Philips Medical Systems (Booth #1637) is featuring its Brilliance CT Big Bore Oncology configuration. The scanner is designed specifically for radiation treatment planning, and is in use at luminary clinical sites around the world.  

The Brilliance Big Bore offers a 60cm scan true field of view, providing accuracy in geometry and superior uniformity that is otherwise lost outside this field of view. The 60cm true scan field of view and 24 mm coverage with every rotation allows clinicians to measure body mass and more accurately target the location and size of tumors. This increased visualization improves accuracy in delivering targeted therapy to tumors and also reduces harm to surrounding healthy tissue. The larger coverage area is designed to improve the ability to isolate the area of treatment without being hindered by patient position or tumor location.
In addition, Philips CT localization (CT L.O.C.) application is found directly on the console, allowing clinicians to localize the tumor and mark the patient for therapy delivery without leaving the console. 

Working with its customers, Philips also has developed the new correlated respiratory imaging which allows the user to track a patient's breathing to visualize tumor motion to minimize motion artifacts, the company said.
