Managing one’s mental workload is a tricky balancing act that can affect cognitive performance and decision making abilities. Too little engagement with an ongoing task can lead to boredom and mistakes; too high could cause a person to become overwhelmed. For those performing safety-critical tasks, such as air traffic controllers or truck drivers for example, monitoring how hard their brain is working is even more important – lapses in focus could have serious consequences.

ThinkQA Secondary Dose Check software provides quality assurance for every fraction of adaptive radiotherapy without impacting the clinical workflow Adaptive radiotherapy, an advanced cancer treatment in which each fraction is tailored to the patient’s daily anatomy, offers the potential to maximize target conformality and minimize dose to surrounding healthy tissue. Based on daily scans – such as MR images recorded by an MR-Linac, for example – treatment plans are adjusted each day to...

Proton therapy is a highly effective and conformal cancer treatment. Proton beams deposit most of their energy at a specific depth – the Bragg peak – and then stop, enabling proton treatments to destroy tumour cells while sparing surrounding normal tissue. To further optimize the clinical treatment planning process, there’s recently been increased interest in considering the radiation quality, quantified by the proton linear energy transfer (LET).

A new retinal stimulation technique called Oz enabled volunteers to see colours that lie beyond the natural range of human vision. Developed by researchers at UC Berkeley, Oz works by stimulating individual cone cells in the retina with targeted microdoses of laser light, while compensating for the eye’s motion. Colour vision is enabled by cone cells in the retina.

THERYQ is developing a radiotherapy system that uses very high-energy electrons to treat deep-seated tumours, and can also enable FLASH treatments Electron therapy has long played an important role in cancer treatments. Electrons with energies of up to 20 MeV can treat superficial tumours while minimizing delivered dose to underlying tissues; they are also ideal for performing total skin therapy and intraoperative radiotherapy. The limited penetration depth of such low-energy electrons,...
