Welcoming Address Dear Colleague,

It is a pleasure to welcome you in Salt Lake City for the third edition of The International Conference on Image Formation in X-ray Computed Tomography, also known as “The CT meeting”. The idea for this meeting came about six years ago, following a wish from many to have a venue where CT scientists could meet together to discuss in depth all aspects that impact the image formation process in CT. These aspects include dose evaluation and dose reduction strategies, non-linearity effects and compensation schemes for these effects, image reconstruction algorithms, spectral decomposition, dynamic effects, geometrical calibration, phase-contrast physics, and image quality assessment. Pleasantly, the meeting this year attracted a few more submissions than in 2012. However, in an effort to further increase the quality of the presentations, which is already very high, and to also increase the merit of receiving a classical poster presentation, the bottom 5 % of submissions was rejected. Whereas 57 presentations were given at the first meeting, in 2010, and 104 at the second meeting, in 2012, 105 presentations will be given this year, including a special session on homeland security applications. The breadth of the topics being covered is amazing. I am grateful to all authors for submitting their work. As in 2010 and 2012, oral presentations have been allocated significant time to allow for in-depth discussion between the attendees. Also, comfortable poster sessions have been planned, and attractive locations have been selected to promote discussion during the meals
