![]() After image normalization, both the calcified area and the area of the plaque adjacent to the calcification that was outside the acoustic shadow were considered. As indicated above, before image normalization, plaques with a calcified cap that had more than 15% of the plaque obscured by an acoustic shadow were classified as type 5. Image normalization was performed by the same members of the team several months later using linear scaling with blood (gray-scale value assigned, 0) and adventitia (gray-scale value assigned, 190) as reference points using Adobe Photoshop™, and the plaques were reclassified without access to the results of the initial classification.

Construction tool, gauge, physics, scientific instrument, vernier caliper icon - Download. Images that were recorded on video tapes (S-VHS) were digitized off-line on a PC using a video grabber card (Videologic, TV Snap version 1.0.3 c 1990–1994) at a resolution of 640 × 480 pixels at the coordinating center by two members of the team who were experienced in carotid scanning. Subsequently, the plaque in the final image was outlined with the mouse and the GSM was obtained from the “histogram” facility. Thus, all the pixels in the image would adjust automatically according to the new linear scale defined by these two reference points. Normalization was subsequently performed using the “curves” facility and adjusting the straight line of the “curves” diagram so that the value of B would become zero and the value A would become 190 in the final image. Also, selecting the inner two fourths of the brightest area of adventitia was essential for ensuring high reproducibility. Zooming so that the area of adventitia was enlarged made this procedure easier to perform. This was achieved by selecting an area of noiseless blood from the vessel lumen and the inner two fourths of the brightest area of adventitia adjacent to the plaque (Fig. There are more than 25 alternatives to Screen Calipers for Windows, Mac, Linux, and SaaS. They probably get used once a day at least, similar to other tools that have become daily staples: Notepad, Photoshop, and Firebug. Briefly, the GSM of blood (B) and adventitia (A) were obtained using the “histogram” facility of the program. The details and reproducibility of this method have been described in several publications.
