SoftVue is a true innovation and as the first of its kind, it introduces a new way of imaging the breast through the sophisticated capture and treatment of sound signals. SoftVue has received FDA clearance for diagnostic imaging purposes and is not intended for use as a replacement for screening mammography.
During the SoftVue procedure, the technologist assists the patient to lie prone with her breast suspended in a warm water reservoir. Centering the breast is performed accurately and simply, aided by real-time camera guidance. A uniquely-designed comfort-pad and soft membrane layer are integrated with the table surface for patient comfort during the exam.
By introducing a singularly unique approach in transducer design, SoftVue incorporates over 2000 transducer elements within a uniform ring configuration. Multi-parameter sound characteristics of reflection, sound speed, and attenuation are collected and retained in a circumferential, tomographic series analyzed by proprietary algorithms, providing volumetric measurements.
Traditional hand-held ultrasound and automated breast ultrasound systems obtain only reflected echoes returning in the direction of the linear transducer. By contrast, SoftVue captures reflection echoes from all directions around the breast and gathers transmitted signals coming through the breast, something no other ultrasound system, currently available, can do.
Ongoing research for future SoftVue applications includes evaluating the elastic properties of tumors and applying proprietary curved ray tomography to generate images based on through-transmission data. Our vision for SoftVue moves beyond anything that has been introduced before by combining the sound properties of reflection, speed, and attenuation.
