JSRT (Japanese Society of Radiological Technology Database)

The standard digital image database with and without chest lung nodules (JSRT database) was created(*1) by the Japanese Society of Radiological Technology (JSRT) in cooperation with the Japanese Radiological Society (JRS) in 1998. Since then, the JSRT database has been used by a number of researchers in the world for various research purposes such as image processing, image compression, evaluation of image display, computer-aided diagnosis (CAD), picture archiving and communication system (PACS), and for training and testing.

・Useful for ROC analysis (154 nodule and 93 non-nodule images)

・ High resolution (2048 x 2048 matrix size, 0.175mm pixel size)

・ Wide density range (12bit, 4096 gray scale)

・ Universal image format (no header, big-endian raw data)

・ Useful for diagnostic training and testing

・ Additional information: patient age, gender, diagnosis (malignant or benign), X and Y coordinates of nodule, simple diagram of nodule location, degree of subtlety in visual detection of nodules
