Sample text

5 ATO may be applied during real-time B-mode scanning or after an image has been frozen on the screen. Figure 2â 3 Automated image enhancement. Image on the left was obtained with standard settings. After the image was frozen on the screen, the "automatic tissue optimization" control was selected, resulting in image on right. Arrow points to metastasis in liver. Note the greater contrast between adjacent tissues of slightly different echodensity in the image on the right. ) Tissue Harmonic Tissue harmonic imaging takes advantage of the fact that as sound waves of a given frequency pass through tissue, harmonics are produced within the tissue at multiples of the initial frequency.

Most currently available emergency ultrasound systems have a slot in the cart designed to accommodate a thermal printer. 75 to 5 in. wide. Brightness and contrast can be adjusted on the printer to match the printed image to the image on the display monitor. Different grades of 44 45 thermal paper are available. The dynamic range capabilities of thermal printers and quality of paper has improved a great deal since their inception and when properly adjusted, thermal images provide an acceptable means to view the information as it was displayed on the ultrasound screen.

Figure 2â 10 Convex transducer, side and oblique views. ) Figure 2â 11 Microconvex transducer, side and front views. ) Phased Array Probes 41 42 Phased array probes generally have small heads, similar to microconvex transducers, but instead of being curved, the heads are flat (Figure 2â 12). The crystals in their heads are arranged in a linear array. By changing the timing in which the crystals are fired, the machine alters the direction of the composite ultrasound beam. For each frame displayed on the screen, the beam is swept once across the tissue, giving a sector-shaped image, much like that produced by a mechanical or microconvex probe.
