tomographn.

Brit.

/ˈtəʊməɡrɑːf/,

/ˈtəʊməɡraf/,

/ˈtɒməɡrɑːf/,

/ˈtɒməɡraf/, U.S.

/ˈtoʊməˌɡræf/

Origin: A borrowing from Greek, combined with an English element. Etymons: Greek τόμος , -graph comb. form.

Etymology: < ancient Greek τόμος slice, section (see tome n.) + -graph comb. form. In sense 1 (denoting the apparatus) probably after German Tomograph (1934 or earlier). Compare tomography n. and (with sense 2) slightly later tomogram n.

1. A device or machine used for making tomographic images of the internal structure of something, typically operating by means of one or more sensors which can detect and record the passage of electromagnetic waves, electrons, etc., through the object from multiple angles.

1935 Brit. Jrnl. Radiol. 8 750 A new device, the tomograph, is described, which permits the radiography of body layers of any size and variable thickness.

1980 New Scientist 31 July 420 Equipment includes four gamma cameras, a rectilinear scanner, a whole body counter, an emission tomograph and two dedicated computer systems.

2009 P. Cumming Imaging Dopamine i. 18 The tomograph consists of circular rings of these detectors, positioned so that the subject's head is near the center of the aperture of the detector ring.

2. A tomographic image of the internal structure of something; a tomogram. Now somewhat rare.
