The invention provides systems, methods, and instrumentation for aiding the performance of an image guided procedure of the anatomy of a patient such as, for example, the prostate. The invention includes a plurality of lumens therein and a balloon portion or other fixating portion. In some embodiments, the catheter includes a lumen for introducing a contrast agent visible to an imaging modality external to the anatomy of the patient. Image space data of the catheter within the anatomy of the patient may be obtained using the imaging modality. The catheter also includes at least a lumen for inserting a registration device for obtaining patient space data regarding the anatomy of the patient. Other lumens and/or other elements visible to the imaging modality may be used. The image space data may be registered to the patient space data for use during an image guided procedure to the anatomy of the patient.
