Abstract
An ultrasound system and method for intravascular imaging is disclosed. The ultrasound system includes an intravascular catheter with an ultrasound transducer array, a transmit beamformer, a receive beamformer, and an image generator. The intravascular catheter has an elongated body made for insertion into a blood vessel and connected to a catheter handle. The catheter includes a catheter core located inside a steerable guide sheath, both having a proximal part and a distal part. The catheter includes an articulation region connected to a positioning device for positioning the transducer array to have a selected orientation relative to an examined tissue region. For each orientation of the transducer array, the transmit and receive beamformers acquire ultrasound data over an image plane of the examined tissue region. The catheter core is connected to a rotation device constructed and arranged to rotate, or oscillate over an angular range, the transducer array that acquires ultrasound data over a multiplicity of image planes. The image generator is constructed to form a selected tissue image based on the acquired ultrasound data.
