It seems the files are binary files. You need to use fread to read the data. But you need to know the format of the file.

Like KSSV says, use fread()
fid = fopen('YourProjection (1).sin','r');
A = fread(fid,Inf,'*uint16');
fclose(fid);
A = reshape(A,512,[]).';
imshow(A,[])
fid = fopen('point2.a00','r');
A = fread(fid,Inf,'*uint16');
fclose(fid);
A = permute(reshape(A,512,512,[]),[2 1 3]); % there are 8 pages
imshow(A(:,:,1),[])

You need both the header file (HDR) and the image file (IMG). The HDR file contains no image data. You should be able to use the interfile reading tools:
