The Art For Life project, which is part of a wider NHS scheme, is now incorporating a 24m wall to give artists’ work an even greater platform at the hospital.
The wall links the Queen’s Building to the Jubilee Building.
Digital prints by Esther Rolinson are the first artworks to be displayed in the extended gallery.
Her work is a combination of delicate, painstakingly drawn observations of plants and tree roots among other abstract drawings.
Art for Life curator Sara Dudman said the team was “delighted” with the latest enhancements.
“We know what a difference our exhibitions make to staff, patients and visitors to the hospital by uplifting the environment and experience of being here,” she said.
