The RT Patient Setup Module contains information describing the positioning of the patient with respect to the treatment machine, along with any fixation devices used. It also describes the shielding devices applied to the patient. The Module contains a Sequence of patient setup descriptions, each of which may be referenced by one of more beams or brachy application setups.
Table C.8-48. RT Patient Setup Module Attributes
Identification number of the Patient Setup. The value of Patient Setup Number (300A,0182) shall be unique within the RT Plan in which it is created. |
|||
Patient position descriptor relative to the equipment. Required if Patient Additional Position (300A,0184) is not present. See Section C.8.8.12.1.2 for Defined Terms and further explanation. |
|||
User-defined additional description of patient position. Required if Patient Position (0018,5100) is not present. |
|||
Procedures and devices required to prepare a patient for treatment. Only a single Item is permitted in this Sequence. See Section C.8.8.12.1.3. |
|||
>>Include Table C.36.2.3.4-1 “RT Patient Treatment Preparation Macro Attributes”. |
|||
Sequence of setup verification images for this patient setup. |
|||
>>Include Table 10-3 “Image SOP Instance Reference Macro Attributes” |
|||
The Fixation Device Pitch Angle, i.e., orientation of PITCHED FIXATION DEVICE coordinate system with respect to IEC PATIENT SUPPORT coordinate system (degrees). Pitching is the rotation around IEC PATIENT SUPPORT X-axis. |
|||
The Fixation Device Roll Angle, i.e., orientation of ROLLED FIXATION DEVICE coordinate system with respect to IEC PITCHED FIXATION DEVICE coordinate system (degrees). Rolling is the rotation around IEC PATIENT SUPPORT Y-axis. |
|||
An identifier for the accessory intended to be read by a device such as a bar-code reader. |
|||
An identifier for the accessory intended to be read by a device such as a bar-code reader. |
|||
Sequence of devices used for patient alignment in Patient Setup. |
|||
User-defined label for Setup Device used for patient alignment. |
|||
User-defined description for Setup Device used for patient alignment. |
|||
Setup Parameter for Setup Device in appropriate [IEC 61217] coordinate system. |
|||
User-defined description of Setup Reference used for patient alignment. |
|||
An identifier for the accessory intended to be read by a device such as a bar-code reader. |
|||
Vertical Displacement in IEC TABLE TOP coordinate system (in mm) relative to initial Setup Position, i.e., vertical offset between patient positioning performed using setup and treatment position. |
|||
Longitudinal Displacement in IEC TABLE TOP coordinate system (in mm) relative to initial Setup Position, i.e., longitudinal offset between patient positioning performed using setup and treatment position. |
|||
Lateral Displacement in IEC TABLE TOP coordinate system (in mm) relative to initial Setup Position, i.e., lateral offset between patient positioning performed using setup and treatment position. |
|||
Signal source from which respiratory motion is derived. Defined Terms:
|
|||
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.
Defined Terms for Patient Position shall be those specified in Section C.7.3.1.1.2, plus the following:
The Fixation Device Sequence (300A,0190), Shielding Device Sequence (300A,01A0), Setup Technique (300A,01B0), Setup Device Sequence (300A,01B4), and Motion Synchronization Sequence (300A,0410) allow encoding of specific devices and procedures for treatment preparation.
The Patient Treatment Preparation Procedure Sequence (300A,0790) within the Patient Treatment Preparation Sequence (300A,079F) allows generic encoding of the procedures and devices.
Information in the Fixation Device Sequence (300A,0190), Shielding Device Sequence (300A,01A0), Setup Technique (300A,01B0), Setup Device Sequence (300A,01B4), and Motion Synchronization Sequence (300A,0410), if present, need to be consistent with the information in the Patient Treatment Preparation Procedure Sequence (300A,0790), if present.
