Abstract: Methods and related computational techniques are presented for analyzing images from various scan modalities, such as computerized tomography (“CT”). The methods convert image values to relative differences, to highlight side-to-side asymmetry. The conversion may be performed by comparing a small region of the scan to the corresponding region in the contralateral hemisphere, quantifying the degree of relative difference using statistical techniques, and representing this quantity of relative difference in a two dimensional or three dimensional relative difference map. In exemplary embodiments the method involves assigning an axis or plane of symmetry to a medical image, computing, using the image data, at least one relative difference map based on a comparison of two substantially symmetrical areas around the axis of symmetry, and generating a representation of any relative difference between the two symmetrical areas.

Abstract: A method and related software are provided for analyzing images such as computerized tomography images obtained from a standard perfusion CT software package. This method converts image values to relative differences, which represents meaningful side-to-side asymmetry. This conversion may be performed by comparing a small region of the scan to the corresponding region in the contralateral hemisphere, quantifying the degree of relative difference using statistical techniques, and representing this quantity of relative difference in a two dimensional or three diemnsional relative difference map.

Abstract: An improved waistband construction for garments including a new one-piece flat elastic strip having middle and lower portions of different stretchability and a lip portion integral with the middle portion which extends above the edge of the middle portion and has a stretchability between the stretchability of the middle and lower portions of the elastic strip.

Abstract: An improved waistband construction for garments including a new one piece flat elastic strip having upper and lower portions of different stretchability. The elastic strip is connected to the fabric of the waistband and the shell of the garment so as to allow more expansion and comfort in fitting multiple sizes.
