Objectives and Approach

The main objective is to develop a prototype of bidimensional ultrasound imaging probe (2D-UIP), built with technologies compatible to industrial manufacturing, which demonstrates the image quality improvement brought by the two dimensional electronic focusing. The design will be usable for clinical evaluation with state of the art existing ultrasound imaging systems. The proposed probe will give an image enhancement up to the level of a dedicated designed annular array from a mechanical sector scanning probe. Compared to the annular array technique, the electronic scan with 2D array technique has the advantage in offering the possibility for real-time multi-imaging mode (eg 2D/Mmode, 2D/doppler mode, 2D/CF mode), which is impossible to do with an annular array.

The main quantified objective at the level of the overall image quality is to obtain across the whole useful depth of field the same contrast (directly related to the transverse spatial resolution) as at the exact focus point of the lens. This objective specification will dictate the 2D-UIP definition.

In order to achieve the main objective, secondary objectives are related to key components of the 2D-UIP:

These three components are spin-offs that will be reused for new products. The acoustical 2D array is a key component for future 3D imaging systems and for advanced conventional 2D imaging systems with a very large number of channels, already proposed by several system manufacturers. The front end and beam-forming ASICs are also key component for large scale integration of the new systems generations.
