GE Healthcare introduced its new Discovery RT radiation therapy planning CT system this week at the American Society for Radiation Oncology (ASTRO) 57th annual meeting. Many of the system’s new features assist radiation oncologists with more complex treatment plans and setups.
The Discovery RT is essentially a CT simulator that generates a 3-D image data set that physicians can use to localize the tumor and plan treatment without needing the patient to be present physically. The system is equipped with many features that make patient positioning more flexible, address motion and metal artifact issues, and allow for precise treatment planning and a more efficient workflow.
The system has an 80 centimeter bore and an 80 centimeter field-of-view, which is enabled by the Max Field of View (MaxFOV) feature that delivers CT images with specific spatial and density position to the edge of the bore. Both the wide bore and MaxFOV feature allow physicians to place patients in different treatment positions and image their full volume.

Its Smart Deviceless 4D technology evaluates patient motion without the use of an external respiratory gating device and displays images of all the phases of a breathing cycle. The system combines that technology with the Smart Metal Artifact Reduction (MAR) technology to tackle both the challenges of motion and metal.
Metal implants such as hip prostheses, screws, and dental fillings often cause artifacts on CT images, which makes it hard to distinguish between tumors and healthy tissue. Smart MAR reveals the anatomic details that were hidden by the metal artifacts by reducing photon starvation and beam hardening.
GE also showcased its MR Radiation Oncology Suite at the meeting, which includes a full range of coils, positioning devices and pulse sequences. Its Discovery PET/CT was also on display with the Q.Clear reconstruction engine that improves the quantitation accuracy and image quality by up to two times.
The Discovery RT, MR Radiation Oncology Suite, Discovery PET/CT, as well as the SIGNA PET/MR and ExAblate MR-guided focused ultrasound system make up GE’s radiation oncology portfolio. The Discovery RT and MaxFOV does not yet have CE mark.
