Proton Therapy QA

Qplus

Replace the use of Gafchromic films for 2D spot characterization

WHAT?

QPlus is the ideal all in one QA devices to get profile measurements of beam spots in ocular proton treatment.

WHERE?

QPlus is designed to be placed at the isocenter of passive scattering lines for 2D spot characterization.

WHEN?

QPlus is conceived to speed up routine quality assurance measurements and replace the use of Gafchromic films.

WHO?

QPlus is aimed at medical physicists looking for reliable, fast and innovative device for profile characterization of ocular proton beams.

HOW?

Qplus has a special dotted pad along X and Y direction with 63 measurement points of 0.5 mm diameter at a pitch of 0.6 mm along vertical and horizontal direction.

WHY?

QPlus includes dedicated software, power supply and electronic interfaces for an easier setup and a enhanced signal-to-noise ratio
