From ESAOTE S.p.A.;
'The 260 Corvus is perfectly suited for multiple applications in black & white ultrasound. The digital console system is standard equipped with three probe connectors for a choice of various linear, convex, annular and annular phased array transducers. The 260 Corvus can be fully integrated into a digital hospital network (PACS) using the optional DICOM® compatible ImageLab™ module.'

From Fukuda Denshi Co., Ltd.;
'Phased array probes made available for High resolution imaging of full cardiovascular examinations.
By adding Linear and Convex probes, the examination areas are extended to Abdominal and OB/GYN applications.
B-mode (1, 2 displays), M, and B/M-modes can be individually shown.
Optional Doppler unit available for observation of Blood flow information in pulsed and continuous wave Doppler.
Portable with IP (Image Processing), Full Keyboard, and track ball are standard.'

In contrast enhanced ultrasound, the focus is the point at which maximum bubble destruction occur.
The transmit focus is the region on the axis of an ultrasound beam where the width of the beam has a minimum value. All waves crossing the focus are in phase in relation to the transducer surface or to the electronic summing point of an electronically focused array.

The dimension of the ultrasound beam and the transducer array are the origin of grating-lobe artifacts (also called side lobe artifact). Grating lobes as side lobes are off-axis secondary ultrasound beams projecting at predictable angles to the main lobe. Side lobes are too small to produce important artifacts.
