Paper Abstract
Our previous study presented a lossless digital signature embedding (LDSE) method for assuring the integrity of 2D
medical images in network transit or during archival. With the advent of multi-detector CT scanners and volume
acquisition technologies, a PACS exam can now potentially generate hundreds, even thousands, of images. To perform
the 2D LDSE method on each individual image in the volume would be extremely time consuming and inefficient. For
this reason, a novel 3D LDSE method has been investigated for 3D image volumes. The method begins with generating
a single digital signature (DS) of the entire volume. Embedding of the DS is performed by first identifying a bit stream
from the image volume based on the correlation of 3D pixel values. The bit stream is compressed using lossless
compression methods and the DS is concatenated with the compressed bit stream. This concatenated bit stream is then
embedded within the original image volume. During the verification process, the embedded bit stream is extracted and
utilized to recover the original bit stream and the original DS. The original bit stream can be used to restore the image
volume which in turn can be used in the verification of the DS. In addition, to 3D LDSE embedding methodology for
image volumes, a new procedure is developed to address clinical workflow for 3D image volumes. Experimental results
demonstrated that the 3D LDSE method can assure the integrity of 3D image volume efficiently and effectively. In
addition, a 3D clinical image workflow procedure was demonstrated.
