As indicated at the bottom of this page, there is a significantly large number of graphic word-entry groups in this unit. Such an extensive listing is provided to show how important the grapho- element is to the English language.

thaumatography (s) (noun), thaumatographies (pl)
A writing or written materials concerning the wonders of nature or natural wonders.
1. In physics, an instrument for recording simultaneously the pressure and temperature of a gas; a combination of a thermograph and a barograph.
2. An instrument that simultaneously records variations in temperature as well as atmospheric pressure.
thermogeographical, thermogeographic
A reference to the study of the geographical variations and distributions of temperatures.
The study of the geographical distributions and variations of heat.
1. A self-recording thermometer that measures both air and soil temperature on a continuous display known as a thermogram.
2. A photographic record of the amount of heat radiated from the surface of a body, revealing "hot spots" of potential tumors or other disorders.
3. An instrument consisting of a thermometer, an inked stylus, and a chart for the continuous recording of the ambient or surrounding-air temperature.
4. Essentially, a self-recording thermometer that continuously records the temperature on a chart.
Someone who produces a thermogram or a technique for detecting and measuring variations in the heat emitted by various regions of the body and transforming them into visible signals that can be recorded photographically; as for diagnosing abnormal or diseased underlying conditions.
1. In medicine, a technique wherein an infrared camera is used to photographically portray the surface temperatures of the body, based on the self-emanating infrared radiation; sometimes employed as a means of diagnosing underlying pathologic processes, such as breast tumors.
2. The technique for making a thermogram or an image, or record, of the heat radiating from the body.
3. A procedure for sensing and recording on film the hot and cold areas of the body by means of an infrared detector that reacts to blood flow and produces images that reveal sites of abnormal tissue growth.

Disease conditions which show increased or decreased blood flow that presents thermographic patterns which can be distinguished from those of normal areas.

The use of thermography in the diagnosis of lesions of the breast.
Now considered an obsolete method for determination of placental position by detection of infrared rays from the large amounts of blood flowing through the placenta.
An instrument for determining the horizontal contour of the chest.
An instrument for plotting and recording the contour of the thorax and the lungs during inspiration and exspiration.
tocodynagraph, tokodynagraph
A device for measuring the intensity of uterine contractions.
tocograph, tokograph
A recording taken with tocodynamometer, or tokodynamometer, an instrument for measuring and recording the expulsive force of uterine contractions.
tokography, tocography; tocoalgography
1. The recording and interpreting of the expulsive force of uterine muscular contractions during labor.
2. The making and interpreting of graphic recordings of the amplitude, duration, and frequency of uterine muscular contractions during child labor.
The process for generating a tomogram, a two-dimensional image of a slice or section through a three-dimensional object.

Tomography achieves this remarkable result by simply moving an x-ray source in one direction as the x-ray film is moved in the opposite direction during the exposure to sharpen structures in the focal plane, while structures in other planes appear blurred.

The tomogram is the picture; the tomograph is the apparatus; and tomography is the process.
