CONT

Techniques of recording. The pupils are well dilated and the patient sits in front of the camera with one arm outstretched. Twenty-five milligrams of ICG [indocyanine green] dye is dissolved in 0.5 ml [millilitres] of the manufacturers aqueous solvent and given intravenously as a bolus followed by a 5 ml physiological saline solution flush. The flush eliminates the need for image intensification. Preferably 10 images should be obtained starting immediately after injection and lasting the first 30 seconds. ... The ICG angiograms may be recorded either by using a modified conventional fundus camera or scanning laser ophthalmoscope.

angiogram : An x-ray or computer image... of the blood vessels and blood flow in the body.

CONT

Optical coherence tomography angiography(OCTA) is a noninvasive technique that can detect blood flow signal in retinal and choroidal vessels using motion contrast. It compares the decorrelation signal(differences in the backscattered OCT [optical coherence tomography] signal intensity) between sequential OCT B-scans taken at the same cross-section; thus, yielding maps of vascular flow.... Numerous studies described how to automatically detect and classify retinal disorders(e. g., diabetic retinopathy [DR]). However, most of them relied on fundus images rather than on OCT images or OCT angiograms. Recent development in OCTA induced attempts to use advanced image processing in order to extract quantitative information that characterizes the vascular network in the retina from the angiograms.

  • Vessels (Medicine)
  • The Eye
CONT

Angiograms are taken after the injection of a dye in the patient’s arm to enhance the appearance of blood vessels, under a specific illumination and filter. The dye has an absorption peak, which determines the illumination light, and an emission peak, which determines the filter that retains only the fluorescent contribution. ... Images are acquired from 10 [seconds] to 15 [minutes] after the injection while the dye circulates through the retinal arteries, capillaries, veins, and is eliminated from the vasculature, while staining in the optic disc and lesions. ... Fluorescein angiograms ... are useful in detecting leaks and other abnormalities in arteries and veins. They allow the detection of occluded and leaking capillaries, microaneurisms, macular edema, and neovascularization.

  • Vulcanology and Seismology

DEF

... a proven technology for acquiring empirical data on the dimensions of created fracture systems.

CONT

The production of hydrocarbon reservoirs, the exploitation of hydrothermal fields and mining activity in general are associated with microseismicity. Changes of the local stress fields and pore pressure can initiate sudden movements along existing faults or can generate new fractures which in turn result in the emission of seismic energy. Monitoring and analyses of microseismic events have the potential to delineate the internal structure of the subsurface, to obtain information on the present stress conditions and to image dynamic processes like subsidence and fluid flow.

[A] technology [which] provides for the direct transfer of the image from digital files to the image carrier (plate) of the press.

OBS

A direct imaging press is basically a conventional offset press except that the image carrier(plate) is imaged directly on the press with built-in laser exposure units. Many of the press settings, such as plate registration, ink flow, and cleanup are adjusted with digital information as well. Unlike a true digital press, which can vary the image on every printed sheet, the image cannot be varied during a press run on a direct imaging press.
