Hello, Can someone please let me know where I could get some sample DICOM images/files for the following SOP classes: Breast Tomosynthesis Image Storage SOP Class. DICOM files: Data From Insight Journal Sample DataSet/InsightJournal.

I'd like know a free database for free download of medical images in DICOM file format.

Do you know any database?

The NIH (National Institute of Health) has a bunch of free DICOM databases (from actual real patients).

Go check the collection descriptions for more information and for instruction on how to fetch the data.

http://www.dclunie.com/ scroll to 'images'
http://www.pcir.org/index.html click 'for researcher' and then 'downloads'. Has also links to other repositories

Somewhere on the DICOM site there are several example images including multiframe images.Also Google turns up quite some sites using 'dicom example dataset'. Also the 'Visible Human Project' is available in DICOM format (again, use Wikipedia and Google).

Besides of this: A 'database' with DICOM images has the same value and implications as a database of bank accounts. I'm sure you won't find them on the net for free download.

This chapter describes the Oracle Multimedia DICOM Image Archive Demonstration, a DICOM sample application for Oracle Application Express, which you can use to build your own custom DICOM applications.

This chapter includes these sections:

See Appendix E for the location of this sample application.

Note:

This DICOM sample application is undergoing continuous improvements. Thus, the information in this chapter might not match the sample application shipped on OTN.

See the online readme.txt file that is included in the ZIP file with the Oracle Multimedia DICOM Image Archive Demonstration for information about the latest version of this sample application, and for complete requirements and instructions for installing, deinstalling, and using it.

7.1 Overview of the DICOM Sample Application

The DICOM sample application demonstrates many of the features of Oracle Multimedia DICOM. These features are as follows:

Storing and retrieving medical imaging data in the database to synchronize the DICOM data with the associated business data
Full object interfaces to Oracle Multimedia DICOM features
Extracting DICOM metadata according to user-specifiable XML schemas
Querying using extracted metadata, including querying using text that has a semantic relationship with text in the extracted metadata
Image processing, such as generating thumbnail images
Creating new DICOM objects
Validating conformance based on a set of user-specified conformance rules
Making DICOM objects anonymous based on user-defined rules that specify the set of attributes to be made anonymous and how to make those attributes anonymous
The ability to update run-time behaviors, such as constraint rules and anonymity behavior, without installing a new release of Oracle Database

The DICOM sample application is demonstrated in a browser. Because a DICOM viewer is not available, full-size JPEG images and JPEG thumbnail images are created using Oracle Multimedia DICOM features. These images are stored in a main archive table, along with the original DICOM images. Additionally, all the metadata from the DICOM images is extracted from the DICOM images to enable searching based on DICOM metadata.

Creating the Main Archive Table

Upon installation of the sample application, the main archive table dicom_archive is created with the following columns:

id - an integer used as the primary key
parent_id - an integer that identifies the original image from which the DICOM image is created (used when new DICOM content is created; for example: when making an anonymous copy of a DICOM image)
dcm_filename - the file name of the DICOM image that was imported
description - a text description of the DICOM image
dicom - the DICOM image stored as an ORDDicom object type
image - the DICOM image in JPEG format
thumb - a JPEG thumbnail image of the original DICOM image
metadata - the user-defined metadata stored as a data type XMLType
isanonymous - a flag that indicates whether the DICOM image and its associated metadata were made anonymous; if so, researchers have the ability to access the DICOM image and its metadata

The code segment shown in Example 7-1 creates the table dicom_archive.

Example 7-1 Script to Create the Main Archive Table

Note:

The preceding code segment uses SecureFiles LOB storage for the media content.

After the main archive table is created, DICOM data can be loaded. When data is loaded, all the metadata from the DICOM images is extracted to enable searching. In addition, JPEG full-size images and thumbnail images are generated for display in a Web browser.

7.2 Description of the DICOM Sample Application

The DICOM sample application includes these user interfaces:

DICOM Image Archive
DICOM Image Archive Administration

Each user interface in the sample application has a separate login page. When logging in to the DICOM Image Archive interface, clinicians and researchers must identify their roles. Administrators are automatically identified when they log in to the DICOM Image Archive Administration interface.

The DICOM Image Archive interface demonstrates the kinds of user tasks that clinicians and researchers can perform to complete one or more operations on the sample DICOM content.

Table 7-1 lists the all the tasks that are demonstrated in the DICOM Image Archive interface of the DICOM sample application, and indicates which type of user can perform each task.
