本发明题为"多模态图像的可变形配准"。本文所讨论的主题涉及术前磁共振成像(MRI)数据与术中超声(US)数据(例如，重建的图像或未重建的数据)的自动实时配准，诸如以促进外科手术引导或其他介入程序。在一个此类示例中，脑结构(或其他合适的解剖特征或结构)在术前超声数据和术中超声数据中自动分段。然后，在术前超声数据与术中超声数据之间应用解剖结构(例如，脑结构)引导的配准以说明成像的解剖结构的非线性变形。然后对与术前超声图像预先配准的MR图像给定同一非线性空间变换以将该MR图像与术中超声图像对准以提供外科手术引导。 The subject matter discussed herein relates to the automatic, real-time registration of pre-operative magnetic resonance imaging (MRI) data to intra-operative ultrasound (US) data (e.g., reconstructed images or unreconstructed data), such as to facilitate surgical guidance or other interventional procedures. In one such example, brain structures (or other suitable anatomic features or structures) are automatically segmented in pre-operative and intra-operative ultrasound data. Thereafter, anatomic structure (e.g., brain structure) guided registration is applied between pre-operative and intra-operative ultrasound data to account for non-linear deformation of the imaged anatomic structure. MR images that are pre-registered to pre-operative ultrasound images
