First measurements with a prototype liquid ionization chamber are described to be applied as an online-monitor for intensity modulated radiotherapy. The detector consists of 480 individual electronic channels which allow parallel read-out of radiation induced currents at frequencies exceeding 10 Hz. Dose gradients in the direction of leaf movement of a multileaf collimator have been measured and a reconstruction method for individual leaf positions has been developed. The achieved reconstruction accuracy will be described.
