Optical imaging techniques, such as laser speckle imaging, offer a non-invasive, cost-effective, and scalable approach to monitoring cerebral blood flow and volume with high temporal resolution. These ...

We propose a novel single-shot wide-field imaging method that maps local temporal intensity decorrelations of dynamic speckle fields. Our method, named rolling shutter speckle imaging (RSSI), utilizes ...

A new technical paper titled “Controlling Speckle Contrast Using Existing Lithographic Scanner Knobs to Explore the Impact on ...

Trapped immune cells laden with microplastics starve the brain of oxygen—mouse study links vascular blockages to memory loss ...

Studies in mice show that microplastics entering the bloodstream are engulfed by immune cells, forming clusters that can ...

Abstract: Ultrafast plane-wave ultrasound imaging is a versatile tool which has become increasingly relevant for blood flow imaging using speckle tracking, but suffers from a low signal-to-noise ratio ...

The Accuvix V20's ultrasound imaging system represents the pinnacle ... enhances border detection and contrast resolution while decreasing speckle echoes. DMR+™ is particularly helpful when ...

Transfusions of red blood cells (RBCs) can be life-saving treatments for patients suffering from anemia, where the body lacks enough healthy RBCs to effectively deliver oxygen around the body. But the ...

We aimed to evaluate LV function using two-dimensional (2D) and three-dimensional (3D) speckle-tracking echocardiography in patients with HFpEF with and without T2D, and to investigate its prognostic ...

Jan. 14, 2025 — Using advanced imaging techniques and precise microfluidics control to stretch out curly DNA into a straight line, new research demonstrates techniques for stretching and ...
