Tami Freeman, PhD[email protected]Clinical NewsSolar power brings imaging to Himalayan villagesWith no central power grid or infrastructure in the region, clinical staff members relied exclusively on solar power to deliver imaging to remote mountain communities in the Himalayas. They used a low-cost, lightweight solar panel; a handheld ultrasound unit; and a tablet to display the images.April 3, 2019Radiation Oncology/TherapyFocused ultrasound releases cancer drugs on targetResearchers from the U.K. are using computational planning models to determine the focused ultrasound parameters required to release drugs from liposomes, without the need for real-time thermometry. This approach could make ultrasound-mediated targeted drug delivery more widely accessible and simpler to administer than techniques that use MRI guidance.March 28, 2019Clinical News3D printing enables gel dosimetry in complex phantomsPolymer gel dosimeters can measure complex 3D dose distributions for use in patient-specific radiotherapy quality assurance. German researchers have investigated the use of 3D printing to create polymer gel phantoms with arbitrary geometries.March 6, 2019Clinical NewsMRI optimizes photodynamic therapy efficacyPhotodynamic therapy uses a light-activated drug to create reactive oxygen species that kill nearby cancer cells, but its use is limited by the low penetration of light into tissue and insufficient accumulation of the photosensitizing drug in tumors. Russian researchers have devised an MRI-based method to overcome this hurdle.January 23, 2019Clinical NewsMRI guidance is feasible for proton therapyMR guidance is emerging as a powerful tool for real-time monitoring of radiation treatments, offering excellent soft-tissue contrast and the ability to track intrafractional tumor motion. Hybrid devices for MR-guided photon-based radiotherapy are now in clinical use. But to date, no such combined system exists for proton therapy.December 20, 2018Artificial IntelligenceMachine learning can generate realistic breast phantomsDutch and Italian researchers have used machine-learning algorithms to generate "superresolution" digital breast phantoms. They are now working to develop dynamic contrast-enhanced dedicated breast CT, which may prove useful for many stages of breast cancer care.December 16, 2018Clinical NewsRadiotherapy is 'undervalued and needs greater investment'Radiotherapy is undervalued and needs greater investment, reports a white paper by the Marie Curie Legacy Campaign. The report was launched on 7 November to coincide with the anniversary of the birth of Marie Curie.November 8, 2018Clinical NewsNovel imaging method tracks brain shrinkageA research team from Greece and Italy has proposed the use of noninvasive time-resolved near-infrared measurements to track brain atrophy during disease progression. The new technique is fast and cheap and causes no harm, they said.October 18, 2018Clinical NewsIon-beam CT improves particle therapy planningA better option for particle therapy treatment planning would be to use protons or other ion beams. Instead of incorporating an error margin of around 3% as with x-ray CT images, ion CT provides a direct estimation of relative stopping power and eliminates conversion uncertainties.August 29, 2018Clinical NewsDual-energy CT proves optimal for proton planningProton therapy plans rely on estimates of particle range in the patient with the CT numbers converted into proton stopping-power ratios, but this approach limits treatment accuracy. Dual-energy CT can help determine particle range and calculate treatment plans, German research has found.May 20, 2018Previous PagePage 2 of 10Next PageTop StoriesUltrasoundSamsung Medison to acquire SonioSonio will remain an independent company headquartered in France, according to Samsung Medison.Womens ImagingHologic brings Brevera 7-gauge breast biopsy needle to EuropeNuclear MedicineITM appoints chief medical officerIndustry NewsSiemens reports revenue, profit gains in Q2Sponsor ContentJourney to the Cloud: A Snapshot of Market Progress - 22 May @ 7pm CET
