It is serving as an open source vehicle of the works of researchers in ICT world wide that hitherto would not be available to organisations outside and within the African sub-region. This journal has ceased publication with UTS ePRESS.

Biomedical research increasingly requires for testings be conducted outside the lab, in the field such as the participant’s home or work environment. This type of research requires semi-autonomous computer systems that collect such data and send it back to the lab for processing and dissemination. A key aspect of this type of research is the selection of the required software and hardware components. These systems need to be reliable, allow considerable customizability and be readily accessible but also able to be locked down. In this paper we report a set of requirements for the hardware and software for such a system. We then utilise these requirements to evaluate the use of game consoles as a hardware platform in comparison to other hardware choices.

The paper presents a method of the determining a mandibular cortical width on dental panoramic radiographs. Cortical width of lower border of mandible may potentially be associated with recognition of osteoporosis in postmenopausal women. An algorithm to perform a semiautomatic cortical width measurement in a given region of interest was developed. The algorithm is based on separate extraction of lower and upper boundaries of cortical bone. Results of boundaries extraction performed on 34 panoramic radiographs of healthy and osteoporotic individuals are presented, together with automatic measurements of particular distances. They were compared with results of hand-made measurements done by two maxillofacial radiologists. Presented algorithm may potentially be useful for screening patients with osteoporosis.
