During interventional therapy a good three-dimensional pathology visualization is often critical for precise treatment planning, image guidance and monitoring.
XperCT has clinically proven over the past years its equivalence to conventional CT in many interventional procedures 1-2.
Cone-Beam CT can be challenging when used for large and bariatric patients.
Its image quality remains vulnerable to patient movements and artifacts caused by metal implants, clips or contrast filled catheters. |
Philips' next generation XperCT features hi-res, conebeam CT imaging that is designed to enhance speed and precision for challenging interventions. It helps clinicians visualize bone, soft tissue, and contrast enhanced vessels with superb resolution. The clinically fine-tuned XperCT protocols and innovative imaging filters have been developed to improve visualization for different anatomical areas and devices.
Advantages of the enhanced XperCT
- Very fast imaging protocols for greater patient comfort, excellent image quality and fewer breathing and motion artifacts
- Reduced metal artifacts from clips, coils & contrast-filled catheters
- Excellent Image Quality for large and bariatric patients without requiring additional radiation dose

Very fast imaging protocols for greater patient comfort and better image quality
In the interventional suite Cone beam CT image quality is essential for planning, guiding, monitoring and controlling the outcome of interventional procedures.
However, when treating critical patients, its image quality is often compromised through motion and breathing artifacts. This is particularly true when performing abdominal examinations on fragile patients who often have difficulties to hold their breath.
We improved our industry leading XperCT to perform Thorax and abdominal scans in just 4 and 5 seconds. Thanks to the new acquisition protocols, which deliver very fast cone beam CT scans we can now target excellent image quality while ensuring higher patient comfort with less motion artifacts.
Reduced metal artifacts from clips, coils & contrast-filled catheters
Visualization around metal objects often poses challenges, making difficult to assess the anatomy in the vicinity of metal implants, coils, or stainless steel stents.
For these cases XperCT provides a unique Metal Artifact Reduction filter, which significantly reduces the scattering artifacts in Cone-Beam CT.
Excellent Image Quality for large and bariatric patients without requiring additional radiation dose
XperCT has been designed to enhance the treatment of challenging cases, such as obese patients. Our unique BMI Noise Reduction filter has the potential to improve the Image Quality for large and bariatric patients without requiring additional radiation dose.
BMI Noise Reduction filter reduces streaking artifacts in the reconstructions of these patients when an abdominal XperCT scans is performed. The filter can be applied to the initial scan to improve the image quality without any risk of exposing the patient to additional X-ray radiations.
Applications
- Interventional Oncology: The combination of 3D soft tissue imaging with vasculature can help clinicians better identify the location of a tumor and its feeders. The fast 5 second scan reduces the impact of breathing or motion artifacts in abdominal procedures and provides excellent image quality while requiring a very short breath hold for critical patients.
- Neuroradiology: XperCT supports the visualization of opaque intracranial devices, such as the struts or kink in a stent, while at the same time visualizing brain hemorrhages. It also provides superb image quality when imaging areas where a coil or stent is present.
- Endovascular radiology interventions: The enhanced image quality of XperCT improves the visualization of pathologies, such as endoleaks, and assist in the treatment of large patients by providing improved Image quality.
