Body surface scanner for the abdominal sound speed tomographic imaging

The Journal of the Acoustical Society of America, 2012
The ultrasound tomography has been studied for the reconstruction of the abdominal sound speed image to measure the visceral fat area. The method is based on the travel time observations of the sound waves transmitted through the abdominal medium. In the present study, aiming to realize the method as a clinically available equipment, body surface ...

[Scanner-guided biopsy technic with abdominal compression].

Journal de radiologie, 1999
The aim of this study was to present a CT-guided biopsy technique using an abdominal compression device. With this system, the digestive structures (mainly the colon and the small bowel) can be displaced away from the needle track and the distance between the skin and the target lesion can be reduced by approximately one-third.

[Use of a constant-flow 2-phase injector for abdominal scanners in 60 patients].

Journal de radiologie, 1992
The intravenous injection of a contrast medium is carried out in more than 80% of all the patients undergoing abdominal CT. The use of a constant-flow two-phase injector has several advantages in practice: possibility to vary the injections, safety, easy use, reproducibility, overall quality of the results and possibility to reduce the dose of contrast

Quality of routine diagnostic abdominal images generated from a novel detector-based spectral CT scanner: a technical report on a phantom and clinical study

Abdominal Radiology, 2017
To evaluate the image quality of routine diagnostic images generated from a novel detector-based spectral detector CT (SDCT) and compare it with CT images obtained from a conventional scanner with an energy-integrating detector (Brilliance iCT), Routine diagnostic (conventional/polyenergetic) images are non-material-specific images that resemble single-

[New abdominal CT angiography protocol on a 16 detector-row CT scanner - first results].

Der Radiologe, 2003
Purpose of this study was the implementation of a new abdominal CT angiography protocol on a 16 detector-row CT scanner and the comparison to selective catheter angiography.76 patients with various vascular disorders underwent abdominal CT angiography on a recently developed 16 detector-row CT scanner using submillimeter slice collimation (16 x 0.75 mm)

[Tomographic study of the intra-abdominal digestive tract. Contributions of percutaneous echography and scanner in daily practice].

Journal de radiologie, 1996
Endoscopy and radiological imaging are complementary. However the gastro-intestinal tract is routinely being imaged in CT and ultrasound, often performed for other indications. When an abnormality is discovered, several questions have to be addressed. Is the lesion due to a bowel abnormality?
