Impact of flexible noise control (FNC) image processing parameters on portable chest radiography
Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract There is a lack of understanding in the performance of flexible noise control (FNC) processing, which is used in digital radiography on a scanner vendor and has four parameters each involving multiple options. The aim of this study was to investigate the impact of FNC on portable chest imaging. An anthropomorphic chest phantom was imaged using

End-to-end simulations of the MUon RAdiography of VESuvius experiment [PDF]
, 2021 The MUon RAdiography of VESuvius (MURAVES) project aims at the study of the summital cone of Mt. Vesuvius, an active volcano near Naples (Italy), by measuring its density profile through muon flux attenuation. Its data, combined with those from gravimetric and seismic measurement campaigns, will be used for better defining the volcanic plug at the ...

Digital Radiography: An Overview [PDF]
The Journal of Contemporary Dental Practice, 2002 Abstract Since the discovery of X-rays in 1895, film has been the primary medium for capturing, displaying, and storing radiographic images. It is a technology that dental practitioners are the most familiar and comfortable with in terms of technique and interpretation. Digital radiography is the latest advancement in dental imaging and is slowly being

Bone construction surgery: A case report using recombinant human platelet‐derived growth factor‐BB
Clinical Advances in Periodontics, Volume 12, Issue 4, Page 262-269, December 2022., 2022 Abstract Background The position and condition of bone largely sets the stage for functional and esthetic implant success. In bone construction surgery, creating a sustainable functional matrix is complex, but necessary, to enable long‐term mechanotransduction and maintenance of soft tissue support.

Evaluation of genotoxic effect of X-rays on oral mucosa during panoramic radiography
Journal of Indian Academy of Oral Medicine and Radiology, 2015 Introduction: X-rays are potent mutagenic agents capable of inducing both gene mutations and chromosomal aberrations. They act directly on the DNA molecule or indirectly through the formation of reactive compounds that interact with this molecule.
