Locations means (row, columns) or (y, x). If you want both of those separately you'll need an array or two vectors. If you want one you'll have to use linear indexing as Dishant showed you.

% Use Linear Indexing/Vector Indexing
ind = 1:M*N; % For an image of dimension MxN

[rows, columns, numberOfColorChannels] = size(yourImage);
[X, Y] = meshgrid(1:columns, 1:rows);
xy = [X(:), Y(:)];
I really highly doubt you'd ever need this. Explain to me why you think you need this and I'll explain why you probably don't.

Yeah, like I thought, you don't want what you asked for. Even if you did you'd use
elementsToTake = randperm(numel(grayImage), 0.15*numel(grayImage));
But that's going to take random pixels, not random rays from your ultrasound image.
