Briefly, an axial CT scan at the level of the umbilicus was obtained for each participant using an electron beam CT scanner (commercial available software).
Using an electron beam CT scanner, Dakin and colleagues [ 95] analyzed the distribution of parenchymal consolidation and tissue perfusion in healthy and ARDS patients.
Two sets of images for scoring of CAC were obtained using an ultrafast Imatron C-150XLP electron beam CT scanner (Imatron, San Francisco, CA).
Body composition was assessed using BMI (weight [kg]/height [m]), and abdominal adipose tissue distribution (visceral, subcutaneous, and total) was measured with a 150 electron beam tomography scanner (Imatron, San Francisco, CA).
CT was performed in 19 scanning sites using a C-150 cardiac-gated electron beam CT scanner (n = 9; Imatron, San Francisco, CA), a Lightspeed (n = 7; General Electric Medical Systems, Waukesha, WI), or a Volume Zoom (Siemens, Erlanger, Germany) multidetector CT system; a Lightspeed Marconi MX-8000 (GE); or a Somatom 4 (Siemens) (n = 3).
GE Medical Systems, a unit of the General Electric Company, said yesterday that it had agreed to acquire Imatron Inc., a San Francisco-based pioneer of electron beam tomography scanners, for about $200 million.
Two sets of high-resolution noncontrast contiguous 3-mm tomographic images were acquired at 0.1-s exposure on an Imatron C-150XLP electron-beam CT scanner (Imatron, San Francisco, CA) as described previously (4).
Models for percent emphysema also included a categorical term for CT scanner (electron-beam, non-Siemens multidetector, Siemens multidetector) and an interaction between body weight (≤ 220 lb or > 220 lb) and CT scanner since the radiation was increased 25% for individuals > 220 lb.
Access to cutting-edge imaging technology, including a high resolution micro-CT scanner, scanning electron microscopes, imaging software, and 3D printers, through Duke's Shared Materials Instrumentation Facility.
Two sets of images for scoring of CAC were obtained using an ultrafast Imatron C-150XLP electron beam computed tomography scanner (Imatron, San Francisco, CA).
