riskPointer - Features

Pulmonary emphysema, a type of chronic obstructive pulmonary disease, is an illness that involves damage to the alveoli walls caused primarily by smoking. By setting the appropriate threshold value, pulmonary emphysema can be visualized as LAA on CT images.

The riskPointer displays the low attenuation area corresponding to the destruction of the alveoli walls in the lung field in different colors. Details can be shown visually for easy understanding compared with conventional explanations with values.

With conventional software, manual settings such as ROI setting around the lung field needs to be done. With the riskPointer, the low attenuation area (LAA) is processed with a color based on the threshold value which is set by the user and the calculated results of %LAA are displayed in a short period of time.

There are two types of analysis modes. With Upper/Middle/Lower Lung Field mode, the selected three cross sections can be analyzed as in the general CT examination of pulmonary emphysema. The Entire Lung Field mode allows the analysis of whole lung images obtained during chest CT checkups.

Patient’s past examination results can be retrieved and added to current examination report, and this allows user to see the change of %LAA at a glance. Analyzed images can be generated in color DICOM format, BMP format, and analysis value in the text format (CSV).
