ABSTRACT
After a study on the characteristic of ECG data, we propose here in this paper a lossless compression method of ECG data, which is based on JPEG2000. It integrates both 1D and 2D compression. The method has been verified through all forty-eight records in MIT-BIH Arrhythmia database. And the result shows that the method has a better compression rate and a good computational efficiency.

This paper presents a method based on NLP to realize structuralization of digestive endoscopy reports. The method is taking advantage of existing NLP's processing technologies and introducing minimal standard terminology (MST) to transform a narrative gastroscopy report into the structuralization report based on MST, whose accuracy rate is 92.3%.

The positioning error in radiotherapy is one of the most important factors that influence the location precision of the tumor. Based on the CT-on-rails technology, this paper describes the research on measuring the positioning error in radiotherapy by comparing the planning CT images with the treatment CT images using 3-dimension (3D) methods. It can help doctors to measure positioning errors more accurately than 2D methods. It also supports the powerful 3D interaction such as drag-dropping, rotating and picking-up the object, so that doctors can visualize and measure the positioning errors intuitively.

This paper presents a typical Clinical Information System for ICU and its design and implementation. This system is able to capture and archive vital data from the monitor network, providing a whole digital solution in ICU. These vital data can be used in quantitative analysis in the computer-assisted decision support.

Because of different display parameters and other factors, digital medical images present different display states in different section offices of a hospital. Based on CPI integration profile of IHE, this paper implements the consistent presentation of medical images, and it is helpful for doctors to carry out medical treatments of teamwork.

PACS (Picture Archiving and Communication System) is successfully applied in Huzhou Central Hospital, and is well integrated with its HIS system by WEBSERVICE middleware. The system supports DICOM 3.0 Standard, and DICOM gateways are installed for modalities that do not support DICOM so as to have implemented the digitalization of all the image departments in the hospital.
