CASS SurgiPlan Module

The CASS SurgiPlan System is the fundamental imaging system for the CASS Family of Computer Imaging Systems for stereotaxy. CASS SurgiPlan provides accurate pre-op, operative and post-op simulation and planning. CASS SurgiPlan is a complex integration of various hardware components in a user-friendly software environment.

CASS SurgiPlan is a multi-modality imaging system which allows acquisition of images from any scanner, including CT, MR, DSA, PET, SPECT, etc. Images are converted into a standard format for surgical planning.

CASS SurgiPlan runs on the high performance Silicon Graphics workstations.


Features

Multimodality Imaging with CT, MR, and Angiographic image data sets showing a large frontal foam cell astrocytoma. Stereotactic probe data is cross correlated between the different image data sets. Volume data is also translated between the image data sets. Note probe coordinate position and trajectory determination below.

Multi-Modality Image Acquisition

Images can be acquired by Ethernet, tape, or camera interface. MIDCO can also provide our specially designed programmable digital interface for direct image transfer from various scanners.
These acquisition modules allow flexibility and include the following capabilities:

  • Image capture from various scanner devices.
  • Acquisition of DICOM 3 images.
  • Storage in a standard format - up to 400 captured images in the system per patient.
  • Archiving of all stored images.

Multi-Modal Image Manipulation
This feature provides for the manipulation of stored images, and consists of routines that enhance, contrast, and color the images. Included in this feature are routines for:

  • Pixel Analysis of the entire image, including Edge Detection, Ramping, Windowing, and Colorization.
  • Various methods of Reduction and Enlargement of specific areas of interest in an image.
  • Contrasting, Smoothing, and Sharpening of images
  • Image Comparison and Image Editing

Multi-Modal Image Building
This feature provides the surgeon with several methods of enhancing the conceptualization of a procedure. Included in Image Building are routines for transforming and aligning images using size and positional algorithms, transparent viewing of images for comparison of different scan techniques, and routines for various 3-D simulations. Features included in the Image Building routines are:

Multi-Modal Fusion In this image, a PET image with a hypermetabolic temporal lobe is overlaid on a MR image for composite display. Various combinations of MR, CT, PET, SPECT, etc. can be combined in various combinations for cross correlation and data transfer.

By using the CASS image fusion feature, images from various sources can be overlaid for comparison and data transfer. In this image, a PET image with a hypermetabolic temporal lobe is overlaid on a MR image for composite display. Various combinations of MR, CT, PET, SPECT, etc. can be combined in various combinations for cross correlation and data transfer.

  • Perspective View - for viewing the probe through stacked images
  • MultiView - to simultaneously see the probe in sagittal, frontal and horizontal windows
  • 3-D Imaging and Simulation

Universal Probe/Electrode Positioning

Universal Probe/Electrode Positioning

This feature provides a method for determining the placement of a surgical probe/electrode within the brain, and is designed to work in conjunction with any stereotactic frame. Features within the Probe routines are:

  • Graphical simulation of the probe in the brain, along with a display of the probe's intersection with various scanner image planes
  • Rapid determination of the stereotactic frame coordinates for positioning of the probe






Multiple Measurement Capabilities
Rapid routines for coordinate, point-to-point, area and volume determinations.
