My Lords, I thank the Minister for her response to my valedictory Question, and indeed all other colleagues, who have been generous—overgenerous, I would say—in their remarks on my retirement.

I also thank the Minister for her response, which is very encouraging. Focused ultrasound is a non-invasive technology capable of both imaging and actual treatment, with the potential to treat a wide range of conditions, including less survivable cancers and brain diseases. What are the Government doing to pursue the massive potential improvements offered by focused ultrasound—for example, in the treatment of malignant brain tumours, as demonstrated to the noble Lord, Lord Vallance of Balham, at a recent Royal Society summer science exhibition? How will the Government seek to promote further research and development for this important technique to catch up with other countries, which I am sorry to say are ahead of us, so that more UK patients can benefit from it?
