Researchers studying cancer and other invasive diseases rely on high-resolution imaging to see tumors and other activity deep within the body’s tissues. Using a new high-speed, high-resolution imaging method, Lihong Wang, Ph.D., and his team at Washington University in St. Louis were able to see blood flow, blood oxygenation, oxygen metabolism and other functions inside a living mouse brain at faster rates than ever before.

Varian Medical Systems last week unveiled a radiotherapy platform designed to offer clinics an affordable option for implementing advanced image-guided radiotherapy. Varian's VitalBeam system is a cost-effective technology package for offering high-quality, high-throughput radiation therapy, and for expanding clinical capabilities over time.

Brainlab expanded on its “Elements” strategy for treatment of brain and spine tumors with the introduction of automated stereotactic radiosurgery (SRS) planning tools. Announced at the third European Society for Therapeutic Radiology and Oncology (ESTRO) Forum in Barcelona, Spain, the SRS tools enable on-the-fly generation of consistent treatment plans for volumetric arc therapy (VMAT) delivery.

Volpara Solutions announced the release of VolparaDensity version 3.1 at the Society of Breast Imaging’s SBI/ACR Breast Imaging Symposium in Orlando, Florida, April 25-28.

Ion Beam Applications S.A. (IBA) and Pravida Bau GmBH announced an agreement to supply integrated single-room proton therapy solutions to customers in Europe.

Results from a randomized controlled trial comparing permanent radioactive implants (brachytherapy) with dose-escalated external beam radiotherapy in patients with prostate cancer showed brachytherapy patients were twice as likely to be cancer-free five years later.

The American Society of Radiologic Technologists (ASRT) has introduced Low-Dose Computed Tomography (LDCT), an online education product designed to teach radiologic technologists LDCT screening techniques for patients with lung cancer. The module also provides guidance for radiology managers looking to provide reimbursable LDCT services to patients in the Medicare program.

Radiotherapy using protons can deliver more accurate treatment to a tumor while reducing the dose to surrounding tissue. However, in mobile organs such as the lung, precise targeting of the dose is difficult. Now researchers have succeeded in making a model of breathing movement that allows for the precise measurement of narrow beams to a dummy tumor by simulating the motion and physical properties of the chest anatomy in a model, which was presented at the 3rd European Society for Radiotherapy and Oncology (ESTRO) Forum in Barcelona, Spain.
