    Abstract: A radiation therapy device includes an electron beam source (EBS) for generating an electron beam and a steering device for directing the electron beam. A target is disposed a predetermined distance from the EBS and is positioned to intercept the electron beam. The target element generates x-ray photons upon the impact of electrons with the target. A focusing lens is coupled to and spaced from the target by no more than 10 mm, and is positioned to receive x-ray photons generated by the target. The focusing lens focuses the x-ray photons to a focal point. The radiation therapy device can also include targets configured to generate x-ray beams for tomosynthesis. A method for performing radiation therapy is also disclosed.

    Abstract: A balloon applicator for an intraoperative radiation therapy system includes an x-ray beam shaping component for emitting x-rays in a plurality of possible directions in three dimensions. The balloon applicator includes connecting structure for connecting to the intraoperative radiation therapy system and an inflatable balloon contactor having an outer surface. The balloon applicator has a beam hardening system including a beam hardening compound disposed between the x-ray beam shaping component and the outer surface of the balloon. The beam hardening system is capable of hardening the beam in beam directions in three dimensions. An intraoperative radiation therapy system and a method for conducting intraoperative radiation therapy are also disclosed.
