Experts discuss proton therapy's potential for breast cancer
Proton therapy is currently used to treat brain, spine, and prostate cancers, as well as many pediatric tumors. Earlier this month, experts from some of the leading U.S. cancer centers gathered to discuss the emerging role of proton therapy in breast cancer.

Hybrid linac-MRI tracks motion during radiotherapy
Real-time tumor tracking could prove invaluable for radiotherapy of moving targets such as lung tumors. Using MRI for such tracking provides position verification without ionizing radiation. Researchers recently discussed the latest results of a prototype hybrid linac-MRI system being developed at the Cross Cancer Institute in Canada.

Exploiting log files for optimal radiotherapy QA
Quality assurance (QA) of intensity-modulated radiation therapy (IMRT) is a vital component in the radiotherapy process, but current QA procedures are far from optimal. Log files produced by radiotherapy systems can be exploited to vastly improve IMRT quality assurance.

Imaging advances therapy assessment
Monitoring and understanding a patient's response to therapy plays a central role in optimizing cancer treatment. Advanced imaging technologies could enable monitoring of tumor response at an earlier stage in the treatment course, providing a means for personalized therapy adaptation.

New takes on image guidance for radiation therapy
Kilovoltage and megavoltage conebeam CT are predominantly used for real-time imaging during radiation therapy, with systems based on ultrasound or MRI now also being developed. But there are other imaging modalities that could be used, including those that offer functional and molecular information regarding the tumor being treated.

MRI visualizes proton dose distribution
MRI visualizes the dose distribution with proton therapy procedures by imaging radiation-induced tissue changes, reducing the uncertainty of the range of the proton beam, according to a presentation at the recent European Society for Radiotherapy and Oncology annual meeting.

Brain PET enhances radiation therapy planning
A brain PET scanner based on semiconductor detectors can provide more accurate tumor delineation than a conventional whole-body PET system, according to researchers from Japan, who found that the newly developed system had twice the spatial resolution of conventional PET systems.

Couch attenuation undermines radiotherapy plan quality
Treatment couches used to support a patient during intensity-modulated radiotherapy and arc therapy can unknowingly lead to an unacceptable reduction in dose to target structures. Rail placement can also affect the dose delivered.

Ultrasound tackles radiation therapy guidance
Ultrasound imaging offers the potential of marker-free, soft-tissue visualization during radiation therapy delivery, providing real-time tracking of target organ location without delivering any extra radiation dose to healthy tissue.
