An adaptive-gain alpha-beta tracker combined with three-dimentional circular prediction using estimation of the plane state
In tracking systems using phased array antenna, the adaptive-gain CX-P tracker combined with circular prediction has been proposed for maneuvering targets. However, tracking quality of the circular prediction filter degrades for highly maneuvering targets that continue to change the turning plane, since the circular prediction is calculated on the assumption that a target flies on the same plan...
متن کاملThin slice three dimentional (3D) reconstruction versus CT 3D reconstruction of human breast cancer
BACKGROUND & OBJECTIVES With improvement in the early diagnosis of breast cancer, breast conserving therapy (BCT) is being increasingly used. Precise preoperative evaluation of the incision margin is, therefore, very important. Utilizing three dimentional (3D) images in a preoperative evaluation for breast conserving surgery has considerable significance, but the currently 3D CT scan reconstruc...

متن کاملAutomated Scan Plane Planning for Brain MRI using 2D Scout Images
Introduction Automated scan plane planning is expected to provide consistent scan plane prescriptions and to improve MRI scanner usability. Consistent scan planes are useful for follow-up examinations. The typical workflow of a scan plane setup requires careful manual positioning, and it suffers from inter-operator variability. Furthermore, having to perform a scan plane setup for each examinat...
متن کاملCT scout z-resolution improvement with image restoration methods
Currently, new applications demand utilizing CT scout images for diagnostic purposes. However, many CT scout images cannot be used diagnostically due to their poor resolution, particularly in the direction of table movement. Spatial resolution generally can be improved with image restoration techniques. Based on the principles of Wiener filtering and inverse filtering, this paper presents a mod...
