Iterative reconstruction (IR) methods have recently re-emerged in transmission x-ray computed
tomography (CT). They were successfully used in the early years of CT, but given up …

The human intervertebral disc acts as an osmotic system. Water, salt, and other low-molecular
substances penetrate the cartilage plates and annulus fibrosus. The content of water, …

… Comparison of simulations with 300 and 100 μm focal spot size at 3 mGy AGD and FBP
reconstruction (a–d). Significant differences are visible only for the μCa reconstruction with the …

Purpose: With recently introduced technical innovations for CT systems, the dose of CT scan
acquisitions has been substantially reduced; even effective dose values below 1 mSv have …

… ; these are as well seen by digital mammography (d) and breast tomosynthesis (e). The
regions of … (b, d) Maximum intensity projections with a section thickness of 4.5 mm; (c, e) were …

Purpose: Monte Carlo (MC) simulation is an established technique for dose calculation in
diagnostic radiology. The major drawback is its high computational demand, which limits the …

Tissue-and water-equivalent materials (TEMs) are widely used in quality assurance and
calibration procedures, both in radiodiagnostics and radiotherapy. In radiotherapy, particularly, …

Purpose In the last five years digital volume tomographs (DVT) have found their way into the
diagnostic imaging of the facial skull. In this study both the image quality and dose of DVT …

… Additionally as a comparison, (c) image of an SQ scan and (d) image of an HQ scan. …
Plot of the fractional dose with respect to (c) the fractional size and the noise level and (d) the …

Background— The developmental mechanisms underlying the persistence of myocardial
accessory atrioventricular pathways (APs) that bypass the annulus fibrosis are mainly unknown…
