Body-Mounted Robotic System for MRI-Guided Shoulder Arthrography: Cadaver and Clinical Workflow Studies.

This paper presents an intraoperative MRI-guided, patient-mounted robotic system for shoulder arthrography procedures in pediatric patients. The robot is designed to be compact and lightweight and is constructed with nonmagnetic materials for MRI safety. Our goal is to transform the current two-step arthrography procedure (CT/x-ray-guided needle insertion followed by diagnostic MRI) into a streamlined single-step ionizing radiation-free procedure under MRI guidance.

Acoustic characterization of Thiel liver for magnetic resonance-guided focused ultrasound treatment.

Background: The purpose of this work was to measure the essential acoustic parameters, i.e., acoustic impedance, reflection coefficient, attenuation coefficient, of Thiel embalmed human and animal liver.

Quantitative assessment of Thiel soft-embalmed human cadavers using shear wave elastography.

Introduction: Thiel soft-embalmed human cadavers are increasingly being used as a model to train surgeons and anesthetists because they look and feel like patients. However, there is a need to validate quantitatively the tissue properties of this model. Thus, the main objective of this study was to measure the elasticity of tissue in the Thiel soft-embalmed cadaver, using results in the literature for human volunteers for comparison.
