Abstract
Systems, devices, and methods for intraluminal ultrasound imaging are provided. An intraluminal ultrasound imaging system may include a patient interface module (PIM) in communication with an intraluminal device comprising an ultrasound imaging component and positioned within a body lumen of a patient. The PIM may receive ultrasound echo signals from the intraluminal device, transmit the ultrasound echo signals along a differential signal path, and digitize the ultrasound echo signals. The PIM may transmit the ultrasound wirelessly to a processing system. The PIM may be powered with a wireless charging system, such as an inductive charging system.
Claims20
A sensing system, comprising:
- a patient interface module (PIM) communicatively disposed between a processing system and a sensing device configured to be positioned within a body of a patient, the PIM comprising a transmitter, an analog to digital converter (ADC), a communication device, and a power source,
- wherein, in an operating mode, the power source is configured to power the PIM to transmit and receive signals associated with at least one of the sensing device or the processing system,
- wherein, in a charging mode, the power source is configured to be recharged by a wireless charging system,
- wherein, in the operating mode, the PIM is configured to:
- transmit, with the transmitter, a first signal to the sensing device;
- receive a measurement signal associated with the first signal from the sensing device such that the sensing device obtains the measurement signal from the body of the patient and the PIM is different than the sensing device;
- digitize the measurement signal with the ADC;
- and
- transmit the digitized measurement signal to the processing system wirelessly via the communication device,
- wherein, in the charging mode, the PIM is prevented from transmitting or receiving the signals such that the sensing device and the processing system do not operate with the PIM while the PIM is in the charging mode,
- wherein the sensing device is an intraluminal ultrasound device configured to be positioned within a body lumen of the patient, and
- wherein the measurement signal is ultrasound echo signal.
A sensing method, comprising:
- providing a patient interface module (PIM) communicatively disposed between a sensing device and a processing system, wherein the PIM comprises a power source,
- in an operating mode:
- powering, using the power source, the PIM to transmit and receive signals associated with at least one of the sensing device or the processing system,
- controlling, using a transmitter of the PIM, the sensing device by transmitting a first signal to the sensing device when positioned within a body of a patient;
- receiving, with PIM, a measurement signal associated with the first signal from the sensing device such that the sensing device obtains the measurement signal from the body of the patient and the PIM is different than the sensing device;
- digitizing the measurement signal with an analog to digital converter (ADC) in the PIM;
- and
- transmitting the digitized measurement signal to the processing system via a wireless communication device;
- and
- in a charging mode:
- recharging the power source using a wireless charging system;
- and
- preventing the PIM from transmitting or receiving the signals such that the sensing device and the processing system do not operate with the PIM while the PIM is in the charging mode,
- wherein the sensing device is an intraluminal ultrasound device configured to be positioned within a body lumen of the patient, and
- wherein the measurement signal is ultrasound echo signal.
