CP-2215 Measurements and Categorical Statements on Patients, Studies and Series Status Final Text Date of Last Update 2022/12/01 Person Assigned David Clunie Submitter Name Imaging Data Commons (IDC) Submission Date 2022/02/11 Correction Number CP-2215 Log Summary: Measurements and Categorical Statements on Patients, Studies and Series Name of Standard PS3.6, PS3.16 2022d Rationale for Correction: Some AI/ML and other image processing applications as well as human observers make categorical and numerical statements about patients, studies and series rather than images, frames or ROIs. It is useful to be able to include these in TID 1500 reports. Update TID 1501 to allow references to patients, studies and series.

Measurement groups may contain various common measurement modifiers that are shared by all measurements in the group, such as method and finding site. Type: Extensible Order: Non-Significant Root: No

Content Item Descriptions Row 1a Specifies the type of entity that is the subject of this measurement group. If this is the entire Patient, then the current specifies that Patient; it defaults to the Attributes of the Patient Module. ... Rows 10b, 10c, 10d, 10e, 10f, 10g, 10h Coordinates, image or waveform references that are the subject of this measurement group instead of, or in addition to, coordinate, image or waveform references associated with measurements in Row 10. Note that if an ROI is defined, other templates may be used, such as TID 1410 Planar ROI Measurements and Qualitative Evaluations. Row 10i The Study that is the subject of this measurement group. Row 10j The Series that is the subject of this measurement group. Rows 11, 11b, 12 Allows encoding a flat list of name-value pairs that are coded questions with coded or text answers, for example, to record categorical observations related to the subject of the measurement group. A single level of coded modifiers may be present.

112002 Series Instance UID A unique identifier for a series of DICOM SOP instances.
110180 Study Instance UID ParticipantObjectID type: Study Instance UID.
121025 Patient A patient is the subject of observations.
113014 Study A study is a collection of one or more series of medical images, presentation states, and/or SR documents that are logically related for the purpose of diagnosing a patient. A study may include composite instances that are created by a single modality, multiple modalities or by multiple devices of the same modality. [From ]
113015 Series A distinct logical set used to group composite instances. All instances within a Series are of the same modality, in the same Frame of Reference (if any), and created by the same equipment. [See ]
121024 Subject Class Type of observation subject.
130780 Specific observation subject class The type of entity that is the subject of a specific observation, such as a measurement or qualitative evaluation. E.g., a region of interest, image, series of images, study or patient. This is distinct from the Subject Class used in Observation Context, which more generally specifies the entire subject, usually the patient.
130781 Image frame A single two-dimensional pixel plane of an image. Usually used in the context of a multi-frame image.
PS3.16 for reference unchanged:
Subject Context This Template contains identifying (and optionally descriptive) attributes of the subject of the observation. Subject context identifies (and optionally) describes the subject of the observation, whether it be a patient (human or animal), a fetus (human or animal), a specimen, or a device.
