Abstract

An electromagnetic field quality assurance system employing: an electromagnetic field generator (10) for emitting an electromagnetic field (12), and one or more quality assurance electromagnetic sensors (11, 21, 31) for sensing the emission of an electromagnetic field (12) , 41, 50). The system also employs a quality assurance controller (74) for evaluating the quality of the sensed position of each quality assurance electromagnetic sensor (11, 21, 31, 41, 50) within the field of view of the electromagnetic field (12). The tracking quality of the derived electromagnetic field (12) is monitored. The electromagnetic field generator (10), ultrasound probe (20), ultrasound stepper (30) and / or patient table (40) may be equipped with quality assurance electromagnetic sensor(s) (11, 21, 31, 41 , 50).

Description

technical field [0001] The present invention generally relates to tracking the intensity of electromagnetic fields (“EMFs”) emitted for electromagnetic guidance during interventional procedures (e.g., transrectal biopsy, transperineal biopsy, low dose rate brachytherapy, and high dose rate brachytherapy). quality. The present invention specifically relates to assessing electromagnetic field ("EMF") inhomogeneity based on quality assurance electromagnetic sensor(s) within a field of view (ie, a calibrated tracking region of the EMF) monitoring the EMF. Background technique [0002] In brachytherapy procedures involving electromagnetic guidance, an electromagnetic field generated by an EMF generator is positioned close to an anatomical region of interest. Typical EMF generators have a limited field of view ("FOV") (eg, FOV of 50x50x50 cm for a typical brick EMF generator). The tracking accuracy of the EMF generator depends on the relative distance and position of each tracke...
