Lung Cancer Screening CT Phantom LSCT0001

Åpne stort bilde

LSCT0001 is a CT phantom developed to facilitate optimizing the radiation dose and other scanning conditions for Lung Cancer Screening CT examination with Helical CT or MDCT, which is aiming at early detection of lung cancers.
As the screening is usually done on healthy people, the necessity of minimizing the exposure while maximizing the image quality is considered to be particularly high.

The phantom is designed to set conditions for detection of small early lung cancers such as GGA, which are difficult to be found by plain X-ray. Anthropologic structure of the phantom provides life-like images allowing operators visual evaluation, while quantitative evaluation on radiation dose and density curve of the image can be done stimulatory with a single scanning.

Teknisk informasjon

The classification of lung sounds is based on the criteria of the American Thoracic Society.

36 cases are available for training. 34 cases include 2 versions -- with and without heart-sounds
NORMAL standard FINE CRACKES both lower area
  mildly weak   both lower and middle area
  mildly strong   whole thorax 1
  mildly rapid   whole thorax 2
  loud heart sounds WHEEZES upper and middle area
ABNORMAL weak: left lower area   around trachea and upper area1
  weak: left whole area   around trachea and upper area2 (polyphone)
  absent: left RHONCHI trachea and upper area
  weak: right lower area   trachea and upper area (polyphonic)
  weak: right lower area   with an inspiratory wheeze
