Multiple sensor catheter assembly

An ultrasound imaging device comprising:

• an imaging assembly for minimally invasive insertion inside a patient body, the imaging assembly including:
• an ultrasound transducer array having a plurality of transducer array elements;
• and
• an integrated circuit operatively connected to the ultrasound transducer array inside the imaging assembly, the integrated circuit including a memory, the integrated circuit including the memory is positioned on a flexible substrate that forms a part of a distal tip, the distal tip having a length between 5 mm and 30 mm, the memory being programmed to store:
• a transmit-receive sequence that includes transmitting an ultrasound signal on one or more than one transducer array element of the plurality of transducer array elements, and receiving ultrasound signals on the one or the more than one transducer array element of the plurality of transducer array elements;
• wherein the integrated circuit is operatively connected on a receive line to the plurality of transducer array elements;
• wherein the memory stores operational codes that optimize a sub-aperture of the ultrasound transducer array by programming the integrated circuit to decrease a number of transmit-receive elements within the sub-aperture to minimize acquisition time and motion artifacts, or to increase the number of transmit-receive elements within the sub-aperture to increase resolution and depth of penetration;
• wherein the memory includes a static random-access memory that dynamically stores the transmit-receive sequence and operational codes to configure the integrated circuit to support an ultrasound scanning modality;
• and
• wherein the integrated circuit is configured to multiplex output signals from one or more pressure sensors located on the imaging assembly onto a transmission line connected to the integrated circuit and that receives the ultrasound signals from the integrated circuit.
