According to some embodiments, a multimodality diagnostic imaging system having one or more gamma cameras and a flat panel x-ray detector mounted on a common gantry to perform simultaneous FPCT and SPECT studies. The gate oxide film is formed in a thickness having a gate breakdown voltage higher than the element breakdown voltage of a typical field oxide film and the like. The structure may be integrally formed with the proximal face of the septum seal to reinforce the seal, or the structure may be integrally formed with the distal face of the septum seal to tether the seal distally. The method further comprises rotating the assembled module on the holding fixture. The appended information facilitates finding specified information within the document when content mining is performed. Both embodiments include an image correlator for correlating the first and second images and producing an activation signal in response to coincidence of moisture in the respective correlated first and second images.
