Bone Density Measurement via Radiographic Calibration
… opportunities to make both simple and complex radiographic assessments. We investigated a simple quantitative measurement of the solar, concave aspect of the distal phalanx in the horse, termed the Palmar-Metric (PM). The PM was a significant predictor of solar cup volume (<em>p</em> < 0.001) …

Radiographic applications and control of TNSA proton beams
… work aimed at exploiting these properties for radiographic purposes and exerting control over the ion beam properties for other applications. <br/><br/>A divergent and broadband laser driven proton beam was used in the proton radiography technique to investigate the late stages of the …

Effect of Image Sharpening on Radiographic Image Quality
… that capture and processing of the digital radiographic images may contain artifacts that could reduce the diagnostic value of dental radiographs. This phenomenon has been reported through various case reports. However, its effect on radiographic image quality has not been studied. The …

Panoramic Radiographic Diagnosis of Molar-Incisor Hypomineralization in Permanent Dentition
… between 2016 and 2024, was performed to identify radiographic features suggestive of MIH, including enamel opacity, post-eruptive enamel breakdown, atypical caries, and atypical restorations. A total of 292 radiographs met the MIH inclusion criteria. In the second phase, 50 MIH‑positive …

A Radiographic Analysis of Variance in Lower Incisor Enamel Thickness
The purpose of this study was to help predict the enamel thickness of mandibular incisors. At least two direct digital periapical radiographs were made for each of the 80 subjects. Radiographs were scaled to control for magnification errors using dental study models and computer software. …

Knowledge convergence in collaborative concept mapping among radiographic physics undergraduates
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This study targeted two research questions. First, does collaborative concept mapping enhance group members' knowledge convergence? Second, how does students' participation in interaction influence their knowledge convergence? …

Exploring the Utility of Dental Pathological Conditions in Dental Radiographic Comparisons
Dental forensic identifications can be achieved through comparative dental analysis(CDA) by comparing a decedent's postmortem (PM) dental records to a suspected match's antemortem (AM) dental records. Dental records are particularly useful for CDA, because the number of concordant dental …

Developing a framework of quality in radiographic service delivery in Ghana
… thesis was to develop a framework of quality in radiographic service delivery in Ghana. This aim was to fit the medico-socio-cultural context of Ghana so as to promote the radiographers with additional knowledge about quality issues in the imaging services and patient care. Methods: Mixed methods …

Age estimation in the living: a test of 6 radiographic methods
There is a growing recognition that there is a requirement for methods of age estimation of the living to be rigorously tested to ensure that they are accurate, reliable and valid for use in forensic and humanitarian age estimation. The necessity for accurate and reliable methods of age estimation …

Effect of diabetes and HIV on radiographic manifestations of pulmonary tuberculosis
… A study was conducted to investigate the chest radiographic presentation of pulmonary tuberculosis in patients with diabetes, as well as to analyse the effect of HIV comorbidity on this association. The study was conducted in Khayelitsha, Cape Town, an area with a high tuberculosis, HIV and …

Optimisation of radiation dose and image quality for AP pelvis radiographic examination
… is developed and validated in order to assess radiographic image quality. The scale validation is conducted in two phases; the initial phase uses phantom images and is further tested in phase two with cadaveric images. The scale development and validation is guided by psychometric theory and in …

A combined radiographic and time-of-flight method for zero-knowledge warhead verification
A novel means of combined spectroscopic and radiographic zero-knowledge warhead verification has been developed and investigated using Monte Carlo simulations. This verification approach, henceforth called "epi-ZK," uses time-structured beams of epithermal neutrons to verify weapon isotopics and …
