Fig. 1. Multi-slice ECG-gated CT scan (slice thickness, 1.25 mm). (A) Contrast enhanced axial image, the right pulmonary artery was completely occluded by a mass (arrowhead). Endovascular component and extension into the surrounding pulmonary parenchyma were well shown. (B) 3D volume-rendered reconstruction (oblique view) shows the extension (arrowheads) and bronchial artery hypertrophy (arrows...

In this paper, we present a selective scan slice encoding technique for power-aware test data compression. The proposed scheme dramatically reduces test data volume via scan slice repetition, and generates an adjacent-filled test pattern known as the favorable lowpower pattern mapping method. Experiments were performed on the large ITC’99 benchmark circuits, and results show the effectiveness o...

PURPOSE To evaluate the feasibility of a simple estimation for the endolymphatic volume ratio (endolymph volume/total lymph volume = %ELvolume) from an area ratio obtained from only one slice (%EL1slice) or from three slices (%EL3slices). The %ELvolume, calculated from a time-consuming measurement on all magnetic resonance (MR) slices, was compared to the %EL1slice and the %EL3slices. METHODS...

Equations are derived for generating accumulated dose distributions and the dose line integral in a cylindrical dosimetry phantom for a helical CT scan series from the single slice dose profiles using convolution methods. This exposition will better clarify the nature of the dose distribution in helical CT, as well as providing the medical physicist with a better understanding of the physics in...
