Quantitative medical image analysis of musculoskeletal system

Joint Disease Workshop – Quantitative Automated Musculoskeletal Analysis

In clinical studies of osteoarthritis using magnetic resonance imaging, the placement of the test subject in the scanner tends to vary and this can a ect the outcome of automatic image analysis methods for articular cartilage assessment, particularly in multi-center studies. We have developed an automatic iterative method that corrects for position variations by combining the two steps: shiftin...

Analysis of security problems in a medical image encryption system

Recently, a new system for the secure transmission and efficient storage of medical images interleaved with patient information has been proposed in 2003 by Rajendra Acharya et al. In this paper, we analyse the security of this system, showing how to improve it to obtain a truly secure system.

Automating Medical Image Analysis

By image analysis we mean the operation of extracting a relativeiy small amount of quantitative information from a two-dimensional image. Typically, a two-dimensional image, in digital form, consists of an array of 512 x 512 eight-bit digital words. The quantitative information to be extracted consists of a few thousand digital words. These words may describe, for example, the contours of cell ...

Advanced Medical Image Analysis

Medical image analysis is performed in order to facilitate medical research and ultimately provide better healthcare. It is critical to the advancement of imaging-based medical research, for example, using magnetic resonance (MR) imaging to probe brain structural and functional changes related to a disease or cognitive process. This special issue highlights new methods of signal and image proce...
