Automatic tracking and registration of ultrasound probe using optical shape sensing without tip fixation
First Claim
1. A registration device, comprising:
- an attachment piece configured to conform with and couple to an imaging probe; and
a pathway formed in or on the attachment piece and being configured to receive an optical shape sensing device such that the optical shape sensing device can free float to permit longitudinal twisting within the pathway, the pathway including a distinctive geometry for shaping the optical shape sensing device such that the distinctive geometry provides a template pattern within an image collected using the imaging probe to permit registration between imaging coordinates and optical shape sensing coordinates.

Abstract
A registration device includes an attachment piece (106) configured to conform with and attach to an imaging probe (102), in particular an internal or external ultrasound probe such as a TEE probe. A pathway (105) 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 (107) within an image collected using the imaging probe module to permit registration between imaging coordinates and OSS coordinates. A registration module (130) is configured to compare a stored shape template (121) with an image (134) including the template pattern to permit the registration (unique transformation).
