In some cases, because the frequency is low, it can used for abdominal studies as well.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. Typically obgyn studies are performed with abdominal transducers. 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. It is a device, usually electrical, or, in some cases, mechanical, that converts one type of energy to another. A transducer, or probe, is the main part of the ultrasound machine. The transducer sends ultrasound waves into the body and receives the echoes produced by the waves when it is placed on or over the body part being imaged. The most widely available type of 3D transducer is the mechanical transducer, which is low-cost and achieves state-of-the-art image quality, although it cannot produce images in real time. D transducers are matrix array transducers, which generate an ultrasound pulse diverging from the array in a pyramid shape and produce high-quality images in real time. This technology is used in obstetrics only for the evaluation of the fetal heart and adult echocardiography. Multiple transducers had to be purchased for different depths of studies. Modern state of the art transducers are designed to be capable of varying the frequency, depending on the depth necessary for a given ultrasound. They are usually older and slower, and have a shorter life expectancy. Typically, 3D4D transducers are mechanical and have a much larger footprint. Electrical transducers are faster, smaller, and last longer. Cardiac is typically the smallest; vascular ranges in size from 25mm to 50mm; abdominalcurved shape has a larger footprint, and transvaginal transducers are long and skinny with a small head. Transducers do lose quality when elements and crystals have been damaged. It is covered by a rubber arraylens, which can be worn away by over-zealous sterilization procedures and must be replaced or repaired. ![]()
