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.

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
Clinicians combine three-dimensional imaging with anatomical landmarks to identify a precise internal target. These reference points allow the team to calculate coordinates and select a trajectory for the implant. The coordinate-based plan is especially important when the target is small or difficult to reach, because consistent positioning can support accurate placement while limiting disruption to nearby tissue.
Frame-based procedures use a stereotactic frame to establish a stable spatial reference for calculating and guiding the implant path. Frameless systems use navigation technology instead of a fixed frame to support the same coordinate-based approach. Both methods are intended to guide an electrode, catheter, marker, or other device toward a planned anatomical location with high precision.
Trajectory planning determines how the device travels from its entry point to the intended target. A carefully selected path helps clinicians reach structures that may be deep or otherwise difficult to access while limiting injury to surrounding tissue. This planning principle supports treatment consistency and is central to interventions that depend on accurate access to small anatomical regions.
The process begins by defining the target with three-dimensional imaging and anatomical landmarks. Clinicians then calculate the target coordinates, establish a planned trajectory, and use either a stereotactic frame or frameless navigation system to guide the device. Depending on the clinical goal, the implanted object may be an electrode, catheter, marker, or another specialized device.
Its applications include deep brain stimulation, targeted drug delivery, and lesion localization. The technique is selected when a clinician needs to access a precise internal site, particularly a small or difficult-to-reach structure. Because the approach can improve placement consistency, it supports both therapeutic interventions and procedures that require reliable anatomical targeting.
In neurological research, precise placement of electrodes, catheters, markers, or related devices can support investigations of disease and brain function. The approach provides a way to connect a planned anatomical location with an intervention or localized observation. Its accuracy can improve consistency across procedures, helping researchers study neurological disease and brain activity more systematically.
