BACKGROUND Accurate measurements of knee and hip motion are required for management of musculoskeletal pathology. The purpose of this investigation was to compare three techniques for measuring motion at the hip and knee. The authors hypothesized that digital photography would be equivalent in accuracy and show higher precision compared to the other two techniques. METHODS Using infrared moti...

Digital imaging has made major inroads into the routine practice of anatomical pathology and replaces photographic prints and Kodachromes for reporting and conference purposes. More advanced systems coupled to computers allow greater versatility and speed of turnaround as well as lower costs of incorporating macroscopic and microscopic pictures into pathology reports and publications. Digital i...

UNLABELLED The emerging market of digital cephalographs and computerized cephalometry is overwhelming the need to examine the advantages and drawbacks of manual cephalometry, meanwhile, small offices continue to benefit from the economic efficacy and ease of use of analogue cephalograms. The use of modern cephalometric software requires import of digital cephalograms or digital capture of analo...

By looking at both the formal and informal dissemination of archaeological photography this paper will examine the way that digital images are shared and recorded. The influence that this technology has had on working practice will be explored. Through the examination of images on Flickr and Facebook issues of user engagement and data quality will be discussed. This will then be compared agains...

Digital photography has the potential to supersede conventional film photography. In order to realize this potential, digital photography needs to provide the best image quality and highest utility. We have used our modeling of photographic systems and our experimental measurements of CCDs in order to estimate the photographic potential of specific CCDs. We have also extrapolated the future req...

BACKGROUND Cosmetic surgery and photography are inseparable. Clinical photographs serve as diagnostic aids, medical records, legal protection, and marketing tools. In the past, taking high-quality, standardized images and maintaining and using them for presentations were tasks of significant proportion when done correctly. Although the cosmetic literature is replete with articles on standardize...

BACKGROUND Digital photography has simplified the process of capturing and utilizing medical images. The process of taking high-quality digital photographs has been recognized as efficient, timely, and cost-effective. In particular, the evolution of smartphone and comparable technologies has become a vital component in teaching and learning of health care professionals. However, ethical standar...

Different digital cameras have different spectral sensitivities and opto-electronic conversion functions (OECF’s), and therefore produce different data about the same scene. Correct interpretation of the data requires that it be presented in some sort of standard form. The most rigorous way to do this is to provide the raw data along with the camera color channel OECF’s and spectral sensitiviti...

Second Life (SL) is an emerging technology in higher education. Academics are showing strong interest in it, but so far have more imaginative ideas about using it than experience of actual practice. This paper reports on a pilot study of using SL with six undergraduate students studying Digital Photography in October 2008 at the London South Bank University. The students took part in a group ac...

Background Digital photogrammetry provides measurements of body angles or distances which allow for quantitative posture assessment with or without the use of external markers. It is becoming an increasingly popular tool for the assessment of the musculoskeletal system. The aim of this paper is to present a structured method for the analysis of posture and its changes using a standardized digit...
