Advances in Procedural Echocardiographic Imaging in Transcatheter Edge-to-Edge Repair for Mitral Regurgitation

open access: yesFrontiers in Cardiovascular Medicine, 2022
Transcatheter edge-to-edge repair (TEER) therapy is recommended by the American College of Cardiology/American Heart Association (ACC/AHA) guidelines for selected patients with symptomatic severe or moderate-severe mitral regurgitation (MR ...

CONSERVATION MONITORING OF A HERITAGE CEILING BY PHOTOMETRIC STEREO [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Photographic survey techniques were employed to monitor the condition of the paintwork on the ceiling of the Queen's Staircase at Hampton Court Palace. Illumination was provided by a flash, mounted on an 8 metre telescopic mast, raised to approximately ...

3D infrared thermospectroscopic imaging [PDF]

open access: yesScientific Reports, 2020
AbstractThis work reports a multispectral tomography technique in transmission mode (called 3DITI for 3D Infrared Thermospectroscopic Imaging) based on a middle wavelength infrared (MWIR) focal plane array. This technique relies on an MWIR camera (1.5 to 5.5 μm) used in combination with a multispectral IR monochromator (400 nm to 20 μm), and a sample ...

Sharp-wave ripple doublets induce complex dendritic spikes in parvalbumin interneurons in vivo

open access: yesNature Communications, 2022
The influence of sharp-wave ripples (SPW-Rs) on dendritic computation remains poorly understood. Here, the authors demonstrate the existence of SPW-R associated, branch-specific, dendritic spikes which serve as a temporal and spatial coincidence ...

3D imaging scanner

open access: yesApplied Optics, 2018
This paper proposes a multi-view three-dimensional display method based on a scanning imaging system with the light-intensity characteristic recorded by an improved flatbed scanner. Within the effective scanning depth of the imaging sensor, two transmission images are each simultaneously acquired by two linear CCD modules with different focal planes ...

The utility of three-dimensional models in complex microsurgical reconstruction

open access: yesArchives of Plastic Surgery, 2020
Background Three-dimensional (3D) model printing improves visualization of anatomical structures in space compared to two-dimensional (2D) data and creates an exact model of the surgical site that can be used for reference during surgery.

Axial plane optical microscopy. [PDF]

open access: yes, 2014
We present axial plane optical microscopy (APOM) that can, in contrast to conventional microscopy, directly image a sample's cross-section parallel to the optical axis of an objective lens without scanning.

The effectiveness of the use of augmented reality in anatomy education: a systematic review and meta-analysis

open access: yesScientific Reports, 2021
The use of Augmented Reality (AR) in anatomical education has been promoted by numerous authors. Next to financial and ethical advantages, AR has been described to decrease cognitive load while increasing student motivation and engagement.

Deformation Detection of Mining Tunnel Based on Automatic Target Recognition

open access: yesRemote Sensing, 2023
Mining tunnels have irregular and diverse cross-sectional shapes. Structural deformation detection using mobile laser measurement has some problems, such as the inconvenient positioning of the deformation, difficulties in unifying the multiphase data ...
