Abstract
Abstract An improved still or frozen picture is provided in an ultrasonic sector scanner by generating and displaying two frames. The first frame is identical to the frame generated for dynamic real-time display. The second frame is generated from vectors lying intermediate vectors of the first frame with the same reflected signal data applied thereto. Accordingly, the pixel data is doubled in the still or frozen picture.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
67 words
In an ultrasonic sector scanner, a method of providing an improved frozen video display comprising the steps of generating first pixel data for a first frame from reflected ultrasonic data for a first plurality of vectors generated by said sector scanner, and generating second pixel data for a second frame from said reflected data for a second plurality of vectors lying intermediate said first plurality of vectors.
Claim 2
Dependent Claim
67 words
In an ultrasonic sector scanner, a method of providing an improved frozen video display comprising the steps of generating first pixel data for a first frame from reflected ultrasonic data for a first plurality of vectors generated by said sector scanner, and generating second pixel data for a second frame from said reflected data for a second plurality of vectors lying intermediate said first plurality of vectors.
Claim 3
Dependent Claim
70 words
In an ultrasonic sector scanner in which pixel data for a display are generated from input data based on a plurality of vectors, apparatus for improving a freeze frame display comprising means for generating a second plurality of vectors which are intermediate said first plurality of vectors, and means for generating second pixel data for a second frame based on said second plurality of vectors and said reflected ultrasonic data.
Claim 4
Dependent Claim
70 words
In an ultrasonic sector scanner in which pixel data for a display are generated from input data based on a plurality of vectors, apparatus for improving a freeze frame display comprising means for generating a second plurality of vectors which are intermediate said first plurality of vectors, and means for generating second pixel data for a second frame based on said second plurality of vectors and said reflected ultrasonic data.
Claim 5
Dependent Claim
54 words
Apparatus as defined by Claim 2 wherein said means for generating a second plurality of vectors comprises means for averaging the start point and angle of inclination of adjacent vectors of said first plurality of vectors thereby obtaining vectors in said second plurality of vectors which lie intermediate adjacent vectors of said first plurality.
