[Usefulness of ACUSON Freestyle (Siemens), Wireless Ultrasound System]
Abstract:
The ACUSON Freestyle, the world's first wireless ultrasound system, was released in April 2014. We assessed its usefulness, using it for central venous cannulation, spinal anesthesia, brachial plexus or obturator nerve block, and for the surgery of metastatic liver cancer as well as the spine. Generally, we could use it smoothly in all situations. Comparing with the conventional ultrasound system, the machine is big, heavy, with many buttons to operate. The main problem with the conventional ultrasound system is the wire connecting probe and the main system, which can interfere with procedures. With ACUSON Freestyle, we could perform the nerve block and the central venous cannulation more easily with little concern about contamination.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
