We present a novel low-cost device for scanning object surfaces based on structured LED (Light Emitting Diode) light and a single, monocular image from a standard machine vision camera. During the calibration phase we find the displacement of the imaged LED-projected marker points as a function of depth. Using this displacement data and a suitable(More)
The design, and complications seen during the first 2 years, of a randomized trial of postoperative radiotherapy for rectosigmoid cancer Dukes' B and C are presented and discussed. It is concluded that the present complication rate-below 10% in 221 patients-permits continuation of the intake, which is planned to include 550 patients, to demonstrate a(More)
The prognostic value of several clinical and histopathological characteristics has been evaluated in patients with Dukes' B and C carcinoma of the rectum and the rectosigmoid. Data on 260 Dukes' B and 208 Dukes' C tumours entered into a prospective, randomized clinical trial of post-operative radiotherapy (50 Gy given with 2 Gy/fraction in an overall time(More)
Factors influencing time to loco-regional recurrence were identified in a multivariate regression analysis of data from a series of 468 radically operated patients (260 Dukes' B and 208 Dukes' C) with carcinoma of the rectum and the rectosigmoid. A number of clinical and pathological characteristics were prospectively collected and recorded. In addition,(More)
In this article we give a description of the scope and objectives of the RoBlock project [1]. The RoBlock project is an interdisciplinary research project within the area of intelligent manufacturing systems. The purpose of the project is to develop a platform usable for demonstration of how state-of-the-art technology and methods can be combined to make(More)
