Colleagues,

New CAD tool follows lung nodules over time
Kensaku Mori, Ph.D., and colleagues from Nagoya University in Nagoya, Japan are creating and combining algorithms for object detection, classification, measurement, registration, and the like, the researchers have created a rather ambitious computer-aided detection (CAD) scheme that finds, names, measures, and color-codes each nodule, highlighting any changes from previous scans in a rainbow of complementary colors.
At present, the system is not ready for clinical use ... But the "automated analysis and visualization system" fulfills a critical need that other CAD schemes have not ...
... Many scans, little time ... CT chest scans are everywhere these days, used for lung cancer screening, surgical planning, and follow-up of metastases postchemotherapy ... Following the lung lesions of so many patients in three dimensions plus time isn't just a challenge for doctors, but for all CAD systems ... The algorithm allows radiologists to easily monitor follow-up scans based on nonrigid registrations of CT chest images ... It coregisters follow-up CT scans and finds corresponding nodules that are automatically detected from each CT scan. The results are then displayed using dynamic volume rendering with changing volumes...
