EKG MACHINES

About the ultrasound machines Ultrasound or ultrasonography is a highly sophisticated method of medical imaging that uses high frequency sound waves and their echoes to create image of the objects on a visual monitor. This technique is similar to the echo sounders used by bats, whales and dolphins, as well as SONAR probes used by submarines. A basic ultrasound system contains following parts: 1. A sensory transducer probe that sends and receives sound waves. 2. A Central Processing Unit also known as CPU to calculate the signals sent and received and to provide necessary commands to the transducer, 3. Transducer pulse control units to control amplitude, frequency and duration of the pulses 4. A display monitor that shows the image 5. Keyboard to key in the necessary inputs 6. Data storage external device to help you store data in any format 7. A printer to help you print the image The transducer probe is the most important part of this machine. It has the capacity to create waves and receive those bounced waves. It produces sound waves by a principle called Peizoelectric effect. Many piezoelectric crystals change their rapidly when induced with electricity. These cause vibrations which eventually travel outwards towards the transducer surface. The electric current can be used to send and receive sound waves. This transducer also has a shock absorbing material which can absorb reflections from the probe. A transducer item comes in many shapes and forms, and its shape determines its field of view, and the frequency of emitted sound waves determines how deep the sound waves penetrate and the resolution of the image. There are multiple transducer probes to help you take sensitive readings. In addition to normal probes there are probes which can be inserted inside vagina, rectum and esophagus to check the inner details. The central processing unit is the heart of the whole system and this takes care of all calculating part of the operation. The CPU sends electrical currents to the transducer probe to emit sound waves, and also receives the electrical pulses from the probes that were created from the returning echoes. The transducer pulse controls allow the ultrasonographer, to set and change the frequency and duration of the ultrasound pulses, as well as the scan mode of the machine.
