Row 2​

"Projection X-Ray" refers to procedures performed on either integrated equipment (where information is passed​

between the X-Ray source (generator and tube), detector, and mechanical systems), or non-integrated equipment​

(where data might not be available for one or more components such as cassette-based systems). The data​

availability can be described in Rows 8, 9 and 10. The specific type of equipment can be described in Row 4.​

The coded term for "Mammography" is intended to encompass all types of projection X-Ray imaging of the breast.​

Note​

Mammography exams are distinguished by a different value in this attribute, Angiography exams are​

distinguished by the Irradiation Event Type attribute = Fluoroscopy, CR/DR exams are distinguished by​

one or more of the Data Availability Flags = No, and CT exams are distinguished by the use of a different​

Template.​

Row 5​

The observer context may include both a Person Observer identification, as well as the identity of the equipment​

providing the values for the irradiation event (Device Observer identification), if not inherited.​

Row 8​

A value of "No" indicates that details associated with the X-Ray Detector are not available to the device generating​

thisreport.Forexample,anX-RaySourcesystemmightlackanycommunicationwiththeassociatedcassette-based​

X-Ray detector or any method of entering such information.​

A value of "Yes" or the absence of this row means that the details are available.​

Row 9​

A value of "No" indicates that details associated with the X-Ray Source are not available to the device generating​

this report. For example, a cassette-based X-Ray detector might lack any communication with the associated​

X-Ray Source or any method of entering such information.​

A value of "Yes" or the absence of this row means that the details are available.​

Row 10​

A value of "No" indicates that details associated with the Gantry and/or Table are not available to the device​

generating this report. For example, a cassette-based X-Ray detector might lack any communication with the​

associated gantry/table or any method of entering such information.​

A value of "Yes" or the absence of this row means that the details are available.​

Row 11​

Cassette-based X-Ray systems should consider themselves to be Single Plane systems.​

Row 14​

Details of the underlying irradiation events. If Row 18 has a value of "MPPS Content" then a TID 10003 “Irradiation​

Event X-Ray Data” item may be generated for each item in the MPPS Exposure Dose Sequence (0040,030E), but​

since this is an optional element in MPPS, if it is absent, empty or incomplete, there may be no irradiation event​

level information available. Alternatively, the information may be copied or computed from the images.​

Row 16​

The Dose Image references a graphic representation of the radiation dose distribution. This may be a Secondary​

Capture scan of a dosimetry film.​

Row 17​

The physician responsible for determining that the irradiating procedure was appropriate for the indications. The​

valuemaycomefromRequestingPhysician(0032,1032),RequestingPhysicianIdentificationSequence(0032,1031)​

or somewhere else based on hospital policies.​

Row 18​

The primary source of information from which this dose object was constructed. The Source of Dose Information​

(Row18)isindependentoftheScopeOfAccumulation(Row6);e.g.,itwouldbetypicaltohaveascopeof(113016,​

DCM, "Performed Procedure Step"), but a source of (113856, DCM, "Automated Data Collection") rather than​

(113858, DCM, "MPPS Content").​

The Equipment Landmark Y Position is not recorded since it is, by definition, in the plane of the table as is the​

origin of the Table Coordinate System so the value would always be zero.​

Row 19​

In many instances, the values will be either:​

•​EV (128772, DCM, "Reference Basis") [1354] = (88986008, SCT, "Vertex of Head") with EV (128773, DCM,​

Row 20​

This distance (likely recorded by the operator) locates the patient with respect to an X-Ray table landmark.​

The patient is assumed to be centered in the left-right axis of the X-Ray table.​
