Such calculations allow surgeons to preserve as much of a patient’s heart anatomy as possible and limit implanted prosthetic materials. “It’s a difference-maker to be able to say, ‘For this child, the valve leaflet needs to be lengthened by four millimeters here and two millimeters there so we can create a perfectly-shaped patch.’” New viewpoints to help surgeons and parentsĪ surgeon’s experience of knowing how to approach treatment still matters, Hoganson says, but 3D modeling lets them create specific treatment plans for each individual. With those perspectives, Hoganson and his surgical team had a precise plan that let them reconstruct the aorta and restore function to the ventricle. That weakened the left ventricle and limited the pumping of oxygenated blood throughout her body. They create a model by uploading a still frame of a patient’s cardiac CT scan or MRI to the software. Or a bunch of those images can be stacked to create a movie that shows the heart beating, says physician scientist Reena Ghosh, MD, one of the team members who creates the models.īy deleting the many parts seen in the digital model on the left, the surgical team was able to focus closely on a congenital narrowing in a patient’s aortic arch prior to repair.Īfter they made a pulmonary artery disappear from the screen, they could see the transverse arch of her aorta was narrow. The team has since created more than 800 patient-specific 3D models. Finding the right 3D angle for a newborn’s surgery That perspective, combined with computer simulations of the teen’s circulation, helped them shape the design of a form-fitting cuff to repair his heart. One of the earliest cases run through the software let them see the precise size and layout of a complex reconstruction of an 18-year-old’s heart. In other words, simulation and engineering tools used to develop airplane wings could now illustrate how to treat complex heart disease. That work took a significant step forward when the team incorporated 3D modeling software that’s used by aerospace and automotive engineers into their calculations.

Knowing with near-certainty what to expect eliminates guesswork in the operating room.” That lets us better understand defects and possible repair options. “You can see the details of the heart within the pumping chambers and the vessels around the heart. “People think in 3D, so to see the heart this way before surgery is transformational,” says David Hoganson, MD, a cardiac surgeon and co-leader of the team behind the modeling. Now, 3D modeling allows them to capture a comprehensive view of a child’s heart before surgery and plan the most effective repair procedure. One of the most important tools for complex heart surgeries at Boston Children’s isn’t even in the operating room.įor years, heart surgeons couldn’t see the complete extent of a patient’s condition until a procedure started, forcing them to rely on experience, diagnostic imaging, and other information to plan surgery.

In 2016, the photographer was accused of rape by four separate women who had served as former models. Similar to the work of Jock Sturges and Sally Mann, Hamilton’s erotic subject matter caused complaints of indecency over the decades. He published numerous photobooks during his life, The Age of Innocence (1995) being one of his most popular. In 1979, his film Laura was released in France-the movie blends melodrama with soft-core pornography, as wells as Hamilton’s hallmark soft focus. Born on Apin London, United Kingdom, the artist initially found work as an art director, then a commercial photographer in the 1950s and 60s in France. Using a photographic technique akin to painting, he has acknowledged the influence of Lucas Cranach on his style. Often controversial, the images evoke an effect of dreaminess through soft focus and varied grain. David Hamilton was a British photographer and film director known for his nude photographs of adolescent girls.
