Atlas of Musculoskeletal Ultrasound Anatomy is aimed at the radiology trainee, the practising radiologist with an interest in musculoskeletal work
The images in the current text were achieved using an ATL HDI 5000 SonoCT ultrasound system (Advanced Technology Laboratories, Bothwell, WA) coupled with an L12–5 MHz footprint linear array transducer. A stand-off pad was not used, but liberal amounts of coupling gel was applied.
Most of the images displayed were obtained using ATL’s patented SonoCT real-time compound imaging technology. This technology is distinct from conventional ultrasound in that it obtains images from multiple lines of sight. In real-time compounding, ultrasound beams are steered from up to nine lines of sight and are combined into a single image at real-time frame rates. This allows all structures to be scanned at a plane that is at or close to 90° to one or more of the scan lines. It is distinct from other compounding methods, in that it uses computed transmit-and-receive functions to form a compound image in real time. This technology can dramatically suppress or eliminate many routine problems that degrade ultrasound images, such as noise, speckle, clutter and image artefacts. In addition, contrast resolution is enhanced improving diagnostic confidence.
Recently, ATL have introduced SonoCT Imaging achieving a breakthrough in panoramic image quality. ATL uses patented pattern recognition technology, instead of matching pixels along the edge of an image to generate a panoramic appearance. Panoramic SonoCT relies on processing tissue patterns captured from a region of interest. This real-time pattern recognition method makes it easier and faster to perform panoramic scanning because it is less dependent on the user maintaining a steady and smooth sweep. It also enables the user to easily reverse direction without restarting a panoramic scan
