Ultrasonic biomedical technology; marketing versus clinical reality.
Clinical ultrasound imaging is the most frequently used imaging modality in the world accounting for almost 25% of all imaging studies performed. Hence, manufacturers of commercial ultrasound equipment are committing significant engineering resources to advance the technology behind the modality and to improve the diagnostic capabilities of ultrasound imaging. Consequently, new imaging technologies are constantly being introduced to the market under a host of different trademarked names. Hence, this paper will review many of the recent advances in ultrasound imaging and try to differentiate between developments aimed at marketing and those providing real clinical improvements. In particular, we will describe the technologies behind concepts such as coded ultrasound imaging, real time spatial compounding, tissue harmonic imaging, extended field of view imaging as well as 3D and 4D (i.e., real time 3D) imaging. Some of the latest advances in blood flow imaging e.g., B-flow, advanced dynamic flow (ADF) and automatic optimization methods will also be described.
