Stereotactic body radiotherapy (SBRT) involves image-guided, ablative radiation delivered to cancer targets refractory to chemotherapy or to conventional radiation treatment. The robotic-armed Cyberknife SBRT system, using sophisticated target localization, delivers hypofractionated radiation doses capable of sterilizing cancer targets. This article will consider new therapeutic roles of SBRT for gynecological cancers.

Stereotactic ablative body radiation therapy (SBRT) involves the precise delivery of high-dose radiation to cancer tumor targets. A novel SBRT platform offers a first-of-its-kind gimbaled radiation accelerator mounted within a pivoting O-ring gantry capable of dynamic image-guided tumor tracking. Here, we describe dynamic tumor tracking for lung targets.

This video demonstrates a stereotactically-guided surgical procedure for ablating the auditory cortex in a rat. The steps include identifying anatomical landmarks in an anesthetized rat secured in a stereotactic frame, creating a window on the skull above the auditory cortex, aspirating the cortical layers, and providing post-operative care to assess the impact of the ablation on sound processing.

Stereotactic injection of lentiviruses expressing cDNAs or shRNAs can modulate gene expression in specific brain areas of mice. Here, we present a protocol to combine stereotactic injections with behavioral tasks, such as the Open Field Test (OFT) and the Forced Swim Test (FST).
FAQs
Three-dimensional coordinates convert information from medical images into a spatial framework for identifying a surgical target. This framework allows the team to relate the planned target to surrounding anatomy and select a precise location for intervention. In practice, coordinate-based planning helps organize image-guided procedures that require consistent access to a specific structure.
A stereotactic frame or frameless navigation system connects the planned coordinates with the patient’s anatomy during preparation for surgery. These systems provide the structural basis for locating the target identified on MRI or CT data. Using either approach, the surgical plan can be aligned with the intended site before an intervention begins.
Trajectory planning helps define the route toward a target while accounting for nearby critical anatomy. This step matters because stereotactic procedures are intended to improve spatial accuracy and minimize disruption to healthy tissue. Reviewing the target and surrounding structures together supports a more controlled approach to biopsies, ablation, stimulation, or targeted delivery.
MRI or CT data supply the images used to map the target within the body, particularly in the brain. The selected images are incorporated into the three-dimensional planning framework so the target, surrounding anatomy, and proposed trajectory can be considered together. This image-based preparation supports more precise, consistent image-guided interventions.
Planning begins by using MRI or CT data to locate the intended structure in three dimensions. The team then defines a target and establishes a safe trajectory while considering nearby critical anatomy. Finally, the plan is coordinated with a stereotactic frame or frameless navigation system, creating an image-guided basis for the planned procedure.
The approach supports several targeted procedures, including biopsy, lesion ablation, deep brain stimulation, and targeted drug delivery. Although these interventions have different purposes, each benefits from locating a specific structure and planning access with spatial precision. The same planning principles therefore apply across diagnostic, therapeutic, stimulation-based, and delivery-focused procedures.
Stereotactic planning advances image-guided medicine by linking medical imaging with coordinate-based targeting and trajectory design. Its emphasis on spatial accuracy can help surgeons limit disruption to healthy tissue and promote safer, more consistent interventions. These capabilities also support continued development of procedures that act on precisely selected structures rather than broader regions.
