What are the different types of diagnostic equipment?
Before the arrival of modern medical technology, it was often difficult for doctors to precisely diagnose conditions that could not be directly observed or derived from symptoms. In today's hospitals, medical staff have luxury diagnostic equipment that can be used to view internal structures, heart monitoring and brain activity and analysis of organ functioning. There are many different types of diagnostic devices, including magnetic resonance (MRI) machines, computed tomography (CT), electrocardiograph (ECG) and ultrasound monitors and monitors and cancer and cancer and cancer tumors and cancerous tumors. The machine itself resembles a large tube where the patient's body or whole body can be inserted for testing. When it is turned on, the magnetic field surrounds the body, causing temporarily alignment of hydrogen protons in the cells. Another magnetic field agitates The protons and allows them to return to normal. The computer analyzes proton activity and the time that takes them to settle down to createIf a highly accurate representation that can clearly show the presence of any irregularity in the tissue.
CT scanners work similarly to MRI machines, although they use radiation instead of electromagnets to create images. The CT machine emits multiple X -rays from different directions and creates an accurate two -dimensional computer image. Doctors can print pictures and analyze the contrast to determine tumors, brain injuries and bone fractures. Another very similar piece of diagnostic equipment known as the scanner of positron emission tomography is often used in conjunction with a CT machine to portray three -dimensional images.
ECG is a very valuable piece of diagnostic equipment because it allows a doctor to accurately analyze the functioning of the heart. The electrodes are connected to the machine by means of small wires and connected to the chest, arm or patient's feet. Electrodes record and measure electrical activity in the body to bring backThey were in real -time cardiac activity. Computer print, known as electrocardiogram, may indicate irregular heart rhythms, muscle weakness and tissue damage.
Ultrasound technology allows experts to portray internal video in real time without the patient is subject to radiation or electromagnetic field. High -frequency sound waves are sent by the body area where they reflect and send back to an ultrasound device. The result is accurate depiction of organs, muscles and joints. Prenatal care specialists often use ultrasonic scanning to view fruits and control of irregularities.
Today, dozens of other important diagnostic facilities are used, and medical scientists are constantly improving to currunt technology. The aim of many scientists is to create machines that are cheap, portable and relatively easy to use. Innovation will allow doctors to make even more accurate and immediate diagnoses.
