Specifications for this system will be available soon.

The perfect image quality is dependent on some assumptions of the propagation of ultrasound waves in tissues after generating in an imaging system. These assumptions are important for the developing of optimal ultrasound imaging systems.
A lot of steps can be taken to prevent artifacts and to improve image quality, for example beamforming is used to focus the ultrasound beam, and contrast agents decrease the reflectivity of the undesired interfaces or increase the backscattered echoes from the desired regions.

Imagent® is an injectable suspension for intravenous administration during a sonogram. This diagnostic contrast agent for enhancement of ultrasound images contains perflexane lipid microspheres. Imagent® US is indicated in the assessment of heart function and perfusion, as well as the detection of tumors and blood flow abnormalities by using gray scale, color Doppler, and harmonic ultrasound imaging techniques.
During the course of its development, the brand name for this product has changed from Imagent to Imavist (between August 2000 and March 2002) back to Imagent. The manufacturer's 06/03/02 press release announcing FDA approval refers to the product as 'Imagent (formerly Imavist),' and the approval notice and monograph posted at the FDA site refers to the product as Imagent.

Founded in 1991, ImaRx Pharmaceutical Corp. designs, develops and markets pharmaceuticals for medical imaging (MRI, ultrasound and computed tomography) for the radiological imaging industry.
ImaRx Pharmaceutical Corp., announced 1999 that it has been acquired by E.I DuPont de Nemours & Co., Inc. The terms of the acquisition provide a royalty-free licensing arrangement with a newly-formed company, ImaRx LLC ('LLC'), to pursue and develop new products and technologies for drug and gene delivery independent from DuPont. Yamanouchi Pharmaceutical Co. Ltd., ImaRx' licensee for Asian territories for this product, will continue to develop the product in Asia as DuPont's licensee. ImaRx LLC will have ownership of all other targeted and therapeutic products previously owned by ImaRx, including imaging products outside of diagnostic ultrasound imaging and two other imaging products, SonoRx® and LumenHance®, which are both FDA approved and licensed to BRACCO Diagnostics.
