Fine Alnico 8 spherical powder produced by gas atomization was consolidated through hot pressing (HP), hot isostatic pressing (HIP), and compression molding and subsequent sintering (CMS) techniques. The effects of different fabrication techniques and processing parameters on microstructure and magnetic properties were analyzed and compared. The HP, HIP, and CMS magnets exhibited different features...
Recent concern for supply and price of rare earth (RE) metals has stimulated the search for alternative magnets [1]. Alnico is an attractive non-RE magnet alloy due to its excellent magnetic stability. However, the best energy product (BH)max of the magnets is only about 10 MGOe. A key to improving the magnetic properties is to enhance coercivity Hci by optimizing composition and microstructure [2]...
One important property of a registration solution is inverse consistency. While often overlooked, this property is critical in many medical applications, including radiation-therapy treatment planning and unbiased atlas-construction. In this paper, we propose a novel extension to the graph-based random walker image registration (RWIR) algorithm to ensure its inverse consistency. In contrast to many...
Objectives To measure the performance characteristics of combined T2-weighted (T2W) and diffusion-weighted (DW) magnetic resonance imaging (MRI) suspicion scoring prior to MR-transrectal ultrasound (TRUS) fusion template transperineal (TTP) re-biopsy. Methods Thirty-nine patients referred for prostate re-biopsy, with prior MRI examinations, were retrospectively included. The MR images, including...
