Liquid fiducials offer precision radiotherapy

Fiducial markers used in radiation therapy come in various shapes and sizes; but until now, all were solid structures. Danish start-up company Nanovi has now developed a liquid fiducial – BioXmark – that can be injected via thin needles directly into the tumour site. Following CE Mark approval last month, Nanovi commercially launched its novel liquid soft-tissue marker at last week’s ESTRO 35 meeting in Turin, Italy.
