  • Patent number: 6757442
    Abstract: A technique is disclosed for enhancing discrete pixel images. Image enhancement is first performed by separating structural regions from non-structural regions and performing separate smoothing and sharpening functions on the two regions. Non-uniform equalization is then performed to reduce differences between high and low intensity values, while maintaining the overall appearance of light and dark regions of the reconstructed image. Contrast enhancement is then performed on the equalized values to bring out details by enhancing local contrast.

  • Patent number: 6675135
    Abstract: A method to be used during a product development procedure wherein the procedure includes a series of consecutive development phases and the product includes at least two critical to quality characteristics (CTQs). The method is for generating a confidence matrix which can be used to increase a product sigma through product design. A user initially provides product limits and thereafter provides additional development information during each consecutive development phase. During at least two of the development phases and for each CTQ, development information is used to determine a quality factor which is indicative of the probability that the product will be within the specified limits. Also, for each CTQ, a confidence factor is identified which is indicative of the probability that the quality factor is accurate. Then, quality factors, CTQs and confidence factors are arranged such that the CTQs and factors are correlated.

  • Patent number: 6661229
    Abstract: An RF birdcage coil for use in MRI systems is disclosed. A number of slotted or nonconductive channels are provided in the conductive material of the RF coil to minimize the size of the conductive paths available for eddy currents. Furthermore, blocking capacitors are applied between the legs and the end segments of the conductive elements to isolate the end segments from the legs at low frequency harmonics, such as those associated with eddy currents, while acting substantially as a short circuit at high operational frequencies. Preferably, the blocking capacitors are constructed by providing the legs of a plurality of I-beams on a first side of a dielectric material, and the end segments on an opposing side. The blocking capacitor results from overlapping the conductive material forming the leg and end segment on opposite sides of the dielectric material.
