This device can be deployed for acquiring data in computed tomography mode for getting cross-sectional gross density distribution. The mechanical motion of the device may be deployed manually or motorized. Detector and data acquisition system in advanced versions could be used in wireless mode or wired mode. One or two persons can install the device on any cylindrical shaped object of appropriate size. Necessary radiation safety precautions and permissions have to be secured before carrying out the scan.

1. The current invention (Indian Patent no 517803) provides an apparatus for cylindrical shaped specimen for industrial CT scans e.g. industrial process column, cylindrical shapes like drums etc.
2. It can acquire CT data in different orientations like vertical, horizontal, inclined. No access opening required.
3. The device does not require electric supply to move. (Suitable for Petrochemical plants).
4. Baseband and crawler are commercially available from 6 inch to 60 inch (152 mm to 1520 mm). Suitable modifications to ring assembly are required.

1. Useful in qualitative measurement of bulk density distribution inside an object of cylindrical shape in a non-destructive manner.

This device can be deployed for acquiring data in computed tomography mode for getting cross-sectional gross density distribution. The mechanical motion of the device may be deployed manually or in motorized fashion. Detector and data acquisition system in advanced versions could be used in wireless mode or wired mode. One or two persons can install the device on any cylindrical shaped object of appropriate size. Necessary radiation safety precautions and permissions have to be secured before carrying out the scan.

The device is designed keeping in mind the radiation safety and orientation of the cylindrical objects and geometric irregularities on the surface. It is aimed at finding gross density distribution across the sample helping in troubleshooting by non-destructive method.

The apparatus and its method of using is based on the principle of industrial computed tomography. Data pertaining to attenuation of gamma radiation is acquired 360 degree around an object using radiation source of appropriate strength and multiple scintillation detectors like NaI (Tl) with a Single channel analyzer based data acquisition system. The data acquired properly can then be processed separately on a computer using image reconstruction software for diagnosis and troubleshooting, if necessary.
