Medical imaging comprises different imaging modalities and processes to image human body for diagnostic and treatment purposes and therefore has an important role in the improvement of public health in all population groups. Furthermore‚ medical imaging is justified also to follow the course of a disease already diagnosed and/or treated. Area of medical imaging is very complex and‚ depending on a context‚ requires supplementary

Aphasia is a language disorder that results from damage to portions of the brain that are responsible for language. For most people‚ these are parts of the left side (hemisphere) of the brain. Aphasia usually occurs suddenly‚ often as the result of a stroke or head injury‚ but it may also develop slowly‚ as in the case of a brain tumor. The disorder impairs the expression and understanding of language as well as reading and writing. "Aphasia may co-occur with speech disorders such as dysarthria or

Secondly‚ Professor Adrian Raine‚ a leading psychologist at the University of California used magnetic resonance imaging to study the brains of people with less lethal anti-social personality disorders.

A phantom limb is the belief that a limb that has been removed or amputated is still present in the body and performing its normal functions. Amputees usually experience sensations including pain in the phantom limb. It is estimated that more than 80% of patients with partial or total loss of a limb develop chronic phantom-limb pain (PLP)‚ pain that seems to be located in the missing limb. Risks factors for PLP include gender (PLP being more common in women)‚ upper extremity amputation‚ presence

Computers play a key role in almost every sphere of life. They facilitate storage of huge amounts of data‚ they enable speedy processing of information and they possess an inbuilt intelligence‚ which if supplemented with human intellect‚ can work wonders. Owing to their intelligence and speed‚ computers function on a level close to that of the human brain. Computers can hence be employed in different fields like engineering‚ data processing and storage‚ planning and scheduling‚ networking‚ education
