This database was made possible by a collaboration between the ELCAP and VIA research groups. It was created to make available a common dataset that may be used for the performance evaluation of different computer aided detection systems. This database was first released in December 2003 and is a prototype for web-based image data archives.

The database currently consists of an image set of 50 low-dose documented whole-lung CT scans for detection. The CT scans were obtained in a single breath hold with a 1.25 mm slice thickness. The locations of nodules detected by the radiologist are also provided.

The website provides a set of interactive image viewing tools for both the CT images and their annotations. All images and their annotations may be downloaded from the website.

We use a secure access method for the data entry web site to maintain the privacy of the data and the user. Currently, we have a self-certified web site, this causes most browsers to produce a number of warning messages. Please ignore these messages and click on the next, finish, accept or allow buttons as appropriate until the data entry web page appears. At this time the lock icon will appear on the web browser and transactions will be secure (in spite of all those messages).
