WebThe 4DCT scanning was performed in the helical mode with the scanning pitch set at 0.09–0.15. The respiratory signals were sent to the scanner to label each 4DCT image with a time tag. GE Advantage 4D software (General Electric Healthcare, Waukesha, WI, USA) was used to sort the reconstructed 4DCT images into ten respiratory phases based on these … WebWith single-beam scanning sonar, the smaller and narrower the horizontal beam, the better the resolution. Two versions of single-beam sonar heads: high-resolution and domed. …
