Frame Type Attribute

Tag(0008,9007)
TypeRequired (1)
KeywordFrameType
Value Multiplicity4-5
Value RepresentationCode String (CS)

Type of Frame. A multi-valued Attribute analogous to Image Type (0008,0008).

Enumerated Values and Defined Terms are the same as those for the four or five values of Image Type (0008,0008), except that the value MIXED is not allowed unless the SOP Class UID is "1.2.840.10008.5.1.4.1.1.2.2" (Legacy Converted). See Section C.8.16.1 and Section C.8.15.2.1.1.

Note

Part of the CT Image Frame Type Functional Group Macro with usage: M

Section C.8.16.1

C.8.16.1 Image Type and Frame Type

Image Type (0008,0008) and associated Attributes provide a high level description of a multi-frame SOP Instance. Image Type (0008,0008) contains the highest level summary of what is in the SOP Instance.

Frame Type (0008,9007) mirrors the corresponding Image Type Attribute and applies to the frame level.

If more than one value is used by the set of frames for a given Frame Type (0008,9007) Attribute value or associated Attribute value then the corresponding value of Image Type (0008,0008) or associated Attribute shall contain a value of MIXED. This indicates that a mixed set of values exists within the multi-frame SOP Instance.

The value MIXED shall only be used in Image Type (0008,0008) when the corresponding values for the individual frames are not equal. When a value of an Attribute is equal for all frames, the same value shall be used for the corresponding value of Image Type (0008,0008). Values 2 and 3 of Image Type (0008,0008) are an exception to the rule for MIXED: Values 2 and 3 may never have the value of MIXED as described in Section C.8.16.1.2 and Section C.8.16.1.3.

Image Type (0008,0008) and Frame Type (0008,9007) shall consist of four values, except that a fifth value shall be present if Multi-energy CT Acquisition (0018,9361) has a value of YES.

C.8.16.1.1 Pixel Data Characteristics

Value 1 of Image Type (0008,0008) and Frame Type (0008,9007) shall use one of the following Enumerated Values from Table C.8-127.

Value 1 of Image Type (0008,0008) and Value 1 of Frame Type (0008,9007) shall not be zero length.

Table C.8-127. Image Type and Frame Type Value 1

Enumerated Value Name

Enumerated Value Description

ORIGINAL

An image or frame is original if its pixel data was directly reconstructed from the original data that is obtained from the sensors of the imaging equipment, Image Type (0008,0008) Value 4 is NONE, and Volume Based Calculation Technique (0008,9207) is NONE.

Note

  1. For MR, original data is data directly reconstructed from k-space data.

  2. For CT, original frames are those directly reconstructed from projection data.

DERIVED

An image or frame is derived if its pixel data was calculated from original or other derived pixel data (i.e., it is not original).

MIXED

Used only as a value in Image Type (0008,0008) if frames within the SOP Instance contain different values for Value 1 in their Frame Type (0008,9007).


C.8.16.1.2 Patient Examination Characteristics

Value 2 for Image Type (0008,0008) and Frame Type (0008,9007) follows the standard definition and shall have the following Enumerated Value from Table C.8-128.

Value 2 of Image Type (0008,0008) and Value 2 of Frame Type (0008,9007) shall not be zero length.

Table C.8-128. Image Type and Frame Type Value 2

Enumerated Value Name

Enumerated Value Description

PRIMARY

See Section C.7.6.1.1.2


C.8.16.1.3 Image Flavor

Value 3 is an overall representation of the image type. This value may be a summary of several other Attributes or a duplication of one of the other Attributes to indicate the most important aspect of this image. Value 3 Image Flavor is to be used with Value 4 Derived Pixel Contrast to indicate the nature of the image set.

Note

For example Value 3 = DIFFUSION together with Value 4 = NONE indicates that the image set was originally collected for DIFFUSION.

If Value 3 = DIFFUSION together with Value 4 = DIFFUSION this indicates that the object contains DIFFUSION weighted post processed images.

Value 3 of Image Type (0008,0008) shall not be zero length.

Value 3 of Frame Type (0008,9007) may have the same value as found in Value 3 of Image Type (0008,0008), or may have a different value.

The Attribute value may not be MIXED as this value needs to be a summary of the primary purpose of the images, whether the frames have the same value or not.

Table C.8-129 specifies the Defined Terms for Value 3 for Image Type (0008,0008) and Frame Type (0008,9007) that are common to CT and MR. Additional Defined Terms are defined in the modality-specific Module and Macro definitions.

C.8.16.1.4 Derived Pixel Contrast

Value 4 may have the value QUANTITY if the derived pixel contrast is described in the Quantity Definition Sequence (0040,9220) of the Real World Value Mapping Macro.

Note

If more than one of the following derived types is applicable, then it is up to the generating application to specify the value that best characterizes the derived image.

Value 4 of Image Type (0008,0008) and Value 4 of Frame Type (0008,9007) shall not be zero length unless the SOP Class UID is "1.2.840.10008.5.1.4.1.1.2.2" or "1.2.840.10008.5.1.4.1.1.4.4" or "1.2.840.10008.5.1.4.1.1.128.1" (Legacy Converted).
