Siemens Acuson Sequoia Ultrasound C256 Repair

Siemens's Acuson Sequoia C256 is an ultrasound. Ultrasounds are used to diagnose patients by creating an image of internal body structures such as blood vessels, muscles, and internal organs to measure some sort of characteristic or to generate an informative audible sound. These machines date back to 1880, where piezoelectricity was discovered by a French physicist, but was only ever applied to the human body for medical purposes in the late 1940s. From there, the first commercial hand-held scanner was invented in 1963 which made ultrasound generally available for medical use, and now today there is a wide range of ultrasounds such as the Acuson Sequoia C256.

The Acuson Sequoia C256 was known at the time for a dramatic improvement in dynamic range, spatial resolution, and frame rates that allowed for higher quality imaging. On top of that, the machine was user-friendly and ergonomic to streamline workflow.

Though Siemens has now discontinued the product, they offer upgrades into the Acuson Origin on their site.

Other than the transducers, the Acuson Sequoia C256 consists of one part, with the DIMAQ workstation being completely embedded into the machine for easy access. To the sides of the machine are racks to hold any transducers that will be used. The base unit has a height of 148 cm, a length of 66 cm, and a weight of 4.06 lbs.

There are a variety of transducers that can be used with the machine, but one it features is the 3V2c transducer which can be stored on either sides of the machine, and the cord connected below the workstation. The transducer is a white cylindrical piece that has a wider tip at the end for echocardiography and more. The transducer also has a frequency bandwidth of 4-2 MHz.
