ABSTRACT:
A diagnostic imaging system is comprised of a plurality of linearly adjustable functions and a plurality of binary selectable functions which are controlled by a multi-function joystick controller. The controller has a plurality of function select switches, a joystick, a mushroom cap rotatably engaged on the joystick, a microprocessor, a plurality of switches individually engageable by pivoting the joystick and a pair of switches individually engageable by clockwise or counterclockwise rotation of the mushroom cap. The switches and the microprocessor cooperate such that the selection of a first function select switches causes the operation of the joystick switches and/or mushroom cap switches to be linked to a predetermined first set of imaging system functions. Subsequently, when a second function select switches is selected the joystick switches and mushroom cap switches thereafter operate a predetermined second set of imaging system functions until another function select switch is selected.
