As part of the 2015 SPIE Medical Imaging Conference, SPIE – with the support of American Association of Physicists in Medicine (AAPM) and the National Cancer Institute (NCI) – will conduct a “Grand Challenge” on quantitative image analysis methods for the diagnostic classification of malignant and benign lung nodules. The LUNGx Challenge will provide a unique opportunity for participants to compare their algorithms to those of others from academia, industry, and government in a structured, direct way using the same data sets.
Release date of calibration set cases with truth: November 21, 2014
Release date of test set cases without truth: January 9, 2015
Submission date for participants to submit test set classification results: February 6, 2015
SPIE Medical Imaging meeting: February 21 to 26, 2015
