Visualization of Distal Vessels during Mechanical Thrombectomy using Aortic Cone-beam Computed Tomography

Neurologia Medico-Chirurgica
During mechanical thrombectomy, manipulation under the limited visibility of vessels distal to the occlusion site could result in vessel perforation. Standard imaging techniques such as magnetic resonance imaging and digital subtraction angiography often

Appropriate indications for computed tomography coronary angiography [PDF]

Medical Journal of Australia, 2012
Computed tomography coronary angiography (CTCA) has been shown in multicentre trials to be reliable in ruling out significant coronary artery disease (CAD). It is used most appropriately in symptomatic patients with low to intermediate pretest probability of CAD.

Microendovascular Neural Recording from Cortical and Deep Vessels with High Precision and Minimal Invasiveness

Advanced Intelligent Systems, EarlyView.
Intravascular electroencephalography (ivEEG) using micro‐intravascular electrodes was developed. Cortical‐vein ivEEG showed a higher signal‐to‐noise ratio and finer spatial resolution of somatosensory evoked potentials (SEPs) than superior sagittal sinus ivEEG, and deep‐vein ivEEG captured clear visual evoked potentials.

Contact Force Estimation of Continuum Robots without Embedded Sensors: A Review

Advanced Intelligent Systems, EarlyView.
This review surveys methods for estimating contact forces in continuum robots without embedded sensors. It explains why contact force matters, classifies force patterns, and groups existing methods into three approaches based on actuation, deformation, and environment information.
