Summary
A new strip-scanning method enhances optical coherence tomography angiography (OCTA) mosaicking efficiency. This technique improves visualization of retinal capillaries across wide fields-of-view for disease detection.
Area of Science:
- Ophthalmic imaging
- Medical diagnostics
- Biomedical engineering
Background:
- Optical coherence tomography angiography (OCTA) is crucial for visualizing retinal vasculature.
- Current OCTA methods face challenges in achieving efficient widefield imaging and capillary resolution.
Purpose of the Study:
- To introduce a novel strip-scanning method for OCTA.
- To demonstrate its utility in efficient widefield OCTA mosaicking.
Main Methods:
- Derivation of an analytical expression for strip-scanned OCTA mosaicking efficiency.
- Utilizing strip-scanned OCTA with simultaneous retinal tracking for motion-corrected mosaicking.
- Achieving capillary resolution in multi-volume OCTA mosaicking.
Main Results:
- Strip-scanning asymptotically achieves a two-fold gain in mosaicking efficiency.
- Workload for OCTA mosaicking is reduced as field-of-view increases.
- Demonstrated motion-corrected widefield retinal OCTA mosaicking (35° × 45°) at capillary resolution.
Conclusions:
- Strip-scanned OCTA significantly improves widefield OCTA mosaicking efficiency.
- This method aids in the detection and monitoring of retinal vascular diseases by enhancing capillary visualization.

01:13Voltammetry: Stripping Methods
986
Anodic Stripping Voltammetry (ASV), Cathodic Stripping Voltammetry (CSV), and Adsorptive Stripping Voltammetry (AdSV) are electrochemical techniques used to determine trace amounts of analytes in solution. These methods involve applying a potential to an electrode and measuring the resulting current.
Anodic Stripping Voltammetry (ASV)
ASV is used to determine metals and metalloids at trace levels. It involves two steps: deposition and stripping. First, a negative potential is applied to the...

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

5.6K
A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

01:01Production Efficiency
18.4K
Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

00:46Trophic Efficiency
25.2K
Trophic level transfer efficiency (TLTE) is a measure of the total energy transfer from one trophic level to the next. Due to extensive energy loss as metabolic heat, an average of only 10% of the original energy obtained is passed on to the next level. This pattern of energy loss severely limits the possible number of trophic levels in a food chain.

01:16Efficiency of The Carnot Cycle
3.7K
The hypothetical Carnot cycle consists of an ideal gas subjected to two isothermal and two adiabatic processes. Since the internal energy of an ideal gas depends only on its temperature, which is the same before and after the completion of the Carnot cycle, there is no change in its internal energy. Hence, using the first law of thermodynamics, the total heat exchanged by the ideal gas equals the total work done. Thus, we can quantify the efficiency of the Carnot cycle via the heat exchanged...
