Diagnostic imaging utilizes a variety of procedures that assist in diagnosing disease and illness. The most common type includes magnetic resonance imaging and x-rays. In some cases other technology besides radio waves may be used, including sonography, also known as ultrasonography. This type of technology utilizes sound waves in order to produce an image that can be assessed to provide a diagnosis of different medical conditions. Sonography is frequently thought of in connection with obstetrics but it can be used in a variety of other applications.
Medical Sonographer Job Responsibilities
Sonographers utilize special equipment in order to direct high frequently sound waves into areas of the body. By operating special equipment, reflected echoes can be collected in order to form an image that can then be videotaped and even transmitted or photographed for further interpretation and diagnosis by a doctor. Sonographers may explain the procedure to patients as well as record medical histories that might be relevant to the condition. They are responsible for choosing the correct equipment settings and directing the patient to move into positions that will offer the best view. A transducer is used to transmit sound waves in a rectangle or cone shaped beam. Techniques can vary according to the area that is being examined. Sonographers also use a special gel that is applied to the skin to assist in the transmission of sound waves.
During the scan, sonographers will look for cues that can contrast unhealthy areas from healthy areas. They will then determine whether the images are satisfactory enough for the purposes of diagnosis and choose which images will be stored to show to the doctor. Sonographers may also take measurements as well as calculate values and analyze the results of the findings for doctors.
Along with working with patients, sonographers also usually take medical records and maintain and adjust equipment. Other job duties may include evaluating the purchase of equipment, preparing work schedules and managing a diagnostic or sonography department.
In some cases a sonographer may choose to specialize in abdominal sonography, obstetric and gynecology sonography, neurosonography or breast sonography. Other areas of specialty include cardiac and vascular sonography. Obstetric and gynecologic sonographers specifically specialize in imaging involving the female reproductive system, including examining a fetus in order to track the health and growth of the baby during pregnancy. Abdominal sonographers specialize in inspecting the abdominal cavity in order to diagnose as well as treat conditions that might involve the kidneys, spleen, liver, pancreas, gallbladder and male reproductive system. Neurosonographers specialize in the nervous system, which includes the brain. Breast sonographers track tumors in the breasts as well as monitor the supply of blood.
Sonographers usually work in healthcare facilities. They may need to be on their feet for long periods of time and may also need to turn or lift patients who are disabled. In some cases, sonographers may need to travel to other healthcare facilities. Most sonographers work approximately 40 hours per week. Weekend and evening work may be necessary if on call.
