Abstract

As digital slides need a lot of storage space, lack of a singular method to acquire and store these large, two-dimensional images has been a major stumbling block in the universal acceptance of this technology. The DICOMS Standard Committee Working Group 26 has put in a tremendous effort to standardize storage methods so that they are more in line with currently available PACS in most hospitals for storage of radiology images. A recent press release (Supplement 145) of these standards was hailed by one and all involved in the field of digital pathology as it will make it easier for hospitals to integrate digital pathology into their already established systems without adding too much overhead costs. Besides, it will enable different vendors developing the scanners to upgrade their products to storage systems that are common across all systems.

Keywords: DICOM; Digital pathology; z-planes.

Figure 1
Figure 1
The highest resolutions captured by an image scanner will sit at the base of the pyramid, while the apex corresponds to the zoom or low power image. When multiple z-plane (vertical level) images are present, each plane will be stored separately on one level (This figure has been modified and redrawn using Supplement 145 as reference)
Figure 2
Figure 2
The top left corner of the total imaging area is used as the point of reference and a right-handed (X, Y, Z) coordinate system is followed for position from that origin (This figure has been modified and redrawn using Supplement 145 as reference)
