This work presents an alternative scanning geometry for Computed Tomography with Double Optimal Reading, called CT D’OR. With this geometry, the Radon data are acquired after the X-ray beam is collimated through a special mask, which enables an efficient data collection and may reduce the patient dose. We have demonstrated with a test-device that the scanning geometry CT D’OR acquires data for two independent and complementary reconstructions. Additionally, we have shown with a Monte Carlo simulation that the image quality attained using this scanning geometry is equivalent to the one attained by conventional geoametries.
