OO Structured Display (Informative)​

OO.1 Structured Display Use Cases​

OO.1.1 Dentistry​

Intra-oralradiographytypicallyinvolvesacquisitionofmultipleimagesofvariouspartsofthedentition.Manydigitalradiographicsystems​ offer customized templates that are used for displaying the images in a study on the screen. These templates may also be referred​ to as mounts or view sets. The Structured Display Object represents a standard method of encoding and exchanging the layout and​ intendeddisplayofStructuredDisplays.Astructureddisplayobjectcreatedinthismannercouldbestoredwithastudyandexchanged​ with images to allow for complete reproduction of the original exam.​

1.​A patient visits a General Dentist where a Full Mouth Series Exam with 18 images is acquired. The dentist observes severe bone​ loss and refers the patient to a Periodontist. The 18 images from the Full Mouth Series along with a Structured Display are copied​ to a DICOM Interchange CD and sent with the patient to see the specialist. The Periodontist uses the CD to open the exam in​ his Dental Radiographic Software and consults via phone with the General Dentist. Both are able to observe the same exam​ showing the images on each user's display using the exact same layout.​

2.​A patient requests cosmetic surgery to enhance their facial appearance. The case requires consultation between an orthodontist​ in New York and an oral surgeon in California. The cephalometric series of 2D projections constructed from the volumetric CT​ data that is used for the discussion is arranged by a Structured Display for transfer between the two practitioners.​

The anatomic information was captured​ utilizing the triplet of schema. This standard code sequence is based on ISO 3950-2010, Dentistry - Designation system for teeth​ and areas of the oral cavity.​

Every IO image should have anatomic information either through the primary or modifier sequence.​

In most standard cases, images are oriented in structured layouts. These structured displays are useful to be shared between​ providers for reference purposes.​

Table OO.1.1-1 shows structured display standard templates, where Viewset ID is based on the Japanese Society for Oral and​ Maxillofacial Radiology (JSOMR) classification provided by JIRA (Japan Medical Imaging and Radiological Systems Industries​ Association, www.jira-net.or.jp). Expected or typical teeth to be imaged location, region and designation codes are based on ISO​ 3950-2010, Dentistry - Designation system for teeth and areas of the oral cavity. For all the hanging protocols listed in OO.1.1-​ 1, the value to use for Hanging Protocol Creator (0072,0008) is "JSOMR" and the value to use for Hanging Protocol Name​ (0072,0002) does not include "JSOMR" (e.g., "DL-S001A", not "JSOMR DL-S001A").​
