An intervention system employs an optical shape sensing tool () (e.g., a brachytherapy needle having embedded optical fiber(s)) and a grid () for guiding an insertion of the optical shape sensing tool () into an anatomical region relative to a grid coordinate system. The intervention system further employs a registration controller () for reconstructing a segment or an entirety of a shape of the optical shape sensing tool () relative to a needle coordinate system, and for registering the needle coordinate system to the grid coordinate system as a function of a reconstructed segment/entire shape of the optical shape sensing tool () relative to the grid () (i.e., reconstruction of a segment/entire shape of the OSS needle inserted into/through the grid serving as a basis for the grid/needle coordinate system registration).

Registration of optical shape sensing tool

A registration device includes an attachment piece () configured to conform with and attach to an imaging probe (), in particular an internal or external ultrasound probe such as a TEE probe. A pathway () formed in or on the attachment piece is configured to receive an optical shape sensing device (OSS fiber) such that the optical shape sensing device can free float (no tip fixation) to permit longitudinal twisting within the pathway. The pathway includes a distinctive geometry for shaping the OSS device such that the distinctive geometry provides a template pattern () within an image collected using the imaging probe module to permit registration between imaging coordinates and OSS coordinates. A registration module () is configured to compare a stored shape template () with an image () including the template pattern to permit the registration (unique transformation).
