Newton Medical Center could soon be getting a $1.75 million da Vinci Si Robotic Surgery System and that could mean safer, quicker surgeries and shorter recovery times as well as less money spent by patients. The Georgia Department of Community Health issued a certificate-of-need for the da Vinci system to NMC on March 16; this certificate is required for all hospital purchases of more than $1 million. Devices like CT and MRI scanners also require these certificates.The certificate does not mean the state will provide any financial assistance; NMC will have to pay the entire $1.75 million,
