The discovery of X-rays has brought a revolution in the field of medicine as it allows physicians and scientists to see through a living body. Currently, modern medicine is going through an important change due to the advent of nuclear medicine - one of the most effective forms of treatment available today. Along with molecular imaging, it helps to see the functioning of a body and what’s happening at the cellular and molecular level, thus helping to know the occurrence or progression of a disease, assess new drugs, improve the selection of therapy, track patient response to treatment, and more.

Nurse call systems are developed to alert nurses in case of a medical emergency or need for care. These systems are intended for patient-to-nurse communication. On pressing the alert button, a call light and an alert tone are initiated at the nurse's desk. These systems are also used to track a patient, particularly in assisted living or old age centers, or are used to designate an event, in case of ambulatory services. These systems reduce the response time by nurses and doctors, leading to a productive workflow.
