Optimizing circular ring arrays for forward-looking IVUS imaging
(IEEE-Inst Electrical Electronics Engineers Inc, 2011-12)
Forward-looking (FL) catheter-based imaging systems are highly desirable for guiding interventions in intravascular ultrasound (IVUS) applications. One of the main challenges of array-based FL-IVUS systems is the large ...
Monolithic CMUT-on-CMOS integration for intravascular ultrasound applications
(IEEE-INST Electrical Electronics Engineers Inc, 2011-12)
One of the most important promises of capacitive micromachined ultrasonic transducer (CMUT) technology is integration with electronics. This approach is required to minimize the parasitic capacitances in the receive mode, ...
An Analog beamformer for integrated high-frequency medical ultrasound imaging
(IEEE, 2011)
We designed and fabricated a dynamic receive beamforming integrated circuit (IC) in 0.35-mu m CMOS technology. This beamformer is suitable for integration with an ultrasound annular array for high-frequency (30-50 MHz) ...
Experimental study of dual-ring CMUT array optimization for forward-looking IVUS
(IEEE, 2011)
Forward-looking (FL) catheters have guiding and volumetric imaging capacities which are highly desirable for IVUS applications. Large channel and firing counts have to be reduced to enable 3-D real-time imaging and simplify ...
