BACKGROUND AND PURPOSE Surgical stapling devices are often used to secure the distal ureter along with a cuff of bladder during laparoscopic nephroureterectomy. As the viability of cells within the stapled tissue would be important in patients with upper urinary-tract transitional-cell carcinoma, we determined the viability of cells within the lines of(More)
BACKGROUND AND PURPOSE The effect of stents on ureteral peristalsis in vivo is not entirely clear. We sought to develop a minimally invasive method for its study. MATERIALS AND METHODS In female domestic pigs, electrical potentials from the ureter were measured by bipolar steel-wire electromyography electrodes delivered laparoscopically. Mechanical(More)
In this paper, we solve the pose estimation problem in real time using multiple nonoverlapping cameras and the Extended Kalman Filter (EKF). Four cameras arranged in two back-to-back pairs are put on the platform of a moving robot. The two axes passing through the camera centers of each pair are perpendicular. This arrangement aims to maximize the benefits(More)
Image compression is one of the most important topics in the field of digital image processing. JPEG2000 is considered as a new image compression standard that offers the requirements needed nowadays. Efficient hardware implementation of this complex standard is a considerable challenge in order to embed the compression engine inside the imaging devices. MQ(More)
