Definition of product requirements of a MR compatible bone biopsy system using workflow analysis

Image-guided needle biopsy is a standard method in cancer diagnostic for tumor staging [1, 2]. As guiding modality computer tomography (CT), ultrasound, X-ray or magnetic resonant imaging (MRI) is being used for instrument navigation. For MRI guided procedures a MRI compatible needle in combination with a driller is required. To define the specification of such a system workflow analysis was applied as part of the product development cycle [3].
