The tools can be categorized in a number of ways: simple optical borehole imaging (OBI) systems, energy source (electrical, acoustic, or nuclear with gamma rays or neutron); conveyance (wireline or logging while drilling); and type of drilling mud (water-based mud or oil-based mud).
MAGIC, a Cherenkov telescope in operation on the Canary island of La Palma.On foggy nights, the lasers that are used to focus the mirrors can be seen. IACT (imaging atmospheric [or air] Cherenkov telescope [1] [or technique] [2] [3]) is a device or method to detect very-high-energy gamma ray photons in the photon energy range of 50 GeV to 50 TeV.
Two of the key challenges are improving the speed and reliability of the DVC measurement. The 3D imaging techniques produce noisier images than conventional 2D optical images, which reduces the quality of the displacement measurement. Computational speed is restricted by the file sizes of 3D images, which are significantly larger than 2D images.
Preserving the angle requires a precise planar and rectangular cross section of the radiator. Knowledge of the angle at which the radiation was produced, combined with the track angle and the particle's momentum (measured in a tracking detector like a drift chamber ) may be used to calculate the particle's mass.
Medical imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues . Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease.
Please help improve this article by introducing more precise citations. ( September 2013 ) ( Learn how and when to remove this message ) Image analysis or imagery analysis is the extraction of meaningful information from images ; mainly from digital images by means of digital image processing techniques.

Image guided surgery systems use cameras, ultrasonic, electromagnetic or a combination of fields to capture and relay the patient's anatomy and the surgeon's precise movements in relation to the patient, to computer monitors in the operating room or to augmented reality headsets (augmented reality surgical navigation technology).
