![]() ![]() While working in the lab, we thought it would be good to try to bring augmented reality into the ablation process, allowing for an improved view in multiple dimensions of important structures to avoid and better visualization of the tumor and the ablation zone.” “It’s a difficult skill acquired over time that we hope to make more efficient and safer. “As interventional radiologists, we take it for granted that we look at 2D images, are able to convert them to 3D images in our heads, and perform the procedure on patients in three dimensions,” says Charles Martin III, MD, FSIR, an interventional radiologist at Cleveland Clinic and the senior author and lead investigator of the institutional review board–approved study. Those involved in the study believe holograms and 3D technology can improve visualization and guidance for everyone involved in the treatment of patients with liver or other abdominal soft tissue tumors. This is the first clinical use of this kind of AR guidance for this purpose. ![]() Researchers with the Cleveland Clinic recently presented data from a research abstract that showed the feasibility of using AR guidance with electromagnetically tracked tools to deliver targeted liver cancer treatments more effectively. “In tumor ablation, augmented reality can potentially improve the visualization and perception of the tumor and surrounding structures, helping to improve the treating physician’s confidence and, ultimately, make the procedure even faster, safer, and more effective,” says Gaurav Gadodia, MD, a radiology resident at the Cleveland Clinic. This is not to be confused with virtual reality, in which the user’s perception of reality is based on information that doesn’t physically exist. In the case of image-guided tumor ablation, 3D augmented reality (AR) can make the human anatomy, with its obstacle course of organs and vessels, more clearly visible.ĪR involves the enhancement of real-world environments by computer-generated perceptual information. Any enhancement of that reality, such as augmenting image guidance, could bring a clearer focus for interventional radiologists performing this method of cancer treatment. ![]() To make the situation more challenging, the mass may be round or oblong. Tumor ablation involves inserting a thin, needlelike probe through the skin to a targeted location-mapped out with CT, ultrasound, or MRI images-to treat a mass that could measure as little as 1 inch in size.
