A kymograph (from Greek κῦμα, swell or wave + γραφή, writing; also called a kymographion) is an analog device that draws a graphical representation of spatial position over time. The graphical representation is a graph in which the y axis shows position and the x axis shows time.
A kymograph is the two-dimensional representation of position versus time, taken directly from imaging data (Fig. 8.3 B and D). In a kymograph, individual mitochondria appear as lines, and their average velocity is the slope of the line ( De Vos & Sheetz, 2007; Miller & Sheetz, 2004 ).
In physiology: Historical background. In 1847 he invented the kymograph, a cylindrical drum used to record muscular motion, changes in blood pressure, and other physiological phenomena. He also made significant contributions to the physiology of circulation and urine secretion.
Depth-kymography is the 3D display of the human vocal fold vibrations by measuring their vertical and horizontal movements simultaneously, using a specially designed 3D endoscope. This 3D imaging method and the scientific term "Depth-Kymography" were introduced by Dr. Nibu A George, Prof. Frits de Mul and Prof. Harm Schutte.
Kymograph. Usage Conditions Apply. Description: Historians of science and medicine understand that “By the turn of the twentieth century, kymographic recording apparatus had become the central tool of physiological analysis and the symbol of a new style of pedagogy especially in American medical schools.”

Apr 20, 2016 · A kymograph is a time–space plot in which the intensity along a given track is plotted as a function of time. Particles moving with constant velocity show up as straight lines, with the slope representing velocity, whereas diffusing particles produce more complex, sinuous trajectories.
Jun 6, 2016 · KymographDirect is a stand-alone tool to extract quantitative information from kymographs obtained from a wide range of dynamic processes in an automated way, with high accuracy and reliability. We discuss the concepts behind these software tools, validate them using simulated data, and test them on experimental data.
