PHILIPS LINEAR ACCELERATOR

 
 
Hoag Memorial Hospital Presbyterian Newport Beach, California
 
 
 

PROBLEM - The space available for this addition was extremely limited, both in terms of the floor area as well as the vertical clearances. The floor area was substantially less than is normally needed for this type of treatment room. In addition, a major mechanical duct run and the chilled water system piping passed through this space.

SOLUTION - In order to make the limited available space workable, the thickness of the shielding walls was reduced by utilizing a series of fifty-three one-inch thick steel plates placed within the concrete walls of the vault, the shielding thickness along the primary beam was greatly reduced. In addition a two door short maze was designed to allow the medical staff more rapid access to the maze and treatment room. This $1.2 million project was designed around the Philips SL25, a high-energy dual X-ray mode accelerator. Through the use of subdued lighting, carefully detailed casework and warm colors, an understated image was achieved consistent with the theme of this facility.
