1. A medical procedure training system for simulating ultrasound, imaging and ultrasound-guided medical procedures, the system comprising:

  • a control device;

    a graphical interface connected to the control device providing a plurality of interface sections, wherein a first interface section displays a digital video and a second interface section displays a virtual anatomical model and a three-dimensional ultrasound probe model, wherein the digital video comprises actual images previously recorded by scanning a live subject as well as simulated images, the actual images including a depiction of a muscle layer, the simulated images being modified actual images, the simulated images removing the depiction of the muscle layer from the actual images, where the actual images and simulated images are correlated to a position of the three-dimensional ultrasound probe model relative to the virtual anatomical model; and

    a user input device connected to the control device, the user input device comprising a motion sensor, the motion sensor detecting a position of the input device and a pointing direction of the input device,wherein, the graphical interface displays dynamic actual and simulated images corresponding to signals provided by the user input device, the signals corresponding to a spatial orientation, of the three-dimensional ultrasound probe model in relation to an area of examination of the virtual anatomical model, as determined from the position of the input device and the pointing direction of the input device, andwherein the system is configured to simulate ultrasound imaging and ultrasound-guided medical procedures through system feedback.
