IPLAN

Intended Use:

iPlan's indications for use is to prepare and present patient and image data based on CT, MR, X-ray(Fluoro), including

* image preparation

* image fusion

* image segmentation

where the result is used for the creation of treatment plans for Stereotactic Surgery:

- Surgery Planning

The Surgery Planning is a tool for pre- and intraoperative stereotactic surgery planning based on stereotactic systems. Multiple graphical display functions and 3-dimensional views of anatomical structures offer effective and efficient means of presenting the anatomical data for diagnostic and surgical planning. Computer-graphic simulation in various views of a chosen probe path can help prevent probe intersections with unwanted, critical structures or vessels.

The surgeon can interactively change a probe path simulation through the image slices in the software with on-line calculation of the accompanying arc settings and graphical manipulation to aid in optimizing his approach.

- BrainMAP

The BrainMAP module is a tool, which defines two and three-dimensional information about anatomical structures of the human brain for pre- and intraoperative planning of stereotactic procedures. These contours are defined and described by Talairach/Tournoux and/or Schaltenbrand/Wahren based brain atlases.

The user is provided with information about the position of the various functional and anatomical areas of the brain. These positions of the structures have to be correlated with every patients brain data. The correlation is defined by a procedure defined by Talairach/Tournoux. Using their grid system to divide the brain in particular areas, the program will be able to provide matching data for different patient data. BrainMAP may be used alone or in conjunction with neurosurgery.

- Functional Planning

The Functional Planning is based on Surgery Planning, which gives two- and three dimensional online information of a stereotactical surgical instrument (electrodes) for a neurosurgical functional treatment using a stereotactic arc. The user is provided with information by numerical results and by various displays and reconstruction planes based on patient images (CT, MRI, PET, SPECT) about the position and orientation relative to the patient of his surgical instrument to perform stimulation and treatment on brain structures or to a preplanned trajectory.

The software is capable of displaying the trajectory and functional areas of the brain based on BrainMAP online on the screen and recording the stimulations by storing positions of the electrodes.

The Functional Planning is intended to be used with patients where measurement, stimulation and placement of electrodes in the brain (pallidotomy) are part of the treatment. The stereotactic arc system is useful for placing these electrodes or using the instruments during the treatment and in the planning phases of the functional treatment.

In addition iPlan's indications for use is to prepare and present patient and image data based on CT, MR, X-ray(Fluoro) including

* image preparation

* image fusion

* image segmentation

where the result is preplanned data to be used by other BrainLAB medical devices such as VectorVision (for performing the planned treatment) where these medical devices are used for:

- Image Guided Surgery

BrainLAB's Image Guided Surgery system is intended to be an intraoperative image guided localization system to enable minimally invasive surgery where the image guided surgery system is indicated for any medical condition in which the use of stereotactic surgery may be considered to be appropriate and where a reference to a rigid anatomical structure, such as the skull, a long bone, or vertebra, can be identified relative to a CT, X-ray or MR based model of the anatomy.

Example procedures include but are not limited to:

* Cranial procedures

* Spine procedures

* ENT procedures

- FiberTracking

FiberTracking's indication for use is to prepare and present patient and image data based on MRI scanned with diffusion-weighted sequences. These diffusion images are used for the calculation and display of fiber bundles in a selected region of interest. The created treatment plans of iPlan! FiberTracking can be used with other iPlan! treatment plans and other BrainLAB medical devices such as VectorVision, where this medical device is used for image guided surgery.

- BOLD MRI

iPlan BOLD MRI indication for use is to prepare image data based on BOLD (blood oxygen level dependent) MRI scan studies and display the result as parametric images. When interpreted by a trained physician or surgeon this information may be used with other anatomical information for planning and image guided surgery.
