HHHH Protocol Approval Examples and​ Concepts (Informative)​

The following example is provided to illustrate the usage of the Protocol Approval IOD.​

This example shows approval of a pair of CT Protocols for routine adult head studies. It is approved by the Chief of Radiology and​ by the Physicist. The Instance UIDs of the two CT Protocols are 1.2.3.456.7.7 and 1.2.3.456.7.8.​

Note that the Institution Code Sequence (0008,0082) inside the Asserter Identification Sequence (0044,0103) communicates that​ Mercy Hospital is the organization to which Dr. Welby is responsible. The Institution Code Sequence (0008,0082) at the end of the​ first Approval Item communicates that Mercy Hospital is the institution for which the protocols are "Approved for use at the institution".​

IIII Encapsulated STL (Informative)​

The goal of encapsulating a Stereolithography (STL) 3D manufacturing model file inside a DICOM instance rather than transforming​ the data into a different representation is to facilitate preservation of the STL file in the exact form that it is used with extant manufac-​ turing devices, while at the same time unambiguously associating it with the patient for whose care the model was created and the​ images from which the model was derived.​

IIII.1 Example of CT Derived Encapsulated STL​

In this example, the patient requires a replacement implant for a large piece of skull on the left side of his head. A 3D manufacturing​ model (encoded in binary STL) was created by mirroring the corresponding section of the patient's right skull hemisphere, and then​ modified by trimming to fit the specific implantation area.​

The model was derived from a series of CT images (CT-01). The STL data in this example is the first version, having no predecessor.​ The STL data was created on November 22, 2017 at 7:10:14 AM and then stored in a DICOM instance at 7:15:23 AM. The CT images​ were acquired weeks earlier.​

The STL data was created in the coordinate system of CT-01; so they share the same Frame of Reference UID value.​

A preview image (optional) showing the rendered 3D object was created and included with the encapsulated STL as an icon image.​

No burned in annotation identifying the patient was included. The region of the skull reconstructed in the model contains no distin-​ guishing facial features of the patient.​
