Expansion of stereotactic work envelope using transformation matrices and geometric algebra for neurosurgery.
Biomed Eng Lett
January 2025
NaviNetics, Inc, Rochester, MN USA.
Stereotactic systems have traditionally used Cartesian coordinate combined with linear algebraic mathematical models to navigate the brain. Previously, the development of a novel stereotactic system allowed for improved patient comfort, reduced size, and carried through a simplified interface for surgeons. The system was designed with a work envelope and trajectory range optimized for deep brain stimulation applications only.

: To report on the first results of safety, efficacy, and outcome of CT-navigated stereotactic percutaneous electrochemotherapy (SpECT) in patients with primary and secondary liver malignancies. : This retrospective study included 23 consecutive lesions in 22 patients who underwent SpECT for primary and secondary malignant liver lesions with locally curative intention. The endpoints were primary technique efficacy (PTE), local tumor progression (LTP), time to progression (TTP), and occurrence of adverse events.

: To evaluate the efficacy and safety of the Surgnova Dophi™ M150E microwave ablation system in a prospective single-center observational study. : A cohort of 50 patients with 77 primary or secondary liver tumors underwent CT-navigated stereotactic percutaneous microwave ablation with curative intention using the Surgnova Dophi™ M150E system. The endpoints were primary technique efficacy (PTE), number of complications, ablation defect dimensions, and sphericity index compared to previously reported findings.

Background: Parafalcine subdural hematomas (pSDHs) are a subtype of subdural hematoma (SDH) that occur most frequently in older patients after blunt trauma. The literature primarily describes two clinical courses for patients with pSDH: those who are neurologically intact with stable examinations and imaging and those with focal deficits, with or without hematoma progression. Surgical management is undoubtedly required for the latter group; however, there are no evidence-based guidelines specifically for pSDH.

Unlabelled: Brain morphology understanding is essential for radiologists, neurologists, and neurosurgeons. Historically, anatomical learning of brain relied on ex vivo specimens. Modern in vivo brain CT and MRI provide spatial, three-dimensional imaging capabilities crucial to help diagnose diseases, plan surgeries, and monitor treatment progress.
