A system and method for visualizing a cannula trajectory. An embodiment of the present invention generally includes an ultrasound probe attached to a first camera and/or a second camera and a processing and display generating system that may be in signal communication with the ultrasound probe, the first camera, and/or the second camera. A user of the system scans tissue containing a target vein using the ultrasound probe and a cross-sectional image of the target vein may be displayed. The first camera records a first image of a cannula in a first direction and the second camera records a second image of the cannula in a second direction orthogonal to the first direction. The first and/or the second images may be processed by the processing and display generating system along with the relative positions of the ultrasound probe, the first camera, and/or the second camera to determine the trajectory of the cannula. A representation of the determined trajectory of the cannula may be then displayed on the ultrasound image.
