Optical Mark Reader forms have been used by the Cardiac Department at St Thomas's Hospital for six years to store clinical and haemodynamic data by computer. Forms are completed by clinical staff in outpatients and also for those patients undergoing cardiac catheterisation. Three documents are used to record the symptoms and signs at the clinical consultation, the results of relevant investigat...

Conventional CT scan the scan is taken slice by slice and after each slice the scan stops and moves down to the next slice eg, from the top of the abdomen down to the pelvis. This requires patients to hold their breath to avoid movement artefact. Spiral/helical CT scan this is a continuous scan which is taken in a spiral fashion. It is a much quicker process and the scanned images are contiguous.

This brief review addresses the existing systems and challenges and provides future recommendations on computerand biosensor-assisted rehabilitation systems for physically disabled patients. We further list the types of sensors, technical issues, and different software and hardware technologies that are currently used in rehabilitation systems to make the whole process dynamic and real-time. Th...

There are internationally agreed optimal methods for developing clinical practice guidelines. The quality of published guidelines varies. A validated assessment instrument should be used to identify well developed guidelines that can be used with confidence. There are multiple ways of presenting guidelines, including computerised systems. Computerisation of guidelines can cover a range of forma...

COMPUTER CRIME, HIGH-TECH CRIME, AND COMPUTER FRAUD ARE ALL terms used to describe the involvement of computers in the commission of crime. Computers have become a common business and household item and come in the form of personal organisers, notebooks, laptops, desktops, networks, mini and mainframe computers. Computer technology has not introduced a new crime but has changed the form of trad...

Generally, computerised tomography (CT) is an X-ray based non-destructive testing method that was developed for medical purposes in the seventies and introduced for industrial applications during the eighties. CT produces maps of the X-ray linear attenuation coefficient of an object’s interior; presented either as cross section images (two-dimensional CT) or as volume information (three-dimensi...

BACKGROUND Major depression is a common mental health problem in the general population, associated with a substantial impact on quality of life and societal costs. However, many depressed patients in primary care do not receive the care they need. Reason for this is that pharmacotherapy is only effective in severely depressed patients and psychological treatments in primary care are scarce and...
