    When using the hd120 mlc for beam shaping and under specific treatment conditions dose may be delivered outside of the intended treatment field that exceeds the expected transmission dose. this dosimetric property which has been discovered under very specific use conditions with dynamic fields and the hd120 mlc can lead to dose values significantly higher than expected in areas several centimeters away from the edge of the field. the effect is detectable for static mlc cases but only dynamic mlc (imrt) cases were considered to have any potential for significant unexpected dose.
