Reducing latency in a detection system

摘要

A first multi-dimensional digital image of a scan region is generated. The scan region is included in a detection apparatus and is configured to receive and move containers through the detection apparatus. A background range of values is accessed, the background range of values representing a range of values associated with non-target materials and the background range of values being distinct from values associated with the target materials. A value of a voxel included in the multi-dimensional digital image is compared to the background range of values to determine whether the value of the voxel is within the background range of values. If the value of the voxel is within the background range of values, the voxel is identified as a voxel representing a background material. A second multi-dimensional digital image that disregards the identified voxel is generated to compress the first multi-dimensional digital image.
