The DICOM Standards
Committee exists to create and maintain international standards for communication
of biomedical diagnostic and therapeutic information in disciplines that use
digital images and associated data. The
goals of DICOM are to achieve compatibility and to improve workflow efficiency
between imaging systems and other information systems in healthcare
environments worldwide. DICOM is a
cooperative standard. Connectivity
works because vendors cooperate in testing during scheduled public
demonstration, over the Internet, and in private test sessions. Every major diagnostic medical imaging
vendor in the world has incorporated the standard into its product design, and
most are actively participating in the enhancement of the standard. Most of the professional societies
throughout the world also support and participate in the enhancement of the
standard. DICOM is used, or will soon
be used, by virtually every medical profession that utilizes images within the
healthcare industry. These include
cardiology, dentistry, endoscopy, mammography, ophthalmology, orthopedics,
pathology, pediatrics, radiation therapy, radiology, surgery, etc. DICOM is even used in veterinary medical
imaging applications.

Modern MR pulse sequences
cannot be described sufficiently by the current standard. Furthermore, new
applications such as functional MR and MR fluoroscopy, as well as the
non-imaging application MR spectroscopy, are not supported either. The organization of increasingly large datasets as single frame objects is far
from optimal, and limitations of the existing definitions of spatial and
temporal attributes are apparent. It
has therefore been proposed that a new MR object be developed that contains a
more extensive set of descriptive attributes and makes use of the multi-frame
mechanisms and/or variants thereof as originally introduced by the nuclear
medicine, ultrasound and x-ray angiography objects.

Date of Last Update: December 31, 2001
To
extend the DICOM Standard with respect to 3D and other multi-dimensional data
sets. WG17 is extending DICOM to
represent data types greater than two dimensions. In existing DICOM, the atomic unit of image data is the 2D
frame. Some emerging acquisition
modalities (as well as 3D visualization and quantitative analysis applications)
are volumetric-based. These need a
volumetric friendly representation.
Additionally, new diagnostic modalities may generate data with multiple
components. Existing DICOM does not support this.

To
extend the DICOM Standard with respect to clinical trials information and the
storage of images for educational purposes.
DICOM
Working Group 18 was first convened in 1999 to address issues unique to the use
of images in clinical trials and education.
The working group elected to focus, first, on clinical trials before
devoting significant time to education and imaging teaching files.
In its initial meetings,
the Working Group determined that there are several shortcomings of the current
DICOM standard when it is used in the context of clinical trials. First, there are no standard methods for “scrubbing”
patient-identifying information from the DICOM header while retaining
identifiers to reestablish the patient’s identity for audit purposes. Second, a variety of clinical trials
attributes are missing these include the ability to capture a unique subject
identifier, the protocol for which an image was obtained and the sponsor of the
clinical trial. Third, even when some
of this information is stored in optional fields, the storage arrangement
varies according to vendor and frequently cannot be displayed on off-the-shelf
workstations. Fourth, certain common
imaging parameters that are essential for the conduct of clinical trials, such
as MR echo time and repetition time, are not stored in consistent locations.

To develop an extended CT
image object to support the many technological and clinical advances in
Computed Tomography. In particular, the
increase in the number of slices in an exam and the real-time capabilities of
CT technology makes it desirable to create a new DICOM object with a
multi-frame capability. Consistency
with the MR Multi-Frame IOD under specification is important as many
workstations support both CT and MR applications. Consistency with the new XA Multi-frame IOD is also important so
that Cardiology or Angiography applications can benefit from both CT and X-ray
acquisitions.
