Biomedical engineering is an unavoidable part of medical sciences and biological science. It is actually a hybrid discipline that is formed by combining the engineering discipline and biological discipline. For executing researches on biology and medical science, application of sophisticated technology is essential. And those respective required technology is designed and provided under the biomedical engineering discipline.
Nowadays, medical science and biological science are not capable of performing at the highest level without support of biomedical engineering. The modern and sophisticated equipments (CT scanner, ultrasound image generator) are designed and manufactured under the guidance of biomedical engineering. At present, biomedical engineering is a highly recognized discipline with extensive application and employment opportunities through the world.
Medical science and different biological discipline form the very has been using mechanical or electrical devices to perform several kinds of researches. Previously those required devices were used to be designed and made by the engineers, who had little knowledge on biological aspects. For this reason, designing of those devices was very cumbersome and often resulted in miscommunication between the biologists / medical professionals and the respective engineers.
As a result the produced device, under that process, was often not up to the expected standards. The concerned professionals realized that, for designing high quality devices for biological applications, a set of professionals with understanding of both biology and engineering is needed for efficient and effective designing of required devices. Therefore, a separate discipline, which is a cross of engineering and biology, was proposed and thus the biomedical engineering started its glorious journey on the earth.
Today biomedical engineering is a largely expanded discipline. For bringing more efficiency and professionalism, the biomedical engineering is now divided into several sub disciplines. Some notable sub disciplines are: biomedical electronics, neural engineering, clinical engineering, medical imaging, bio-transport etc.
The applications of Biomedical engineering are seen everywhere in the contemporary world. the medical imaging concerns such as , ultrasound , CT scan , optical microscopy or electron microscopy , nuclear medicine etc are heavily depended on the biomedical engineering ( particularly on medical imaging that is its sub discipline ) for the designing required devices and systems . Genetic engineering, tissue engineering, pharmaceutical engineering and all other sectors, which require technology intensive devices for dealing with biological stuffs, are obvious consumer of biomedical engineering applications.
The manufacturing industries are largely depended on the biomedical engineering. The devices and systems, designed under the supervision of biomedical engineering, are generally very expensive and in high demand by the hospitals, health care institutions, pharmaceuticals companies. A large manufacturing industry has been built up around those devices. Those manufacturing facilities are making extensive use of different aspects of biomedical engineering.
