Researchers take a 3D approach to breast density
Canadian and U.S. researchers have determined how measurements of volumetric breast density can be obtained from digital mammograms. The method builds upon previous work that allows the breast thickness to be determined precisely -- a key challenge when working in 3D.

Radiation therapy markers may have role in drug delivery
Given the proximity of inert implants such as fiducial markers and spacers to the target tumor, why not make more use of these devices? Researchers from Boston suggest they can be used to deliver radiosensitizing drugs or cytotoxic agents in situ, possibly improving efficacy without increasing radiation dose.

Optical sensor tracks radiotherapy treatment site breast motion
Postsurgical radiotherapy is an effective way of preventing breast tumors from reappearing, but the downside is the mismatch between ideal treatment plans and the doses actually delivered. Although conformal methods of delivery could address this issue, switching delivery techniques raises another potential problem: Will breast motion compromise the accuracy of a highly targeted radiotherapy regimen?

Can VMAT top IMRT for glioma treatment?
Intensity-modulated radiation therapy (IMRT) makes it easier to target brain tumors while reducing dose to critical structures nearby. But can volumetric-modulated arc therapy (VMAT) do even better? A retrospective planning study from Canada has revealed the pros and cons of making the switch.

VMAT bests IMRT for prostate cancer treatment time
In terms of dosimetric accuracy, volumetric-modulated arc therapy (VMAT) is comparable to step-and-shoot intensity-modulated radiation therapy (IMRT), but VMAT cuts treatment time considerably, according to research from Memorial Sloan-Kettering Cancer Center.

Breast IMRT without the overspill
An alternative intensity-modulated radiation therapy (IMRT) planning approach spares healthy structures from small, but significant, levels of radiation. IMRT has been recognized as a promising way to prevent breast cancer recurrence in patients who have opted for conservative surgery. Researchers in Alabama have devised a beam arrangement that delivers the benefits of IMRT, but without upping the low-dose overspill.

Good vibrations stave off blood-borne diseases
A therapy based on pulsed laser irradiation could selectively destroy viruses and bacteria without damaging healthy cells. Researchers from Arizona State University in Tempe asked what would happen if viruses and harmful bacteria were excited in the same manner by a pulsed laser. Could the unwanted micro-organisms be forced to shake themselves to pieces without harming useful cells?
