What is Spectralis?
The SPECTRALIS® is an ophthalmic imaging platform with an upgradable, modular design. Multimodal imaging options include: OCT, multiple scanning laser fundus imaging modalities, widefield and ultra-widefield, scanning laser angiography and OCT angiography.
What imaging system does Spectralis use?
The SPECTRALIS® is an expandable diagnostic imaging platform which combines scanning laser fundus imaging with high-resolution OCT.
How do I turn on Heidelberg?
The power switch is located on the front panel of the power supply. The ‘On’ position is marked I. (3) Start the Heidelberg Eye Explorer software. or by using the windows start menu: Start → Programs → Heidelberg Eye Explorer → Heidelberg Eye Explorer Wait until the software opens to the database view.
How does OCTA work?
OCTA works by detection of erythrocyte motion, so any extraneous movement during the image-capturing process may result in motion artifacts, which appear as white or black lines in the flow angiograms, and/or misalignment of the retinal vasculature.
What is eye Oct?
Optical Coherence Tomography (OCT) is a non-invasive diagnostic instrument used for imaging the retina. The OCT uses an array of light to rapidly scan the eye. These scans are interpreted and the OCT then presents an image of the tissue layers within the retina.
How does Heidelberg retinal tomography work?
The HRT uses a special laser to take 3-dimensional photographs of the optic nerve and surrounding retina. This laser, which will not harm the eye, is focused on the surface of the optic nerve and captures the image. The HRT takes images of deeper and deeper layers until the desired depth has been reached.
How do you work an OCT machine?
A standard polymerase chain reaction (PCR) setup consists of four steps:
- Add required reagents or mastermix and template to PCR tubes.
- Mix and centrifuge.
- Amplify per thermo cycler and primer parameters.
- Evaluate amplified DNA by agarose gel electrophoresis followed by ethidium bromide staining.
What does an OCTA measure?
OCTA uses low-coherence interferometry to measure changes in backscattered signal to differentiate areas of blood flow from areas of static tissue. …
What is the purpose of the Heidelberg SPECTRALIS HRA-Oct?
Designed for angiographies, the SPECTRALIS HRA-OCT is built on a Confocal Scanning Laser Ophthalmoscopy (cSLO) platform that is exceptionally sensitive to the fluorescence of Fluoresceine or ICG dyes. This provides focused and high contrast imaging either as still images or Heidelberg’s unique high speed imaging (movies).
Which is part of the SPECTRALIS OCT imaging platform?
The SPECTRALIS ® OCT imaging platform combines scanning laser fundus imaging with simultaneously acquired OCT. As an expandable platform, it can be upgraded with additional scanning laser fundus imaging modalities, such as BluePeak autofluorescence and MultiColor, as well as advanced modules such as OCT2 and the Glaucoma Module Premium Edition.
What kind of image is produced by SPECTRALIS?
1.2.2 Optical Coherence Tomography (OCT) The Spectralis OCT and the Spectralis HRA+ tomography (SD-OCT) technology, also referred to as Fourier domain OCT (FD- OCT). The beam of a super luminescence diode (SLD) scans across the retina to produce a cross sectional B-scan image.
How are multimodal imaging modalities used in SPECTRALIS?
This platform allows clinicians to configure each SPECTRALIS to the specific diagnostic workflow in the practice or clinic. Multimodal imaging options include: OCT, multiple scanning laser fundus imaging modalities, widefield and ultra-widefield, scanning laser angiography and OCT angiography.
