##### A.34.17.4.6 Waveform Data

For channels encoding the patient's position as fixed values Waveform Data (5400,1010) shall only contain defined values listed in Table A.34.17-2.

Table A.34.17-2. Defined Body Position Data Values

Value | Meaning
--- | ---
0x00 | supine
0x01 | left lateral decubitus
0x02 | prone
0x03 | right lateral decubitus
0x04 | upright
0xff | undefined

### Note

With 8-bit Waveform Data and a single channel there may be an odd number of samples; see PS3.5 for encoding rules.

For channels encoding the patient's rotation and elevation, angles are stored in Waveform data (5400,1010). Units of measure (Channel Sensitivity Units (003A,0211) ) shall be degrees. Both angles having the value 0Â° is body position supine. Table A.34.17-3 shows the angle values of selected body positions.

Table A.34.17-3. Selected Body Position Angles

Position Value | Value in Channel I | Value in Channel 2
--- | --- | ---
supine | 0 | 0
lateral decubitus left | 90 | 0
prone | 180 | 0
lateral decubitus right | 270 | 0
upright | 0 | 90
feet up | 0 | -90
