources ...

Anatomical Variation of Absent Facial Vein: Implications for Facial Reanimation Surgery

Head &Neck, EarlyView.
ABSTRACT Background The facial vein is the standard recipient vessel in facial reanimation surgery. Its complete absence is rarely described but may cause major challenges during free functional muscle transfer (FFMT). This study aimed to determine the prevalence and predictors of facial vein absence and assess its surgical relevance in facial ...

Research progress on the use of the optical coherence tomography system for the diagnosis and treatment of central nervous system tumors

Ibrain, Volume 11, Issue 1, Page 3-18, Spring 2025.
With the advantages of high‐resolution imaging, efficient image acquisition, intraoperative real‐time detection, and radiation‐free and noninvasive characteristics, optical coherence tomography (OCT) provides accurate diagnosis and effective intraoperative guidance for the minimally invasive diagnosis and treatment of central nervous system (CNS ...

Obstetrics and gynecology devices designed for low‐ and middle‐income countries: A narrative review

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 71-80, April 2025.
Abstract There are many barriers contributing to poor health outcomes for women in low‐ and middle‐income countries (LMICs), one of which is the lack of necessary medical devices. Presently, the development of various kinds of devices intended to improve women's health outcomes specifically in LMICs remains underrepresented in the literature; therefore,
