Abstract
We have been developing a focal plane x-ray tomography system that will be capable of creating limited angle tomograms in real-time at rates as high as 60 per second. The intended application of the device would be in coronary angiography, where conventional tomographic systems are too slow to capture sharp images of the beating heart. We first reported on this system development three years ago. Since that time, we have been constructing and testing sub-system components while awaiting the completion of the design, construction and testing of the "Tomotron" x-ray tube, which is being manufactured by the Eimac Division of Varian Corporation. We anticipate that the x-ray tube will be ready for integration into the tomography system this spring. In this report, we would like to describe the overall system design and present some of the performance characteristics of three of the sub-system components: image deflection mechanism, x-ray collimator and anti-scatter grid.
