Figure 7-3 The Olympus EU-M20 Image processor (lower arrow) is rack-mounted in a standard cart, which includes the other essential endoscopic equipment. The keyboard (upper arrow) can be used to measure and mark ultrasound findings.
Figure 7-5 The esophageal wall is visualized as five alternating layers of differing echogenicity by esophageal ultrasound. The first layer, which is hyperechoic (white), represents the superficial mucosa (epithelium and lamina propria). The second layer, which is hypoechoic (black), represents the deep mucosa (muscularis mucosa). The third layer, which is hyperechoic (white), represents the submucosa. The fourth layer, which is black (hypoechoic), represents the muscularis propria. The fifth layer, which is hyperechoic (white) is the paraesophageal tissue.
