A probe for detecting at least one property of a chronic total occlusion in a lumen. The probe includes an elongated member having a distal end configured to be inserted into the lumen, and an ultrasound transducer mounted at the distal end of the elongated member. The ultrasound transducer is configured to emit an ultrasonic signal and to receive a reflected signal from the chronic total occlusion. The probe also includes a processor configured to receive the reflected signal from the ultrasound transducer and convert the reflected signal to at least one property of the chronic total occlusion.
