Today, there are various technologies that enables medical practitioners to see our internal body systems such as the digestive, circulatory and respiratory systems. There are also many technologies that help treat any problems that are found in our bodies.
An example of a technology that helps doctors see inside our bodies is Ultrasound. Ultrasound images, or sonograms, use high-frequency sound waves to produce a picture of parts withing our bodies. Ultrasounds are captured in real-time, so the structure and movement of internal organs and blood flow can be seen. Ultrasounds are not painful and do not use radiation like x-rays.
Computed tomography (CT or CAT) scanning combines powerful computers and x-ray equipment to create images of the body's insides. These pictures can be examined on a computer monitor, printed or transferred on a CD.
CT scans are used to look for:
- Internal bleeding
- Broken bones
- Signs of cardiovascular disease
- Cancer
- Trauma
An example of a technology that helps treat health problems is Insulin. The insulin was invented by two Canadian doctors, Charles Best and Frederick Banting. Insulin is an injection used to control blood sugar for people who are diagnosed with type 1 diabetes or people who have type 2 diabetes that can't be controlled only by medications. The injection is used to take the place of insulin that is normally produced in the body and also helps to move sugar from blood to other tissues for energy. It is also used to stop the production of more sugar by the liver.
Although technology is not always necessary in health care, it helps doctors determine any problems we have in our bodies quicker, as well as cure them faster before it gets worse.
