Disclosed herein are systems and methods for providing real-time monitoring of a probe within a target zone. An apparatus for tracking the probe comprises a transducer assembly comprising a two-dimensional array of transducer elements. The two-dimensional array comprises a plurality of transverse arrays and a plurality of longitudinal arrays. The monitoring system further comprises a processor configured to activate and receive data from at least one transverse array extending along a transverse axis that is transverse to the target zone and to a direction of travel of the probe, and two or more longitudinal arrays extending along longitudinal axes that are transverse to the transverse axis. The two or more longitudinal arrays may be activated sequentially in a programmed sequence. Based on the data, the processor can determine the position of the probe within the target zone, and display the probe on a transverse cross-section view of the target zone via a software-generated special effect.
