Chest CT images were obtained with a GE Lightspeed/16-slice scanner. The scanning parameters were as follows: 120 kV; 100 mAs; pitch was 1.2 mm. rotation time: 0.5 s; matrix size: 512 × 512, thickness: 5.0 mm.
Lightspeed 16 slice scanner
Manufactured by GE Healthcare
The Lightspeed/16-slice scanner is a computed tomography (CT) imaging system manufactured by GE Healthcare. It is capable of acquiring 16 slices of image data simultaneously, allowing for rapid data acquisition and reconstruction. The system utilizes advanced detector technology and a high-performance X-ray tube to generate high-quality, detailed images for medical diagnostic purposes.

Chest CT examinations were performed using a GE LightSpeed/16-slice scanner. CT scanning parameters were the same as those of the chest: 120 kV, 100 mA, 5 mm thickness and slice interval, and standard lung window (window width, 1500 HU; window level, -700 HU) were selected. Within 7 days after taking PQ, a chest CT examination was performed every average of 3 days.

The CT scans were obtained through the use of 2 dedicated mobile scanners (93%) or, beginning in 2012, at 2 imaging facilities in Las Vegas and Idaho Falls (7%).
From 2000 to 2006, a coach-mounted, single-slice General Electric HiSpeed DX/I (GE Medical Systems, Milwaukee, WI) was used to obtain full-chest, helical CT scans with a low-dose technique (120 kilovolt peak [kVp], 40-50 milliamps, pitch of 1.5, 7-millimeter collimation). From 2006 to 2013, we performed CT scanning with Siemens Emotion 16, 16-slice scanners (Siemens, Malvern, PA) at most program sites, supplemented by a Siemens Sensation 64 scanner in Las Vegas and a General Electric Lightspeed 16-slice scanner in Idaho Falls in 2012. We selected kilovolt peak, tube current, pitch, and other scanner parameters to produce a CT dose index for a standard-sized patient, which was within the guidelines for low-dose chest CT scan (1.5-2.3 mGy). The average estimated effective dose across all scanners was 1 millisieverts (range = 0.8-1.2 mSv).
Of 16 229 scans, 90% (14 674) were interpreted by a single senior academic thoracic radiologist (J. M.), and the remaining scans were read by experienced radiologists in DOE communities.

CT Scan Analysis of Ancient Mummies

The team that examined the mummies consisted of an Egyptologist and mummy specialist (B.B.), two radiologists (P.V. and M.S.), a radiologic technician (H.M.), and an X-ray technician (E.J.). The first step was to CT scan and X-ray the two mummies. Imaging was performed at the Albany Medical Center on a GE LightSpeed 16-Slice scanner capable of producing high-resolution images (Fig. 3). The thin axial slices generated from the CT scan allow for two-dimensional reformatted and threedimensional images to enhance visualization of the mummy's anatomy. Since little or nothing was known about the unwrapped mummy, especially after the identity of wrapped mummy was determined, most research effort was directed towards the analysis of the wrapped mummy, the probable Ankhefenmut. Using these X-ray analyses, several parameters of the wrapped mummy were evaluated: sex, age at death, function of an artificial and perhaps prosthetic toe, and exploration of the details of the mummification process.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
