Dynamic Contrast-Enhanced MR Imaging in the Evaluation of Patients with Prostate Cancer
ABSTRACT Prostate cancer is a common tumor among men, with increasing diagnosis at an earlier stage and a lower volume of disease because of screening with prostate-specific antigen (PSA). The need for imaging of the prostate stems from a desire to optimize treatment strategy on a patient and tumor-specific level. The major goals of prostate imaging are (1) staging of known cancer, (2) determination of tumor aggressiveness, (3) diagnosis of cancer in patients who have elevated PSA but a negative biopsy, (4) treatment planning, and (5) the evaluation of therapy response. This article concentrates on the role of dynamic contrast-enhanced MR imaging in the evaluation of patients who have prostate cancer and how it might be used to help achieve the above goals. Various dynamic contrast enhancement approaches (quantitative/semiquantitative/qualitative, high temporal versus high spatial resolution) are summarized with reference to the relevant strengths and compromises of each approach.

Conference Paper: A computer-based training environment for forestry telemanipulation[Show abstract] [Hide abstract]
ABSTRACT: Forestry machines are essentially four degree of freedom electrohydraulic telemanipulators equipped with specialised end-effectors for harvesting trees. In this paper, we describe forestry telemanipulation and then review the development of a computer-based training aid based on graphical simulation. To the best of our knowledge, our work here represents the first concentrated attempt at developing a system intended to become an integral part of forestry machine operator trainingIntelligent Robots and Systems, 1997.
