Dynamic resource reconfiguration for patient interface module (PIM) in intraluminal medical ultrasound imaging

An intravascular ultrasound (IVUS) imaging system, comprising:

• a coronary IVUS imaging catheter comprising:
• a first flexible elongate member configured to be positioned inside a coronary vessel;
• and
• a first array of ultrasound transducers distributed a circumference of the first flexible elongate member;
• and
• a patient interface module (PIM) comprising a field programmable gate array (FPGA), wherein the PIM is configured for communication with:
• the coronary IVUS imaging catheter;
• and
• a peripheral IVUS imaging catheter comprising:
• a second flexible elongate member configured to be positioned inside a peripheral vessel;
• and
• a second array of ultrasound transducers distributed a circumference of the second flexible elongate member,
• wherein the FPGA itself is configured to operate as a trigger signal generator,
• wherein, when the FPGA operates as the trigger signal generator for the coronary IVUS imaging catheter, the FPGA is configured to generate a first trigger signal to cause the first array of ultrasound transducers to emit ultrasound waves with a first energy level for a first field of view in a circumferential image of the coronary vessel,
• wherein, when the FPGA operates as the trigger signal generator for the peripheral IVUS imaging catheter, the FPGA is configured to generate a different, second trigger signal to cause the second array of ultrasound transducers to emit ultrasound waves with a second energy level for a second field of view in a circumferential image of the peripheral vessel,
• wherein the peripheral vessel is larger than the coronary vessel, the second energy level is larger than the first energy level, and the second field of view is larger than the first field of view.
