This is kind of an ancient thread, but I wanted to bump it to bring your attention to an important report in the latest Red Journal.
American Society for Therapeutic Radiology and Oncology (ASTRO) Emerging Technology Committee report on electronic brachytherapy.
Park CC, Yom SS, Podgorsak MB, Harris E, Price RA Jr, Bevan A, Pouliot J, Konski AA, Wallner PE; Electronic Brachytherapy Working Group.

I tried to upload the whole article but unfortunately it exceeds the attachment size limit.
Anyway, I wanted to draw your attention to a key point,
In some juristictions, no user regulations are in place, so there is no requirement for a radiation oncologist to be involved in the procedure, although a physicist is typically required to perform pretreatment calibrations and intraoperative monitoring. Therefore intraoperative EBT [electronic brachytherapy] could potentially be performed by a surgeon or other personnel who have no expertise in radiation treatment of caner, brachytherapy principles, radiation safety and biology, or normal tissue tolerances.
A few more interesting points brought up by the report:
1. These are medical devices not drugs so their FDA approval does not require proof of their efficacy.
2. Since these devices electronically generate brachytherapy rather than with isotopes, they are not regulated by the NRC. Therefore they are not explicitly subject to regulations regarding calibration and quality assurance.
3. These devices are not without side effects and these may not be appropriately managed by non-radiaiton oncologists.
As future radiation oncologists we should be aware of these issues and (as much as possible) try to participate in randomized clinical trials (such as TARGIT for breast).
