Abstract
Abstract An apparatus and method for producing an image of the brain by ultrasonic scanning, wherein brain metabolism is measured and displayed by monitoring amplitudes of localized changes of intracranial interfaces uses a flexible array applied to the scalp overlying the skull to produce a superposed grey scale image representing static structures and a color-coded pattern representing motion information.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
87 words
A method for producing an image of a human brain in a skull that indicates location and magnitude of brain motion, comprising the steps of: providing a transducer array that conforms to the skull; coupling energizing signals to said transducer array to produce transmitted ultrasonic energy; receiving reflected ultrasonic energy at said transducer and producing receiver signals; storing receiver signals to obtain stored signals; producing a motion signal as a function of the difference between said receiver signals and said stored signals; and displaying said motion signals.
Claim 2
Independent Claim
87 words
A method for producing an image of a human brain in a skull that indicates location and magnitude of brain motion, comprising the steps of: providing a transducer array that conforms to the skull; coupling energizing signals to said transducer array to produce transmitted ultrasonic energy; receiving reflected ultrasonic energy at said transducer and producing receiver signals; storing receiver signals to obtain stored signals; producing a motion signal as a function of the difference between said receiver signals and said stored signals; and displaying said motion signals.
Claim 3
Dependent Claim
33 words
The method as defined by claim 1, wherein said displaying step comprises quantifying the amplitude of motion represented by said motion signals to produce motion amplitude signals, and displaying said motion amplitude signals.
Claim 4
Dependent Claim
33 words
The method as defined by claim 2, wherein said displaying step comprises color coding said motion amplitude signals with different colors for different motion amplitudes, and displaying said color coded motion amplitude signals.
Claim 5
Dependent Claim
13 words
The method as defined by claim 2, further comprising displaying said receiver signals.
Claim 6
Dependent Claim
18 words
The method as defined by claim 4, wherein said motion signals and said receiver signals are displayed together.
Claim 7
Dependent Claim
17 words
The method as defined by claim 5, wherein said receiver signal is displayed as a luminance signal.
Claim 8
Dependent Claim
13 words
The method as defined by claim 1, further comprising displaying said receiver signals.
Claim 9
Dependent Claim
18 words
The method as defined by claim 7, wherein said motion signals and said receiver signals are displayed together.
Claim 10
Dependent Claim
17 words
The method as defined by claim 8, wherein said receiver signal is displayed as a luminance signal.
