Endostructural and periosteal growth of the human humerus

open access: yesThe Anatomical Record, Volume 306, Issue 1, Page 60-78, January 2023., 2023
Abstract The growth and development of long bones are of considerable interests in the fields of comparative anatomy and palaeoanthropology, as evolutionary changes and adaptations to specific physical activity patterns are expected to be revealed during bone ontogeny.

Radiologic evaluation of orbital index among Ghanaians using CT scan

open access: yesJournal of Physiological Anthropology, 2017
Background Orbital index (OI) expresses the proportion of the orbital height to the orbital width and varies with race, regions within the same race and periods in evolution. This index is useful in forensic medicine, anthropology and surgery.

Assessment of diagnostic reference levels awareness and knowledge amongst CT radiographers

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine, 2021
Background Reports indicated that numerous factors, including inadequate personnel knowledge, contributes to insufficient patient data for setting up diagnostic reference levels (DRLs) in developing countries. This study aims to evaluate the knowledge of

Multi-energy radiography on the basis of "scintillator-photodiode" detectors [PDF]

open access: yesNucl.Instrum.Meth. A505 (2003) 549-551, 2002
For reconstruction of the spatial structure and thicknesses of complex objects and materials, it is proposed to use multi-radiography with detection of X-ray or gamma-radiation by combined detector arrays of scintillator-photodiode type. Experimental studies have been carried out of the energy dependence of sensitivity of dual-energy inspection systems

RTEX: A novel methodology for Ranking, Tagging, and Explanatory diagnostic captioning of radiography exams [PDF]

open access: yesarXiv, 2020
This paper introduces RTEx, a novel methodology for a) ranking radiography exams based on their probability to contain an abnormality, b) generating abnormality tags for abnormal exams, and c) providing a diagnostic explanation in natural language for each abnormal exam. The task of ranking radiography exams is an important first step for practitioners

Atmospheric neutrinos in the context of muon and neutrino radiography [PDF]

open access: yesEarth Planets Space 62:195-199,2010, 2009
Using the atmospheric neutrinos to probe the density profile of the Earth depends on knowing the angular distribution of the neutrinos at production and the neutrino cross section. This paper reviews the essential features of the angular distribution with emphasis on the relative contributions of pions, kaons and charm.

Evaluation of the dose reduction effect of crystalline lens exposure in cone‐beam computed tomography with bismuth eye shield for image‐guided radiation therapy: An anthropomorphic phantom study

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract This study aimed to evaluate the dose‐exposure reduction effect of a crystalline lens with a bismuth eye shield using cone‐beam computed tomography (CBCT) for head image‐guided radiation therapy. The ocular surface dose of the head phantom (THRA‐1) is defined as a crystalline lens exposure dose and is measured using a radiophotoluminescence ...
