TG = Thermography
XA = X-Ray Angiography RF = Radio Fluoroscopy
RTIMAGE = Radiotherapy Image RTDOSE = Radiotherapy Dose
RTSTRUCT = Radiotherapy Structure Set RTPLAN = Radiotherapy Plan
RTRECORD = RT Treatment Record HC = Hard Copy
DX = Digital Radiography MG = Mammography
IO = Intra-oral Radiography PX = Panoramic X-Ray
GM = General Microscopy SM = Slide Microscopy
XC = External-camera Photography PR = Presentation State
AU = Audio ECG = Electrocardiography
EPS = Cardiac Electrophysiology HD = Hemodynamic Waveform
SR = SR Document IVUS = Intravascular Ultrasound
OP = Ophthalmic Photography SMR = Stereometric Relationship
AR = Autorefraction KER = Keratometry
VA = Visual Acuity SRF = Subjective Refraction
OCT = Optical Coherence Tomography (non-Ophthalmic) LEN = Lensometry
OPV = Ophthalmic Visual Field OPM = Ophthalmic Mapping
OAM = Ophthalmic Axial Measurements RESP = Respiratory Waveform
KO = Key Object Selection SEG = Segmentation
REG = Registration OPT = Ophthalmic Tomography
BDUS = Bone Densitometry (ultrasound) BMD = Bone Densitometry (X-Ray)
DOC = Document FID = Fiducials
PLAN = Plan IOL = Intraocular Lens Data
IVOCT = Intravascular Optical Coherence Tomography

Retired Defined Terms for the Modality (0008,0060) are:

DS = Digital Subtraction Angiography CF = Cinefluorography
DF = Digital fluoroscopy VF = Videofluorography
AS = Angioscopy CS = Cystoscopy
EC = Echocardiography LP = Laparoscopy
FA = Fluorescein angiography CP = Culposcopy
DM = Digital microscopy FS = Fundoscopy
MA = Magnetic resonance angiography MS = Magnetic resonance spectroscopy
CD = Color flow Doppler DD = Duplex Doppler
ST = Single-photon emission computed tomography (SPECT) OPR = Ophthalmic Refraction

Note: 1. The XA modality incorporates the retired modality DS.

2. The RF modality incorporates the retired modalities CF, DF, VF.

3. The modality listed in the Modality Data Element (0008,0060) may not match the name of the IOD in which it appears. For example, a SOP instance from XA IOD may list the RF modality when an RF implementation produces an XA object.

4. The MR modality incorporates the retired modalities MA and MS.

5. The US modality incorporates the retired modalities EC, CD, and DD.

6. The NM modality incorporates the retired modality ST.

C.7.3.1.1.2 Patient Position

Patient Position (0018,5100) specifies the position of the patient relative to the imaging equipment space. This attribute is intended for annotation purposes only. It does not provide an exact mathematical relationship of the patient to the imaging equipment.

When facing the front of the imaging equipment, Head First is defined as the patient’s head being positioned toward the front of the imaging equipment. Feet First is defined as the patient’s feet being positioned toward the front of the imaging equipment. Prone is defined as the patient’s face being positioned in a downward (gravity) direction. Supine is defined as the patient’s face being in an upward direction. Decubitus Right is defined as the patient’s right side being in a downward direction. Decubitus Left is defined as the patient’s left side being in a downward direction.

The Defined Terms are:

HFP = Head First-Prone HFS = Head First-Supine
HFDR = Head First-Decubitus Right HFDL = Head First-Decubitus Left
FFDR = Feet First-Decubitus Right FFDL = Feet First-Decubitus Left
FFP = Feet First-Prone FFS = Feet First-Supine

The Figure C.7.3.1.1.2-1 illustrates these defined terms for imaging equipment with a table, such as in X-Ray Angiography. The orientation of the patient related to gravity is always recumbent.
