摘要：
A catheter-based imaging apparatus comprises a catheter having a proximal end and a distal end. An optical emitter is configured to emit optical excitation signals from a distal portion of the catheter. One or more ultrasound transducers are configured for: (a) transmission of acoustic excitation signals from the distal portion of the catheter； and (b) detection of ultrasound response signals from an object of interest at or near to the distal portion of the catheter at frequencies which include a lower receive frequency at least as low as 10 MHz and a higher receive frequency at least as high as 35 MHz. The one or more ultrasound transducers are thereby configured to detect response signals comprising photoacoustic response signals from the object of interest at the lower receive frequency and high resolution imaging signals from the object of interest at the higher receive frequency.
