    During the past two years, a new High Resolution Gamma Ray Detector Array System to detect and measure small corrosion pits in real-time in the inservice piping in process industries, has been in development. This High Resolution Gamma Ray Detector Array can be substituted in place of the standard detector array in our ThruVU (TVU) system. The first High Resolution detector array has a total width of 1.00" and consists of 76 channels with 0.013" detector pitch. On the other hand, the detector pitch is 0.130" in the standard TVU detector array. So, the new High Resolution detector array can potentially provide a 10x better spatial resolution compared to the TVU standard detector array.

    In May 1995, Omega International Technology, Inc., began testing a new system to measure pipe wall thicknesses using digital radiography (RT) scanning. This new system has the potential for being faster, less labor intensive, and shown improved accuracy over traditional ultrasound testing, and at a lower cost. Perhaps best of all, scanning can be performed while the pipe is in service, insulation in place.
