A method for tracking an instrument during image-guided stereotactic surgery on a body, for instance during stereotactic brain surgery. The method includes attaching multiple bone anchors to the body, attaching scanning markers to each of the bone anchors, and scanning the body to form a three-dimensional image of the body. Images of the scanning markers are formed in the three-dimensional image and the locations of the images of the scanning markers in the three-dimensional image are determined, for example, by a human operator identifying the locations on a computer display of the image. The method then involves attaching a number of sensing devices, such as cameras, or microphones, to the bone anchors. For example, a mounting rod is attached to each of the bone anchors and each mounting rod supports one of the sensing devices. The mounted sensing devices are in a predetermined geometric relationship with the bone anchors. The instrument, which includes a tracking marker, is positioned in the field of
Neuronavigation, also termed frameless stereotactic surgery, is the ability to perform real-time intra-operative guidance during cranial and/or spinal surgery.
The present invention enables stereotactic surgery with a minimal structure present in order to facilitate surgery yet with enhanced accuracy in stereotactic imaging assistance to the surgeon. This device and method is known as frameless stereotaxis system, and uses coordinate referencing between the CT or MRI scans and a stereotactic referencing system which uses an electromagnetically driven system to determine the location of a stylus. Magnetic field distortion is reduced through the use of a low frequency magnetic field. The frame of reference through which this system operates is coordinate referenced to the coordinates of a composite image formed from a CT, MRI, or other system which are arranged and may be generated in two- or three-dimensional fashion in response to the position of a pointer (25) as they are referenced to the orientation of a patient (31) during an operation.

A stereotactic biopsy involves making a hole in the skull in order to take one or more small pieces of tumour for evaluation under the microscope (pathology). This procedure is done using advanced surgical navigation systems (stereotaxy), and sometimes involves the application of a stereotactic frame. Generally it takes a few days for a diagnosis to be confirmed, and there is a small risk of a "non-diagnostic biopsy" which may necessitate a further procedure.. Once the diagnosis is confirmed, a decision can be made about what further treatment is necessary, and in some cases this may involve a larger operation to remove the remainder of the tumour.. Compared with other neurosurgical procedures, a stereotactic biopsy carries relatively low risks. It is, however, a serious procedure and there is a small risk of bleeding, stroke, seizures, and even death. Your neurosurgeon should discuss these risks in detail with you before surgery is carried out. ...

A skin-based band is fixed to a patients skin in a repeatable position and includes reference markers which, attached to the skin band, can be visualized in tomographic image scanning. The reference markers appear as reference marker images in the image scan data from the image scan and correspond to coordinate positions in the image scan coordinate system. The reference markers also provide corresponding reference marker positions in the physical space of the patients anatomy, which may correspond to a stereotactic coordinate system associated with a digitized navigator or frameless stereotactic reference system near the patient. The band can also be placed on the patient again at the time of surgical intervention, and the reference markers can be touched or referenced by the surgical navigator in the stereotactic coordinate system. A computer system assimilates the image scan data and calibration data and enables a mapping from the image scan coordinate system to the stereotactic coordinate system

Brain biopsy side effects - I was wondering what are the after effects, if any, of a brain biopsy? Should be minimal. A stereotactic brain biopsy is done where a small needle is inserted into the brain under computer guidance. Care is taken to avoid hitting any important structures (blood vessels, nerves). There certainly are risks anytime one is operating in the brain. Depending on the location, there can be weakness/paralysis, and bleeding which can lead to stroke like symptoms, coma, death.
The reason to place a probe at a specific location in brain is to study localization of function in the brain. The brain is a very heterogeneous structure, and different sites and regions have different functional roles to play. Learning to understand that organization is one of the major goals of neuroscience, and requires regional studies of brain. Various stains and immune-markers can show regional chemical variation in brain. Stereotaxic insertion of probes - for stimulation, injection, recording, microdialysis, lesion or other functions - is an important technique to gain understanding of brain functional organization. Traditional stereotaxic instruments consist of a head holder that is aligned with a manipulator, with the manipulator movements measured by vernier scales with a resolution of 100 microns. A newer idea is to use digital scales in place of vernier, and obtain easier, less error prone reading and resolution to within 10 microns. Manipulators can be tilted and rotated, but doing ...

Background: The birth of stereotactic functional neurosurgery in 1947 was to a great extent dependent on the development of ventriculography. The last decades have witnessed a renaissance of functional stereotactic neurosurgery in the treatment of patients with movement disorders. Initially, these procedures were largely based on the same imaging technique that had been used since the birth of this technique, and that is still used in some centers. The introduction of new imaging modalities such as Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) provided new potentials, but also new challenges for accurate identification and visualisation of the targets in the basal ganglia and the thalamus with an urge to thoroughly evaluate and optimize the stereotactic targeting technique, as well as evaluate accurately in stereotactic space the location and extent of stereotactic Radiofrequency (RF) lesions and the position of deep brain stimulation (DBS) electrodes.. Aims: To study the ...

The concept of stereotactically standard areas (SSAs) within human brain nuclei belongs to the knowledge of the modern field of stereotactic brain microanatomy. These are areas resisting the individual variability of the nuclear location in stereotactic space. This paper summarizes the current knowledge regarding SSAs. A mathematical formula of SSAs was recently invented, allowing for their robust, reproducible, and accurate application to laboratory studies and clinical practice. Thus, SSAs open new doors for the application of stereotactic microanatomy to highly accurate brain targeting, which is mainly useful for minimally invasive neurosurgical procedures, such as deep brain stimulation.
