Multimodal Feature Fusion and Knowledge-Driven Learning via Experts Consult for Thyroid Nodule Classification [PDF]

open access: yes, 2020
Computer-aided diagnosis (CAD) is becoming a prominent approach to assist clinicians spanning across multiple fields. These automated systems take advantage of various computer vision (CV) procedures, as well as artificial intelligence (AI) techniques, to formulate a diagnosis of a given image, e.g., computed tomography and ultrasound. Advances in both

Interventional endoscopic ultrasonography for pancreatic cancer

open access: yesWorld Journal of Clinical Oncology, 2011
Endoscopic ultrasonography (EUS) represents the combination of endoscopy and intraluminal ultrasonography. This allows use of a high-frequency transducer (5-20 MHz) that, due to the short distance to the target lesion, provides ultrasonographic images of higher resolution than those obtained from other imaging modalities, including multiple-detector ...

Current Advances in Computational Lung Ultrasound Imaging: A Review [PDF]

open access: yesarXiv, 2021
In the field of biomedical imaging, ultrasonography has become increasingly widespread, and an important auxiliary diagnostic tool with unique advantages, such as being non-ionising and often portable. This article reviews the state-of-the-art in medical ultrasound image computing and in particular its application in the examination of the lungs. First,

Radial artery duplication: Unusual point-of-care-ultrasonography finding during arterial cannulation

open access: yesSaudi Journal of Anaesthesia, 2023
The radial artery is the most common choice for arterial cannulation, coronary interventions, and various interventional radiological procedures. Here, we describe a case of unilateral duplication of the radial artery detected during radial artery ...

An ultrasonography-based approach for optical diagnostics and phototherapy treatment strategies [PDF]

open access: yesarXiv, 2022
Currently, diagnostic medicine uses a multitude of tools ranging from ionising radiation to histology analysis. With advances in piezoelectric crystal technology, high-frequency ultrasound imaging has developed to achieve comparatively high resolution without the drawbacks of ionising radiation.

Efficient asymmetric transmission of elastic waves in thin plates with lossless metasurfaces [PDF]

open access: yesPhys. Rev. Applied 14, 054029 (2020), 2020
Requiring neither active components nor complex designs, we propose and experimentally demonstrate a generic framework for undistorted asymmetric elastic-wave transmission in a thin plate just using a layer of lossless metasurface. The asymmetric transmission stems from the uneven diffraction of +1 and -1 orders on opposite sides of the metasurface ...
