Recall details

Why it was recalled

According to the FDA_DEVICE notice, the identified hazard is: There is an anomaly with the Eclipse(TM) Treatment Planning System [TPS] Proton Convolution Superposition [PCS] dose calculation algorithm. The PCS algo- rithm calculates the water equivalent range incorrectly for non-square 3D CT images (either different number of pixels in X and Y, or non-square pixels). Before the dose is calculated, Eclipse resamples the CT images to create a calculation image with a maximum resolution of 256 x 256. The PCS algorithm assumes uniform resolution in X and Y directions, or that X = Y for all images, and erroneously sets the Y = X for dose calcu- lation. For images that are not square, where either X<>Y, or the length of X does not equal the length of Y, the computed water equivalent range R is erroneous compared to the correct range R: 1) X=Y; R =R (R is correct); 2) X<Y: R <R (R is too small) and 3) X>Y R >R (R is too big).

This Class II recall concerns device products distributed in United States and was recorded by FDA_DEVICE. Recalls in this category are published so that owners, retailers, and importers can identify affected units and act quickly.
