This effect is referred to as skin sparing and is desirable for most photon treatments.. Depth of Maximum Dose (d max). The depth of maximum dose is closely connected to photon energy but also source-to-surface distance, field size and beam …

Web15 apr. 2014 · Semi-out-of-universe we see how fast a phaser beam is: I'd estimate something around 80 kph. You can see it moving with the naked eye. But that might be just a way to tell a story; to establish causality to the audience: "Look! First the beam is here, now it's here, now something's exploding."
