Tami Freeman[email protected]Radiation Oncology/TherapyProton therapy experts look back and to the futureProton therapy as a cancer treatment has been making gains, but it's years away from becoming mainstream. What's happened over the past five years? Medicalphysicsweb takes a look at the evolution of this intriguing form of cancer treatment.September 11, 2011Radiation Oncology/TherapyAdvances in IMRT discussed in honor of technology pioneerWith the clinical success of intensity-modulated radiotherapy (IMRT), research is now focused on optimizing and evolving IMRT techniques. Three distinguished medical physicists recently examined the current state of the art and future directions in advanced IMRT planning, quality assurance, and image guidance.August 22, 2011Nuclear MedicineSPECT tracer could cut staging costs for NSCLCThere may be an alternative to non-small cell lung cancer (NSCLC) diagnosis and staging using FDG-PET: low-cost SPECT imaging with a new molecular imaging agent, according to research from MD Anderson Cancer Center and biopharmaceutical company Cell>Point.August 5, 2011CTNew phantoms ramp dose estimate accuracy for imaging examsComputational human phantoms are invaluable for calculating radiation dose, but the determined values are only strictly accurate for patients with exactly the same anatomy as the phantom. Researchers in Brazil have created a new diverse series of phantoms to improve the situation.July 3, 2011Radiation Oncology/TherapyDevelopments in managing motion described at ESTROImage guidance plays a vital role in modern radiotherapy, helping to reduce the impact of both interfraction and intrafraction motion. A session at the European Society for Therapeutic Radiology and Oncology (ESTRO) meeting, held last month in London, examined some recent developments in this field.June 21, 2011Radiation Oncology/TherapyProton therapy: Is randomization needed?Are randomized clinical trials appropriate for demonstrating proton therapy's superiority to x-ray therapy? The European Society for Therapeutic Radiology and Oncology meeting, held last month in London, was the venue of a contentious debate on this subject.June 8, 2011BreastPhotoacoustic and US tomography vie for breast imaging rolesMammography is the established method for breast cancer screening, with MRI often employed to follow up suspect lesions. But both have their limitations, spurring the development of alternative modalities such as photoacoustic and ultrasound tomography for breast imaging.March 24, 2011BreastDBT offers potential for super-resolution imagingDigital breast tomosynthesis (DBT) is an emerging imaging modality in which tomographic images of the breast are generated from multiple 2D x-ray projection images. But DBT can deliver much more -- it also offers the potential for super-resolution (subpixel) imaging.March 9, 2011Artificial IntelligenceQuality assurance is essential for CAD to thriveComputer-aided detection (CAD) technology has experienced rapid growth over the past two decades, but the output in terms of commercial clinical products has been small. The 2011 SPIE Medical Imaging conference held last month dedicated its keynote speech to explaining why.March 8, 2011UltrasoundAlgorithm aids breast lesion classificationWith angiogenic vasculature in breast lesions indicating malignancy, contrast-enhanced ultrasound could provide a means for determining malignancy based on blood flow. Researchers from Thomas Jefferson University are investigating the use of subharmonic contrast-enhanced ultrasound for this purpose.February 17, 2011Previous PagePage 2 of 4Next PageTop StoriesInterventionalARRS: MWA safe, effective method to treat bone metastasesUltrasound-guided microwave ablation (MWA) is a safe, effective method for treating bone metastases.Artificial IntelligenceACR responds to Congressional query on AI reimbursementISMRM 2024ISMRM: MRI useful in predicting tumor response in breast cancer patientsISMRM 2024ISMRM: PET/MRI shows promise identifying musculoskeletal ‘pain generators’Sponsor ContentWe care about what you think.
