Deep-Learning-Driven High Spatial Resolution Attenuation Imaging for Ultrasound Tomography (AI-UT).

IEEE transactions on ultrasonics, ferroelectrics, and frequency control
Ultrasonic attenuation can be used to characterize tissue properties of the human breast. Both quantitative ultrasound (QUS) and ultrasound tomography (USCT) can provide attenuation estimation. However, limitations have been identified for both appro...

Development of an anomaly detection system for Gibbs artifact identification in amyloid PET imaging.

Radiological physics and technology
The PET Imaging Site Qualification Program for amyloid positron emission tomography (PET) in Japan includes visual evaluation of the cylinder phantom. This visual evaluation requires observation of the entire image of the phantom and confirmation of ...

Denoising of high-resolution 3D UTE-MR angiogram data using lightweight and efficient convolutional neural networks.

Magnetic resonance imaging
High-resolution magnetic resonance angiography (∼ 50 μm MRA) data plays a critical role in the accurate diagnosis of various vascular disorders. However, it is very challenging to acquire, and it is susceptible to artifacts and noise which limits its...

Groupwise image registration with edge-based loss for low-SNR cardiac MRI.

Magnetic resonance in medicine
PURPOSE: The purpose of this study is to perform image registration and averaging of multiple free-breathing single-shot cardiac images, where the individual images may have a low signal-to-noise ratio (SNR).

Hybrid Magnetic Locomotion Method for Capsule Robots.

IEEE transactions on bio-medical engineering
OBJECTIVE: Gastrointestinal (GI) capsule endoscopes typically rely on a single mode of locomotion, which limits their efficiency within the complex GI tract. To address this issue, this paper presents a hybrid magnetic locomotion method for capsule r...

Evaluation of a Low-Cost Amplifier With System Optimization in Thermoacoustic Tomography: Characterization and Imaging of Ex-Vivo and In-Vivo Samples.

IEEE transactions on bio-medical engineering
Microwave-induced thermoacoustic tomography (TAT) is a hybrid imaging technique that combines microwave excitation with ultrasound detection to create detailed images of biological tissue. Most TAT systems require a costly amplification system (or a ...

Design of Magnetic Actuated Capsule Robot for Liquid Sampling.

IEEE transactions on bio-medical engineering
OBJECTIVE: This study aims to introduce a biopsy capsule robot based on the negative pressure suction principle to achieve liquid sampling in the digestive tract.

Novel Design of a Surgical Tool Insertion Robot Using a Chebyshev Lambda Mechanism.

The international journal of medical robotics + computer assisted surgery : MRCAS
BACKGROUND: Endoscopic Retrograde Cholangiopancreatography (ERCP) and Percutaneous Coronary Intervention (PCI) are minimally invasive procedures that treat diseases with minimal scarring and rapid recovery. However, catheterisation under fluoroscopy ...

Bedside Ultrasound Vector Doppler Imaging System With GPU Processing and Deep Learning.

IEEE transactions on ultrasonics, ferroelectrics, and frequency control
Recent innovations in vector flow imaging promise to bring the modality closer to clinical application and allow for more comprehensive, high frame-rate vascular assessments. One such innovation is plane-wave multi-angle vector Doppler, where pulsed ...

Self-Supervised Optimization of RF Data Coherence for Improving Breast Reflection UCT Reconstruction.

IEEE transactions on ultrasonics, ferroelectrics, and frequency control
The reflection ultrasound computed tomography (UCT) is gaining prominence as an essential instrument for breast cancer screening. However, reflection UCT quality is often compromised by the variability in sound speed across breast tissue. Traditional...
