by Nathan Howes Special to the Beaver SickKids radiologist speaks to uses of 3D imaging in medicine Health 15 | Thursday, February 6, 2014 | OAKVILLE BEAVER | www.insideHALTON.com "Connected to your Community" Medical professionals can save time and lives thanks to 3D technology, says the head of cardiac imaging at the Hospital for Sick Children (SickKids). Dr. Shi-Joon Yoo, a cardiac radiologist and founder of 3D Hope Medical, recently made a presentation on the bene ts of 3D printing in medicine at Javelin Technologies in Oakville. "A good image saves a thousand words. A good model saves a thousand images. A good model saves a million words," he said. Located on Superior Court, Javelin Technologies is a Canadian expert in 3D design and has serviced thousands of companies with solutions for design, data management and 3D printing. Yoo spoke about using rapid prototyping for cardiovascular surgery and patients with congenital heart disease. His address was preceded by a tour, showcasing 3D printing, 3D virtual reality and 3D design software. Yoo noted there are numerous types of machinery used in 3D printing, including selective la- Dr. Shi-Joon Yoo, a cardiac radiologist at SickKids, was at Oakville's Javelin Technologies recently to discuss the bene ts of 3D imaging in medical applications. | photo by Riziero Vertolli ­ Oakville Beaver (Follow on Twitter @ halton_photog or facebook.com/HaltonPhotog) ser sintering (SL), electron beam melting (EBM), inkjet technology, stereolithography (STL), fused deposition modeling (FDM), laminated object manufacturing (LOM) and 3D microfabrications. "Among these, I nd the EBM and inkjet technologies are directly applicable to medicine. The EBM is very attractive in medicine," said Yoo, noting it is one of the "best possible options" in hip replacement cases. To make the imaging "as good as possible" for rapid-prototype models, information that is needed must be sorted and selected through a segmentation process, he said.

Walking down the aisles of the store, it's quickly apparent that the choices of lotions and potions to stop dry skin are endless, but which product should you choose? There's one superfood solution that is inexpensive, works wonders, and will perhaps make you think you're on a tropical island; coconut oil, the perfect product to help ward off the attacks of Canada's harsh winters. "Coconut oil has increasingly gained popularity in Canada, and for good reasons. Its multiple uses are impressive, but most importantly, it is a truly remarkable skincare product," says Helen Sherrard, president of the Canadian Health Food Association (CHFA). "It is a known fact that winter can wreak havoc on the skin. Adding coconut oil to your skincare routine is a particularly good way of protecting yourself against the damages of bitterly cold winds and dry indoor conditions." Coconut oil is rich in medium-chain fatty acids, which allows it to retain the moisture content of the skin while helping it to look and feel silky smooth. It also has high quantities of vitamin E; an essential nutrient for healthy skin growth, repair, and the prevention of premature aging. Coconut oil is also rich in many proteins that contribute to cellular health and tissue repair. CHFA recommends that you winter-proof your skin with coconut oil by using it in the following ways: Moisturizer: simply rub a small amount of coconut oil wherever you have dry or cracked skin. Your skin will absorb the oil quickly, plus it smells wonderful. Exfoliant: making your own natural exfoliant by mixing coconut oil with natural exfoliating substances like sea salt or sugar is a great way to remove dead cells. Lip balm: applying chemical products on your lips is a sure way to ingest potentially harmful substances. Substitute your chemical lip balm for coconut oil and keep your lips moist and protected throughout the winter.
