This module specifies the Attributes of the RT Image Module, which describe RT-specific characteristics of a projection image. The image described by these Attributes must be a radiotherapy image acquired or calculated using a conical imaging geometry.

The Enhanced RT Image IOD represents projection images generated before, during or after Radiotherapy treatment sessions. The projection images may be acquired directly or may be derived ("reconstructed") from volumetric data such as CT.

The focus for this Radiotherapy Image IOD (RT Image IOD) is to address the requirements for image transfer found in general radiotherapy applications performed on conventional simulators, virtual simulators, and portal imaging devices.

The Image Plane Pixel Spacing (3002,0011) Attribute shall always be defined on the image plane, i.e., at the radiation machine source to image plane distance specified by RT Image SID (3002,0026).

2012年8月8日 · Images with modality SC or VL serve as visible light photos for visual setup control. Images with modality RTIMAGE serve as reference images on plan level. RT Images present in this Sequence shall not be referenced in the Referenced Reference Image Sequence (300C,0042) of the RT Beams Module.

If the pixel data of the derived Image is different from the pixel data of the source images and this difference is expected to affect professional interpretation of the image, the Derived Image shall have a UID different than all the source images.

The focus for this Radiotherapy Plan IOD (RT Plan IOD) is to address the requirements for transfer of treatment plans generated by manual entry, a virtual simulation system, or a treatment planning system before or during a course of treatment.

2014年8月8日 · The X-Ray Image Receptor Angle (3002,000E) specifies the rotation of the image receptor device in the IEC X-RAY IMAGE RECEPTOR PLANE. A positive angle corresponds to a counter-clockwise rotation of the X-Ray Image Receptor as viewed from the radiation source in the IEC GANTRY coordinate system.
