Texas Proton Therapy Center Treats First Patient with IBA Proteus Plus Gantry

System combines isocentric cone beam CT and pencil beam scanning for ultra-fine proton therapy

April 19, 2016 — Texas Center for Proton Therapy and IBA (Ion Beam Applications S.A.) announced the first patient treated in North America with the 360-degree Proteus Plus gantry. The system provides a high-precision tandem of iscocentric cone beam computed tomography (CBCT) guidance and pencil beam scanning.

Pencil beam scanning radiates tumors with an ultra-fine proton beam that requires precise positioning of the patient to ensure treatment accuracy. IBA’s Proteus Plus 360-degree gantry allows the acquisition of CBCT volumetric imaging at isocenter to assure precise patient positioning that effectively leverages the power of pencil beam scanning to provide the most accurate proton therapy treatment available. This unique combination of technologies allows Texas Center for Proton Therapy to provide treatment for indications demanding the utmost precision.

The multi-room Proteus Plus installation at the Texas Center for Proton Therapy has been in clinical operation since November 2015.
Andrew K. Lee, M.D., M.P.H., medical director at Texas Center for Proton Therapy, commented, “The combination of volumetric CBCT image guidance and pencil beam scanning begins a new era in proton therapy. This will allow proton therapy to help a wider range of cancer patients while improving the treatment for currently treated indications. This vital technology will help fulfill our joint mission to protect, enhance, and save lives.”
