A new accessory device enhances the BRW stereotactic system for precise angiographic data localization. This improves the calculation of target points and stereotactic coordinates for neurosurgical planning.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Biomedical Engineering

Background:

  • The Brain Research and Development (BRW) stereotactic system is a critical tool in neurosurgery.
  • Accurate localization of neurovascular structures and lesions is essential for effective surgical planning.
  • Integrating angiographic data with stereotactic coordinates presents a technical challenge.

Purpose of the Study:

  • To introduce an accessory device for the BRW stereotactic system.
  • To enable precise localization of angiographic data within the BRW stereotactic space.
  • To facilitate the calculation of stereotactic coordinates for neurovascular targets and lesions.

Main Methods:

  • Development of an accessory locating device compatible with the BRW stereotactic system.

  • Utilizing the device as a reference for aligning angiographic data (e.g., from CT scans) with the stereotactic system.
  • Calculating the projection of target points onto angiograms and determining stereotactic coordinates from multiple angiograms.

    • Main Results:

    • The accessory device allows for accurate referencing of angiographic data to the BRW stereotactic system.
    • Stereotactic coordinates of points, such as those in arteriovenous malformations (AVMs), can be calculated from at least two angiograms.
    • Projection of target points onto angiograms visible on CT scans is easily calculated.

    Conclusions:

    • The developed accessory device significantly enhances the capabilities of the BRW stereotactic system.
    • It enables precise integration of angiographic information for improved neurosurgical planning.
    • Future applications include generating integrated images of cerebral blood vessels and tumor outlines.
