Advances showcased include offerings in Computed Tomography (CT), Magnetic Resonance (MR), and Positron Emission Tomography-CT (PET/CT) that address vital clinical and technology needs in radiation oncology like never before.
One focus of the
CT - Metal Artifact Reduction (MAR); Deviceless 4D; Advanced virtual simulation
When utilizing CT scans, clinicians are often challenged by image distortions caused by high-z metals in the body such as prosthesis, screws or dental fillings. Metals often generate streak-like artifacts in CT scans, making it difficult to clearly delineate between tumors and healthy tissue. Smart MAR addresses this challenge with an innovative multi-step projection-based method. This automated approach is designed to reveal anatomic details obscured by metal artifacts.
Until now, motion-compensated 4D CT solutions have required the use of an external respiratory monitoring device, which may complicate and slow the exam process through device set up, introduce device-related errors and create workflow challenges.
AdvantageSim MD version 9 helps improve productivity with new tools for planning of routine and advanced delivery techniques such as adaptive radiation therapy with CT atlas-based contouring and re-planning. AdvantageSim MD 9 also supports various planning workflows and access from virtually any networked PC or the CT simulator console.

MR - GEM RT Open Head & Neck Suite
Now 510(k) cleared and CE marked, the 1.5T GEM RT Open Head & Neck Suite combined with GE's Optima* 450w GEM MR scanner, enables high-resolution, large field of view scanning of the head and neck. The array was designed specifically for imaging for radiation therapy planning with an open design and flexible GEM coils that conform to the patient's anatomy and impact patient comfort while delivering excellent image quality in the treatment position.
PET/CT - Volume Computer Assisted Reading (VCAR); Q. Freeze
PET VCAR streamlines the assessment of metabolic data, and when integrated into the OncoQuant* oncology platform, can provide the ability to compute Standard Uptake Values (SUV), to measure metabolic activity and volume for PET defined areas of activity, and compare CT, PET/CT, and MR studies for baseline and follow-up studies using the PERCIST method.
Designed to combine the quantitative benefits of 4D phase-matched PET/CT imaging into a single static image, Q.Freeze addresses each of these challenges by creating a single static image corrected for respiratory motion using a low dose CT technique. It uses 100 percent of the PET counts collected, in combination with a low dose CT acquisition to remove PET/CT attenuation correction mismatch, to provide the best possible image quality. A robust and reliable non-rigid registration technique based on a multi-resolution optical flow methodology corrects PET data for respiratory motion. The resulting image has multiple benefits: frozen patient motion, reduced image noise and consistent quantitative accuracy.
