Illustration of the considerations for apparent resolution for (a) a traditional radiological display and (b) virtual reality visualization. The effect of distance and scale in a virtual reality visualization is illustrated in (c). In all cases shown, the medical image is composed of a fixed number of pixels as shown by the gray grid on top of the heart. As shown in (c), depending on how far or close the user is to the heart in the virtual environment, the number of pixels used to render the heart is different (the vertical screen is always near the eyes)
