Sometimes, Dr. Rose Ganim, chief of thoracic surgery at Baystate Medical Center in Springfield, lies awake at night contemplating the best approach for a complex operation.
When it comes to surgery, Ganim said, good planning can be the difference between life and death. And that makes getting an accurate picture of what’s going on beforehand imperative.
But even the most technologically advanced MRI and CAT scan machines produce only flat-layered images of what she’ll see in the operating room, and Ganim’s knowledge of human anatomy is all she has to turn over in her mind.
Replica organ models, however, like those printed by biomedical engineer Greg Gagnon in an office in Baystate’s intensive care unit, can get her as close to reality as possible without actually cutting a patient open. Single-handedly — with support from the hospital’s administration — Gagnon, who is entirely self taught, is changing the way Baystate surgeons plan for their work.
“This kind of modeling helps me to sleep better, because I can imagine it much more easily,” Ganim said. Sitting at a table in her Springfield office, she picked up a plastic replica of a large tumor on a patient’s ribcage compressing the right lung.
“On the CAT scan, it wasn’t really clear what was going on,” Ganim said. She sent the scans to Gagnon, who used software to convert the layered images into a 3-dimensional model, isolate the tumor, rib cage and lungs, and print a replica, to scale, using three types of plastic to distinguish the different elements.
“It was a great illustration, and I was surprised how much more clear things were for me,” Ganim said.
During the surgery, the doctor was able to remove the whole tumor, solidifying 3-D printing as a routine way for her to plan for complex surgeries and educate her patients.

Instagram Makes Teen Accounts Private as Pressure Mounts on the App to Protect Children- Instagram is making teen accounts private by default as it tries to make the platform safer for children amid a growing backlash against how social media affects young people's lives.
Instagram is making teen accounts private by default as it tries to make the platform safer for children amid a growing backlash against how social media affects young people's lives. The teen accounts will be private by default. Private messages are restricted so teens can only receive them from people they follow or are already connected to. Sensitive content, such as videos of people fighting or those promoting cosmetic procedures, will be limited, Meta said. Teens will also get notifications if they are on Instagram for more than 60 minutes and a sleep mode will be enabled that turns off notifications and sends auto-replies to direct messages from 10 p.m. until 7 a.m.
