Absolute Medical carries an extensive selection of internal and external ultrasound probes and transducers, from the foremost manufacturers of ultrasound equipment, including Acuson, ATL, Diasonics, Eden, GE, HP, Kretz, Medison, Philips, and Shimadzu. These versatile diagnostic tools excel at determining the size, shape and consistency of soft tissues and organs without the risks associated with X-rays and CT scans. The uses of ultrasound are manifold: as screening tools throughout pregnancy; as diagnostic tools for conditions affecting organs or soft tissues; as real time imaging guidance during procedures such as biopsies; and for detection and treatment of soft tissue injuries. Internal probes are available for vaginal, rectal, and esophageal imaging. Imaging options include doppler, bone sonography, echocardiography, and can be rendered in flat 2D, static 3D, or moving 4D images.
Ultrasound Probes & Transducers Questions & Answers
First, there is the cardiac transducer, whose primary use is echocardiography. In some cases, because the frequency is low, it can used for abdominal studies as well.
Second, there is a vascular transducer, which is typically used for carotid arteries and veins, including those in the legs. It can also be used for the thyroid, needle-guided injections, and in some cases, when the frequency is high enough, for breast exams, as well. It is important to note that when using it for breast exams, it should not take the place of conventional mammography, but rather in conjunction with it.
Third, abdominal transducers are used in organs, such as kidney, liver, spleen, and stomach. Typically ob/gyn studies are performed with abdominal transducers.
Fourth, transvaginal transducers are used to perform studies on women at various stages of pregnancy, during every ultrasound..
Fifth, there is the endorectal transducer, which is typically used to check for rectal cancer. Urologists primarily use this transducer.
Last, the transesophageal echocardiography (TEE) transducer is used to evaluate cardiac studies by use of the echo transducer that produces the sound waves for TEE. The probe is attached to a thin tube that passes through your mouth, down your throat and into your esophagus. Because the esophagus is so close to the upper chambers of the heart, very clear images of those heart structures and valves can be obtained.
Modern day transducers are made of crystals which typically can last for 10-plus years. Transducers do lose quality when elements and crystals have been damaged. It is covered by a rubber array/lens, which can be worn away by over-zealous sterilization procedures and must be replaced or repaired. Usually this repair runs between $750 to $1000.
Mechanical transducers have a much shorter life expectancy and depending on the frequency of use can usually last 3 to 5 years before needing replacement.
