Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

Advanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots

Advanced Robotics Research, EarlyView.
Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...

Multislice spiral computed tomography angiography of mesenteric arteries

The Lancet, 2001
The introduction of multislice technology has improved and expanded the clinical applications of computed tomography angiography (CTA), and it is now possible to detect subtle vascular abnormalities. We optimised a high resolution CTA protocol to study the anatomy of mesenteric arteries with a multislice spiral CT scanner. We showed that multislice CTA

Spiral computed tomography for pulmonary embolism

Hospital Medicine, 2000
Spiral computed tomography pulmonary angiography is increasingly used in the non-invasive investigation of patients with suspected pulmonary embolism. This review will focus on current techniques and indications with an explanation of the computed tomography signs of pulmonary embolism, possible pitfalls in interpretation and limitations of the ...

Spiral computed tomography for staghorn calculi

Urology, 1997
To assess the utility of spiral computed tomography (CT) with three-dimensional reconstruction for preoperative planning of percutaneous nephrostolithotomy in patients with complex branched calculi (full staghorns).Patients with complex branched stones were imaged with spiral CT with three-dimensional reconstruction.

Spiral computed tomography for biliary dilatation

Journal of Pediatric Surgery, 1995
Spiral computed tomography (SCT), which consists of rapid volumetric data acquisition and planar image display, was performed on 12 patients with biliary dilatation after excisional procedure. The technique was evaluated for image quality and impact on clinical practice. All patients safely underwent SCT scanning after intravenous cholangiography (IVC)

Optimal pitch in spiral computed tomography

Medical Physics, 1997
The focus of this paper is to analytically optimize spiral/helical computed tomography (CT) protocols based on a simplified imaging model. Spiral CT was approximately modeled as follows: Using the half‐scan raw data interpolation method, the variance of the spiral CT slice sensitivity profile is equal to the sum of squared detector collimation divided ...

Spiral Computed Tomography

2017
X-ray computed tomography (CT) is a medical imaging method, where the patient is placed on the CT table and an x-ray tube rotates around the body and sends x-rays through the body. Those x-rays experience a varying attenuation along their way depending on the body part they are transversing.

Predicting Postoperative FEV1 Using Spiral Computed Tomography

Academic Radiology, 2010
Lung resection for primary bronchogenic carcinoma in the setting of chronic obstructive pulmonary disease often requires a detailed assessment of lung function to avoid perioperative complications and long-term disability. The aim of this study was to test the hypothesis that a novel technique of spiral computed tomographic (CT) subtraction imaging ...

Spiral computed tomography for bilioenteric anastomotic stricture

Pediatric Surgery International, 1998
Spiral computed tomography scanning after intravenous cholangiography (IVC-SCT) was used to assess the anatomy of the biliary tree and anastomosis in a 7-year-old girl with recurrent cholangitis 5 years after surgical excision of a choledochal cyst.
