Accumetra Publishes Method That Predicts The Bias and Precision Performance of CT Lung Nodule Volume Measurements
Lung imaging researchers from Accumetra, Mount Sinai, and Cleveland Clinic published a manuscript in July indicating for the first time that CT lung volume measurements can be reliably predicted using a new calibration-based analysis method. The study showed that good volume measurement prediction results (bias, precision) could be obtained even when using low-cost reference objects, specifically three rolls of 3M Scotch Tape (TM). This novel approach, which formed the underlying computer-vision, math, and physics foundation of Accumetra’s CTLX1 and CTLX2 phantoms, is being used internationally to improve lung nodule measurements. Numerous research projects have been launched as a result of this work, investigating improved methods to predict how a CT scanner will perform when requested to measure the volume of small objects near the limits of CT resolution.
