The EUB-525 is a mid-size ultrasound system with a full feature set. Capable of B-mode, M-mode, Doppler, color flow and color angiography it performs a variety of tasks in a simple and straightforward fashion. This system produces high quality images with excellent clarity and detail.

(AALs) Acoustically active lipospheres and ultrasound are under development to deliver bioactive molecules to the vascular endothelium. The AALs are similar to both ultrasound contrast agents and drug-delivering liposomes. They can carry bioactive substances using biologically inert shells and deliver those substances when disrupted by ultrasound.
The lipospheres consist of a small gas microbubble surrounded by a thick oil shell and are enclosed by an outermost lipid layer. The gas bubble contained in these vehicles makes them acoustically active, similar to ultrasound contrast agents. Acoustically active lipospheres can be nondestructively deflected using ultrasound radiation force, and fragmented with high intensity ultrasound pulses. Their lipid-oil complex can carry bioactive substances at high concentrations. An optimized sequence of ultrasound pulses can deflect the AALs toward a vessel wall then disrupt them, painting their contents across the vascular endothelium.

(CAI) Color amplitude imaging shows the amplitude of the Doppler signal from moving blood flow. CAI is an ultrasound technique with increased dynamic range and flow sensitivity. The sensitivity of Doppler ultrasound increases markedly in conjunction with the use of vascular contrast agents.
