An Exophthalmometer. An exophthalmometer is an instrument used for measuring the degree of forward displacement of the eye in exophthalmos.The device allows measurement of the forward distance of the lateral orbital rim to the front of the cornea. [1]

Exophthalmos (also called exophthalmus, exophthalmia, proptosis, or exorbitism) is a bulging of the eye anteriorly out of the orbit. Exophthalmos can be either bilateral (as is often seen in Graves' disease) or unilateral (as is often seen in an orbital tumor). Complete or partial dislocation from the orbit is also possible from trauma or ...
Magnetic resonance imaging alias Nuclear magnetic resonance : high strength (0.15 to 1.5 teslas) [4] are used to excite protons that produce the record results (like CT scan). It can show particular tissues more clearly than CT.; [4] video link: Linear accelerator: used in radiotherapy for cancer: Functional magnetic resonance imaging (fMRI ...
Medical optical imaging is the use of light as an investigational imaging technique for medical applications, pioneered by American Physical Chemist Britton Chance. Examples include optical microscopy , spectroscopy , endoscopy , scanning laser ophthalmoscopy , laser Doppler imaging , optical coherence tomography , and transdermal optical imaging .
An X-ray tube, a sample scattering the X-rays and a photographic plate to detect them. This constellation forms the scattering instrument used by X-ray crystallography for investigating crystal structures of samples. Amorphous solids lack a distinct pattern and are identifiable thereby.
1960: 160 devices are still in use in the Canton of Zürich. [26] 1970s: By 1970, 33 US states have banned the machine. [9] Late 1970s: Last recorded sighting of a shoe-fitting fluoroscope in service in Boston. [11] 1973: The last devices still in use in West Germany are banned. [27] 1989: Switzerland prohibits the machines. [27]
An optical sensor is generally part of a larger system that integrates a source of light, a measuring device, and the optical sensor. This is often connected to an electrical trigger. The trigger reacts to a change in the signal within the light sensor. An optical sensor can measure the changes from one or several light beams.
