Purpose: Recently a new method called TRIPICCS (Temporal Resolution Improved Prior Image Constrained Compressed Sensing) was proposed to improve the temporal resolution of a single source (SS) cardiac CT scan [1] (figures 1+2). This method aims at doubling the temporal resolution and at maintaining homogeneous temporal resolution independently of the location and the motion direction of a vesse...

Over the past decade, computed tomography (CT) theory, techniques and applications have undergone a rapid development. Since CT is so practical and useful, undoubtedly CT technology will continue advancing biomedical and non-biomedical applications. In this outlook article, we share our opinions on the research and development in this field, emphasizing 12 topics we expect to be critical in the...

Magnetic susceptibility (χ) measurements are widely used for the evaluation of soil profile development. Fourteen soil profiles were studied in a relatively wide range of climatic conditions in Fars Province. Citrate-bicarbonate-dithionite (CBD) extraction and micro CT-Scan images were used to evaluate the source of magnetic susceptibility. The results showed that soil samples lost 23 to 91 per...
