YY/T 0723-2009 is the English-translated version of 医用电气设备 医学数字影像和通讯（DICOM）-放射治疗对象.
YY/T 0723-2009 is the Chinese standard "Medical electrical equipment—Digital imaging and communications in medicine(DICOM)—Radiotherapy objects". Its scope clause reads: The report provides information on the following objects.
Radiotherapy DICOM image information of the object. This object specifies the semantic content of the RT image, usually abbreviated as RT Image IOD. It also includes the appropriate storage service class, so the IOD can be used for network storage and media exchange.
RT Image IOD range is defined by Radiation therapy image acquired cone beam imaging, such as traditional analog machines and portal imaging device. It can also be applied to the same geometry calculations Figure Like, such as digital X-ray reconstruction (DRRs).
1) DICOM radiation dose information object. This object specifies the semantic content of RT dose, usually abbreviated as RT dose IOD. It also includes the appropriate storage service class, so the IOD can be used for network storage and media exchange.
RT dose IOD The range is radiotherapy treatment planning system to calculate the dose distribution, the performance of two or three dimensional dose grid, rename or Unnamed point dose group, isodose and dose volume histograms (DVHs).
2) DICOM radiotherapy structure information object set. This object specifies the semantic content of the RT structure sets, usually abbreviated as RT knot Configuration set IOD.
It also includes the appropriate storage service class, so the IOD can be used for network storage and media exchange. RT Structure IOD range set refers to the radiation therapy equipment such as CT scanners, virtual simulation workstation or treatment planning system defined Related structures set patient.
3) DICOM radiotherapy treatment planning information object. This object specifies the semantic content RT (treatment) program, usually abbreviated as RT Plan IOD.
It also includes the appropriate storage service class, so the IOD can be used for network storage and media exchange. RT Plan IOD range refers to a predetermined external irradiation and/or geometric and dosimetric data brachytherapy procedure.
This standard includes DICOM supplement the existing part of the many; so readers understand enough to deal with DICOM standards. 1. Part 3 supplement (extension of the body, Appendix A, B, C and D).
2. Part 4 replenishment (extended to appendix B). 3. Part 6 supplement (extension of the Section 6 and Appendix A). Added to Chapter 2.

The report provides information on the following objects.
Radiotherapy DICOM image information of the object. This object specifies the semantic content of the RT image, usually abbreviated as RT Image IOD.
It also includes the appropriate storage service class, so the IOD can be used for network storage and media exchange. RT Image IOD range is defined by
Radiation therapy image acquired cone beam imaging, such as traditional analog machines and portal imaging device. It can also be applied to the same geometry calculations Figure
Like, such as digital X-ray reconstruction (DRRs).
1) DICOM radiation dose information object. This object specifies the semantic content of RT dose, usually abbreviated as RT dose
IOD. It also includes the appropriate storage service class, so the IOD can be used for network storage and media exchange. RT dose IOD The range is radiotherapy treatment planning system to calculate the dose distribution, the performance of two or three dimensional dose grid, rename or
Unnamed point dose group, isodose and dose volume histograms (DVHs).
2) DICOM radiotherapy structure information object set. This object specifies the semantic content of the RT structure sets, usually abbreviated as RT knot
Configuration set IOD. It also includes the appropriate storage service class, so the IOD can be used for network storage and media exchange. RT Structure
IOD range set refers to the radiation therapy equipment such as CT scanners, virtual simulation workstation or treatment planning system defined
Related structures set patient.
3) DICOM radiotherapy treatment planning information object. This object specifies the semantic content RT (treatment) program, usually abbreviated as RT Plan IOD. It also includes the appropriate storage service class, so the IOD can be used for network storage and media exchange. RT Plan
IOD range refers to a predetermined external irradiation and/or geometric and dosimetric data brachytherapy procedure.
This standard includes DICOM supplement the existing part of the many; so readers understand enough to deal with DICOM standards.
