A2. Calibrate the image. For one frequency, make distance measurements between 1 level, 2 levels and 3 levels. How does this compare to expected distance? Use the percent difference formula. Make a table of distance results (place table in results section). Hint: The purpose of calibration is to determine how accurate the images are. The image we use is 2.5, 3.5, and 5 MHz stack images. Technically, it's supposed to be the same distance (between each level) which is the 2 cm. 50, I want you to measure the distance with lmageJ, then compare your distances to expected distance (2 cm). Finally, provide percentage. For example, if you get 1.8 cm and 2.2 cm, l 21.8 2 |x100 1 O % 10% ltjzlxloo Anechoic Target Structures.tif Images taken from the top Medial: Target Structures _m IIIIIIIIIIIEEIIIHIHWIII _\" _ _m Dep 2o - 170 mm Interval Spacing Centermanta 20 mm
