About biomedical engineering
Biomedical Engineers topped the technology and science category in the year 2011, according to U.S. news and world report in 50 Best careers. Biomedical is deemed as a career of future!
Well those reading the word “Biomedical Engineering” for the first time would quickly open a new tab and google it!
According to Wikipedia definition “Biomedical Engineering is the application of engineering principles and design concepts to medicine and biology. This field seeks to close the gap between engineering and medicine: It combines the design and problem solving skills of engineering with medical and biological sciences to improve healthcare diagnosis, monitoring and therapy”
The picture shows an X-ray image taken in a Doctor’s office or in Radiologists lab. The X-ray image involves the physical principle of how x-rays interact with tissues of our body, uses physical principle to develop images. It helps to see images inside our body which we couldn’t have seen otherwise. Physicians have over the years learnt to see images and detect abnormalities in bones, ribcage, lungs etc.
During an open heart surgery, the heart lung machine takes over the function of the heart and lungs so that the heart can be carefully stopped. The surgeon can then operate in a blood-free surgical field. Heart lung machine basically replaces the function of heart temporarily.
Consider a situation when there is a case of fever and a doctor cannot decide whether it’s just a viral fever or it’s a case of malaria. Then the doctor would recommend the patient for a medical check up. The patient would then go to a pathology lab where he would get his blood tested and various tests would be conducted on him. Pathologist would then give a report on the basis of tests being conducted. Doctor with the help of these reports will give the required prescription to the patient.
What would have happened if there were no biomedical engineers? None of the sophisticated pathological instruments would have been developed. Hence no doctor would have known if it was a case of malaria or just a viral fever.
X-ray machine, Heart lung machine, a basic stethoscope, an ultrasound sonography machine are all designed by a biomedical engineer.
Belts for neck pain or artificial limb for a person who has undergone amputation are also designed by a biomedical engineer.
Thus it won’t be wrong to say, “Behind a successful doctor there is always Biomedical Engineer”.
The life span of people has increased over the years. More number of people now survive if an epidemic breaks out. Rather than asking the question, why people live longer? A question should be asked, why did people die earlier?
Different Specialties In Biomedical Engineering
The field of biomedical engineering has varying sub-specialties. This will enable you to tap into specialties that you think you are more inclined to. With various sub-specialties to choose from, you can explore more possibilities with your career. The sub-specialties in biomedical engineering are: Bioinformatics, Bio Microelectromechanical Systems, Biosignal Processing, Biomaterials, Biotechnology, Biomechanics, Genomics, Information Technology, Micro and Nanotechnology, Clinical Engineering, Neural Systems and Engineering, Radiology, Sensors, Genomics, Instrumentation, Telemedicine, Physiological Systems and Modeling, Radiology, Proteomics and Robotics in Surgery.
Why there is a massive growth in Biomedical Engineering ?
There is an enormous demand for better medical devices and equipments due to aging and ever increasing population and health issues. Continuous demand of Biomedical engineers include need for highly advanced medical equipments, procedures, reduced costs, easy servicing and maintenance in hospitals and clinics. A 21 per cent growth is projected for biomedical engineers, with an estimated 3,000 new careers created in the industry through 2016 in US.
After getting a brief idea about biomedical engineering, we can say that it gives cutting edge technology to the medical science and it is being constantly upgraded.
