The shoulder joint complex is prone to musculoskeletal issues, such as rotator cuff-related pain, which affect two-thirds of adults and often result in suboptimal treatment outcomes. Current musculoskeletal models used to understand shoulder biomechanics are limited by challenges in personalization, inaccuracies in predicting joint and muscle loads, and an inability to simulate anatomically accurate motions. To address these deficiencies, we developed a novel, personalized modeling framework capable of calibrating subject-specific joint centers and functional axes for the shoulder complex.

This study aimed to validate the use of weightbearing computed tomography against conventional computed tomography and against bead tracking for markerless tracking of key foot and ankle bones. A left cadaveric limb was implanted with tantalum beads and underwent conventional computed tomography and weightbearing computed tomography scanning, followed by biplane fluoroscopy motion capture to simulate gait. Bone models from conventional computed tomography and weightbearing computed tomography were compared for surface differences and kinematic analysis across six joints.

Purpose: To investigate the feasibility of evaluating the functionality of x-ray angiography systems based on detailed exposure data extracted from DICOM radiation dose structured reports (RDSR).
Methods: Structured reports provide information about each x-ray irradiation event (a fluoroscopy or acquisition series) part of a clinical procedure. This data was utilized to evaluate the functionality of angiography systems installed in three pediatric and adult cardiology suites, one abdominal radiology suite, and two neurology suites.

Ventricular arrhythmias after myocardial infarction (MI) originate from discrete areas within the MI border zone (BZ), identified during functional electrophysiology tests. Accurate sampling of arrhythmogenic sites for ex-vivo study remains challenging, yet is critical to identify their tissue, cellular and molecular signature. In this study, we developed, validated, and applied a targeted sampling methodology based on individualized 3D prints of the human-sized pig heart.

Background: The choice of angiography system could influence the outcomes of mechanical thrombectomy (MT) in the treatment of acute ischemic stroke (AIS), but its impact is not yet well understood. This study aims to compare the clinical and technical outcomes of MT performed with single plane versus biplane angiography systems.
Method: We conducted a systematic review and meta-analysis, following PRISMA guidelines, by searching PubMed, Embase, Web of Science, and Scopus to include studies on patients with AIS who underwent MT with either single plane or biplane angiography up to May 4, 2024.
