X-ray computed tomography (CT) has been applied to visualize tree rings in a non-invasive way for dendrochronological research. For large objects such as chests or cabinets, it is often impossible or impractical to rotate fully within the scanner as is necessary for CT. As a solution to this challenge, we developed a line trajectory X-ray tomography technique, in which the object is moved only sideways. We show that this
method, although not yielding a full 3D image, is particularly well suited to reveal tree rings. Using this easily implementable scanning
