Abstract:
A medical device for a medical imaging system, the medical device comprising:an elongate body adapted to be inserted into a patient's body; a drive shaft being substantially within the elongate body and having a proximal end portion and a distal end portion, the proximal end portion adapted to communicate with the medical imaging system; a first imaging device adapted to transmit energy and has a center frequency, the first imaging device being mounted on or near the distal end portion of the drive shaft; a second imaging device adapted to receive a reflection of the energy transmitted by the first imaging device, the second imaging device being mounted on or near the distal end portion of the drive shaft at a distance from the first imaging device and having a center frequency substantially equal to a fundamental harmonic of the energy transmitted by the first imaging device; and a third imaging device adapted to receive a reflection of the energy transmitted by the first imaging device, the third imaging device being mounted on or near the distal end portion of the drive shaft at a distance from the first imaging device and having a center frequency substantially equal to a second harmonic of the energy transmitted by the first imaging device.
