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.

Begin with an anesthetized human patient with an exposed skull. The patient is diagnosed with an intracranial tumor.Drill into the exposed skull to create a hole, generating an access point.Using stereotactic guidance, insert a laser diffusing fiber or LDF along the predetermined path and secure it in place.Transfer the patient to an MRI scanner and connect the LDF to a laser source.Capture MRI images from multiple angles to visualize the fiber path and the tumor.This confirms the LDF’s...

Pulmonary vein isolation (PVI) with an ablation catheter is a curative treatment for atrial fibrillation (AF). Robotic catheter systems aim to improve catheter steerability. Here, a procedure with a new robotic catheter system is presented. The goal of the procedure is electrical block between pulmonary vein and left atrium.
FAQs
The treatment concentrates heat, cold, electrical energy, laser energy, or a chemical agent at a selected abnormal area, producing a localized lesion. Imaging, catheter guidance, or physiologic monitoring helps clinicians direct the treatment and assess its effect while limiting exposure of surrounding structures. The intended result is symptom relief, disease control, or restoration of normal function.
A successful result depends on placing the treatment at the correct abnormal tissue and producing an appropriate local response. If targeting is inaccurate or tissue reacts unpredictably, the intended lesion may not control the disease or restore function as expected. These variables make procedural planning and careful monitoring important parts of clinical decision-making.
Ablation therapy may use heat, cold, electrical energy, laser energy, or chemical agents to create the treatment lesion. The available source can vary with the condition and the tissue requiring treatment, while the shared objective remains precise destruction or removal of abnormal tissue. This range of modalities allows the approach to be adapted to different localized disorders.
Clinicians may use imaging, catheter guidance, or physiologic monitoring to locate the target, guide treatment delivery, and help limit injury to nearby structures. The appropriate combination depends on the clinical problem and treatment setting. These tools support precision by linking the intended treatment site with observable anatomic or functional information during the procedure.
In cardiac care, the treatment can interrupt faulty electrical pathways that contribute to an arrhythmia. By creating a targeted lesion in the relevant pathway, clinicians aim to stop abnormal electrical conduction and help restore normal cardiac function. Catheter guidance and physiologic monitoring can support accurate localization and assessment of the tissue responsible for the rhythm disturbance.
The approach may be considered when abnormal tissue is localized and its destruction or removal could relieve symptoms or control disease. Clinical uses described include selected tumors, certain pain-generating tissues, and other localized disorders. Whether it is appropriate depends on accurate targeting, the tissue response expected, and patient selection for the particular condition.
