Description

Purpose: To evaluate a noninvasive navigation method employing a conventional diagnostic ultrasound system to safely advance a small-diameter probe through a blood vessel without prolonged x-ray exposure to the operator or physician. Subjects and Methods: We conducted a comparative study of navigation methods. The signal transmitted by a small diameter-probe placed in a blood vessel and received by a conventional real-time ultrasound system indicated the position of the probe. Results and Discussion: We designed and built the experimental probe and set up the experiment. The optimum shape of the conic reflector used to transmit broad-beam ultrasound was an 80-degree cone 1.0mm in diameter. Indicated probe position in the basic navigation experiments was less than ±1.5mm from its actual position. Conclusions: Results confirmed the performance of a two-dimensional ultrasound system and suggested its potential value.
