A newly-approved community diagnostics centre will aim to offer patients quicker diagnosis by carrying out thousands of extra tests every year.
The facility at Mansfield Community Hospital plans to offer patients across Nottinghamshire a "one-stop-shop" for treatments.
Mansfield District Council approved the plans earlier this week.
NHS bosses said it would be able to offer earlier access to MRIs, X-rays, ultrasounds and CT scans.
Sherwood Forest Hospitals NHS Trust said it could also lead to the creation of hundreds of new jobs.
The unit will replace the annexe on the Stockwell Gate hospital site, which is due to be demolished.
The facility will be partly funded by £24.2m which Nottingham and Nottinghamshire Integrated Care Systems has been allocated to build diagnostic centres.
The remaining sum will be spent on a large facility in Nottingham city centre, run by Nottingham University Hospitals NHS Trust, according to the Local Democracy Reporting Service.
