Using Volume Navigation on the LOGIQ E9, image fusion of 2D ultrasound and CT made it possible to visualize a difficult target. Using eTRAX Needle Tip Tracking was beneficial to obtain proper access to the obscurred target and continuously visualize the needle tip as it was advanced.
Patient presented with a difficult-to-see pancreatic abscess. Accurate access was aided by eTRAX Needle Tip Tracking’s projection and pathway for advancement the needle. Use of an ultrasound overlay with CT revealed the required entry point.
Patient presented with pancreas carcinoma with liver metastases. eTRAX is useful for visualization in non-neoplastic liver tissue.
In this clinical case, the lesion is approached using a microconvex probe, with a trajectory that is almost parallel to the ultrasound beam. In such a case, the needle is hardly visible with ultrasound alone.
The authors presented a correlation study using Computed Tomography (CT) that compared the differences between using a freehand and needle-guided ultrasound biopsy technique. The purpose was to assess the accuracy of the needle position in relation to the target and to quantitatively characterize the time required to insert a needle to the target and the number of needle passes required to reach the target using each technique.
In this clinical investigation, the authors conduct a study to evaluate the accuracy and safety of electromagnetic needle tracking for use during ultrasound-guided percutaneous liver biopsy. Using a 16-gauge eTRAX™ Needle Tip Tracking system as a cannula, two 18-gauge tissue cores were retrieved using an automated biopsy needle and an ultrasound system with positioning sensor technology. In total, 23 liver biopsy procedures were performed. The majority of the procedures were completed using an in-plane approach, however, the out-of-plane approach was utilized during cases deemed inconvenient or unsafe for the traditional method.
Since the spring of 2016, the growth of ultrasound in the United States has erupted with the FDA approval of contrast for liver examinations. The contrast agents used for ultrasound… read more →
When ultrasound is used for point-of-care needle guided procedures, including vascular access or regional anesthesia, it is recommended by the FDA and the CDC that a single-use, disposable probe cover… read more →
This case demonstrated that monitoring of electrode tip using VirtuTRAX is feasible and helpful for thyroid RFA. The VirtuTRAX device could increase the accuracy and the outcome of thyroid RFA while reducing the complication rate, shortening the procedure time and learning curve.
An in vivo swine study was performed to assess the overall targeting accuracy of an ultrasound system with navigation technology, electromagnetic tracking and needle sensor technology embedded within the needle tip and placed a the hub of the needle. The target accuracy of the two techniques was then compared to a free-hand technique. Metallic targets were embedded into the paraspinal muscle, kidneys and liver of the swine model. CT data sets were used in combination with real-time ultrasound imaging to evalaute the Virtual Navigator’s response to respiratory motion and targeting accuracy in a live model.
