C.8.4.11.1 NM Detector Attribute Descriptions​

C.8.4.11.1.1 Focal Distance​

Focal Distance (0018,1182) for NM Image data is the focal distance, in mm for converging or diverging collimators, measured from​ the front face of the detector to the focus. Positive values indicate converging and negative values indicate diverging collimators. A​ value of 0 means infinite distance for parallel collimation.​

C.8.4.11.1.2 Focus Center​

X Focus Center (0018,1183) and Y Focus Center (0018,1184) for NM Image data is used to define the projection of the focus for a​ converging or diverging collimator within the un-zoomed Field of View. It is defined in mm for row and column relative to the center​ of the un-zoomed Field of View.​

C.8.4.11.1.3 Zoom Center​

Zoom Center (0028,0032) is the offset between the un-zoomed camera field of view and field of view, measured from the center of​ the un-zoomed camera field of view to the center the of the zoomed field of view. The offset is measured in mm in the un-zoomed​ camera FOV dimensions. Positive values are to the right and down from the un-zoomed center, as viewed from the image plane.​ When this Attribute is not given, the Zoom Center is assumed to be 0\0.​

C.8.4.11.1.4 Zoom Factor​

ZoomFactor(0028,0031)isthemagnificationfactorthatwasusedduringtheacquisition.WhenthisAttributeisnotgiven,itisassumed​ to be 1.0\1.0.​

Note​

Zoom Factor (0028,0031) is informational only. Pixel Spacing (0028,0030) already takes account of this and any other​ changes to pixel size.​

C.8.4.11.1.5 Center of Rotation Offset​

Center of Rotation Offset (0018,1145) is the average amount of offset in mm between the Detector Field of View center and the​ physicalcenterofrotationofthegantryforcircularorbitalscans.Positivevaluesindicatethephysicalcenteristotherightoftheimage​ plane center.​

If:​

1.​Image Type (0008,0008) Value 3 is TOMO or GATED TOMO, and​

2.​Corrected Image (0028,0051) does not include the value "COR", and​

3.​Center of Rotation Offset (0018,1145) is non-zero,​

then the receiver should assume that Center of Rotation correction has not already been done.​

- Standard -​

Page 650​

DICOM PS3.3 2020a - Information Object Definitions​

If the Center of Rotation Offset is zero, no correction shall be applied.​

C.8.4.11.1.6 Gantry/Detector Tilt​

Gantry/Detector Tilt (0018,1120) for NM Image data is the angle in degrees of the detector face relative to the patient's major (Head​ to Feet) axis (or the table supporting the patient). Positive tilt is towards the patient's feet.​
