### C.7.2 Common Study IE Modules

The following Study IE Modules are common to all Composite Image IODs that reference the Study IE. These Modules contain Attributes of the patient and study that are needed for diagnostic interpretation of the image. They contain Attributes that are also in the Patient Modules in Section C.2 and Study Modules in Section C.4.

#### C.7.2.1 General Study Module

Table C.7-3 specifies the Attributes that describe and identify the Study performed upon the Patient.

##### C.7.2.1.1 General Study Attribute Descriptions

###### C.7.2.1.1.1 Referring Physician, Physician of Record, Physician Reading Study

The model used for application of attributes related to different functions of Physicians involved in the care of a patient is shown in Figure C.7.2-1. Figure C.7.2-1 shows some of the relationships and information flows between physician roles that might be present in some healthcare business models.

Figure C.7.2-1. Functions of Physicians

There can be an overlap of functions provided by any given physician. In this case, the various attributes specifying the different roles would convey the same physician name.
