Claim Text:
1. A method comprising: positioning a plurality of sources of x-rays at a selected location outside a closed, windowless, metal wall surrounding a flow of gas, liquid, or solid particles, positioning a plurality of detectors outside the closed metal wall at respective locations suitable to detect x-rays passing entirely through the closed metal wall and a portion of a volume surrounded by the closed metal wall, each of the detectors having a plurality of sensors arranged in at least one row, capturing a plurality of respective view angles from the respective detectors to represent a dimensionally distributed view of gas, liquid, or particle density, outputting data from the detectors reflecting the distributed view, coupling a processor to the output of the detectors to analyze the data, detecting, with the processor, variations in gas, liquid or particle density within the volume surrounded by the closed metal wall based on deconvolution of the data by the processor; and providing a display to show results of the processor analysis.
