A new state-of-the-art MRI suite will be installed at the hospital in Louth after locals raised over £500,000.
It took people well over a decade to get the money together after an appeal by the town’s former mayor in 2004.
Work is now about to start on transforming a former laundry building into the MRI suite in a project that will cost £850,000 overall.
United Lincolnshire Health Trust provided the other £350,000.
As well as the scanner, there will be new clinical rooms and waiting areas for both outpatients and inpatients.
It is expected that the scanner will be used by 8,000 patients a year.
Trevor Marries, who started the appeal as mayor, said: “Earlier this we heard the fantastic news that the appeal had been a success.
“It’s taken us many years to get where we are and I cannot wait to see work get underway to transform this building.”
