The Aplio i900 is the top of line product from Canon. Canon has achieved a great reputation in the ultrasound industry by maintaining high standards in both image quality and functionality within Radiology. However, due to the lack of 4D matrix transducers and interventional cardiology options, Canon has revealed its limitation in cardiovascular applications. It seems that with the release of these 4D options with the Aplio i900, Canon enables to knock down the premium cardiovascular market; however, its reliability of 4D solutions and the quality of 4D images are not yet proven clinically. It is expected that more clinical testimonials and papers will be available in the near future.
