Abstract

The magneto-acoustography is a hybrid imaging technique that excites the middle marked with (micro or nano) particles with a magnetic force generated by an external magnetic coil. Then the disturbance caused to the environment is evaluated from the ultrasonic echoes (RF maps) captured with an ultrasonic transducer, which are processed by computer algorithms and generate an image of the medium under study, as well as possible obtain viscoelastic parameters through the middle of metrics elastography. The ultrasound equipment Sonix RP, Ultrasonix, has a search interface that enables the development of software applications written in C/C + + and Qt, for acquisition and processing maps of RF, this environment contains a development kit software DSK, with which it is possible to combine high-level computer processing parameters and processing low-level, and thereby obtain greater flexibility in acquisition and processing of PRs. The project focuses on developing software based on the DSK Sonix RP and its use as an auxiliary tool in the development and refinement of innovative techniques such as ultrasound, for example, this new hybrid technique that uses magnetic fields to promote a mechanical disturbance of the environment marked with magnetic particles and evaluates the visco-elasticity of tissue by acoustic measurements. This technique is called magneto-acoustography.(AU)
