Montage motors5/7/2023 ![]() ![]() Often, an abnormality appears only intermittently, in certain head regions, or superimposed on a normal background ( Fisch, 1999). Certain patterns deviating from normal activity are linked to specific diseases. ![]() ![]() Local amplitude reductions are often due to superficial lesions which reduce the electrical potentials generated in the cortex. Local slow waves are often due to circumscribed damage of the white matter, with or without involvement of the cortex. Epileptiform patterns include spike and sharp wave discharges, and they are usually due to a focal irritative lesion of the cerebral cortex. An abnormal EEG contains epileptiform activity, slow waves, amplitude abnormalities, or certain patterns deviating from normal activity. Gail Baura, in Medical Device Technologies (Second Edition), 2021 AnalysisĪ montage is analyzed to determine whether an EEG is abnormal. The simultaneous presentation of images in a montage allows a visualization of continuity of image features in depth, and other spatial relationships. In 3D microscopy, because we are optically sectioning the specimen volume, a montage is the appropriate way to visualize all of the serial cross sections through the specimen simultaneously, rather than visualizing sequential presentations of single sections. Each individual image in the montage is scaled to fit a predefined maximum tile size. The images are tiled on the composite image, in a grid pattern, typically with the name of the image optionally appearing just below the individual tile. A montage display is a composite image created by combining several separate images. These images may be (1) the sequence of serial optical sections in a 3D image stack, (2) a series of projected images, each of which is created by rotating the 3D image to a specific angle, or (3) images from a time-lapse experiment.
