ultrasound machine and patientThe Ultrasonography machine is a tool used in medical imaging techniques to help visualize muscles, tendons and other internal organs. Ultrasounds, as the name suggests, are high frequency sound waves that get reflected off the internal tissues of our body. One can evaluate their size, structure and any other anomalies if present based on the images an ultrasound machine produces.

The basic ultrasound machine is made up of a Transducer probe which makes the sound waves and receives the echoes. This is what the doctor applies to your tummy during pregnancy to evaluate the condition of the fetus. The other part is the Central processing unit (CPU) which is the brain of the machine and does all the calculations. The machine allows a specially trained sinologist to set and adjust the frequency and span of ultrasound pulses. A black and white display screen shows the images from the ultrasound data. The sound waves that get strongly reflected off from solid structures like bones and stones are visible as a black shadow on the screen while the soft tissues like muscles, blood vessels cast grayish white shadows. Ultrasound builds images that are exactly the opposite of those produced by an X-ray.

Ultrasonography has long been used to evaluate various organs like the liver, uterus as well as growing fetuses, blood vessels, glands etc. Sonography of joints and soft tissues of musculoskeletal system is gaining momentum recently in the fields of rheumatology, sports injury etc. The frequency range of the ultrasound waves used for diagnostic purposes cannot penetrate the bone and are strongly reflected off from the bony surfaces. Due to this ability to view the bony surfaces valuable diagnostic information can be obtained using this machine when assessing fractures, bony irregularities like growths (exostoses), erosions of bone (osteolytic lesions) and osteoarthritis (osteophytes).

Bone tumors can be assessed using Doppler settings in the machine helping assess the blood flow through a tumor. Stress fractures that are very minute when seen on a radiograph can be easily detected on an ultrasound. Ultrasound helps in diagnosing and monitoring rheumatic diseases.

The beauty of the ultrasound machine lies in its non-invasive diagnostic capacity that allows access to precise information, immediately and at cheaper costs compared to tests like CT or MRI scans. Our in-house ultrasound machine will speed up the diagnostic process and treatment by saving you unnecessary trips to a diagnostic center, especially where children or the elderly are concerned.

These sound waves will ensure rapidly that your bones and your health are safe and sound!
