Scanning laser ophthalmoscopy developed as a method to view a distinct layer of the living eye at the microscopic level. The use of confocal methods to diminish extra light by focusing detected light through a small pinhole made possible the imaging of individual layers of the retina with greater distinction than ever before.

A retinal scan is performed by casting an unperceived beam of low-energy infrared light into a person’s eye as they look through the scanner's eyepiece. This beam of light traces a standardized path on the retina. Because retinal blood vessels absorb light more readily than the surrounding tissue, the amount of reflection varies during the scan.
The objective of cancer screening is to detect cancer before symptoms appear, involving various methods such as blood tests, urine tests, DNA tests, and medical imaging. [1] [2] The purpose of screening is early cancer detection, to make the cancer easier to treat and extending life expectancy. [3]
The Heidelberg Retinal Tomography is a diagnostic procedure used in ophthalmology.The Heidelberg Retina Tomograph (HRT) is an ophthalmological confocal point scanning laser ophthalmoscope [1] for examining the cornea and certain areas of the retina using different diagnostic modules (HRT retina, HRT cornea, HRT glaucoma).
Retinal birefringence scanning (RBS) is a method for detecting the central fixation of the eye. The method can be used in pediatric ophthalmology for screening purposes. By simultaneously measuring the central fixation of both eyes, small- and large-angle strabismus can be detected. The method is not invasive and requires little cooperation by ...
The cost of using ultrasounds tech costs around 10% of MRI scanning, which means doctors can now better guide prostate biopsies and focal therapy – which destroys cancer cells, the research team ...
The catalogue includes the pathology specific to the biomarkers, the investigator(s) involved in creating and using the biomarker, and the modalities used in the detection of the biomarker. International Cancer Biomarker Consortium was created to assist in discovery of biomarkers by facilitating coordinated research and by leveraging resources.
A variant of optical tomography uses optical time-of-flight sampling as an attempt to distinguish transmitted light from scattered light. [4] This concept has been used in several academic and commercial systems for breast cancer imaging and cerebral measurement.
