MUBI Research Platform: Recent Advances and New Developments

The Multi-Modal Ultrasound Breast Imaging platform (MUBI) is a joint development of the Spanish National Research Council (CSIC) and the Complutense University of Madrid (UCM). It is composed of a ring of 16 transducers with 128 elements each, with a diameter of 22 cm, and working with a central frequency of 3.2 MHz. The total number of elements is 2048, and the electronic system can operate in single-element emission-reception or phased-array modes. It is intended to be a flexible platform for multi-modal ultrasound imaging research, combining reflection, transmission, and elasticity imaging, mainly oriented to breast diagnosis. In this work, research advances on the system are presented: Development of a fully operational prototype to be used with patients, design and manufacturing of calibration and anthropomorphic phantoms and design of an elastography device based on a waveform generator controlled vibrator. The work describes the design and laboratory preliminary tests of the new system components.
