Accurate guidance and placement of the needle tip at the target point is one of the important processes in needle-guided interventions. Today, the dominant method is the use of a C-arm device and X-Ray imaging, which exposes the patient, especially the physician and technicians, to a high radiation dose. Recently, many efforts have been made to use the ultrasound modality in these interventions, which, despite its numerous advantages, is still of limited use for some reasons. One of these reasons has been the difficulty of simultaneously tracking the target areas and the needle tip in in-plane and especially out-of-plane images. In this project, the goal is to design and implement a system based on an array of magnetic sensors to track a magnetic marker attached to the tip of the instrument or to use the ferromagnetic effect of metals and track a magnetized needle. To do this, we use perceptron neural networks as a well-known and efficient method for solving regression and classification problems.
