# SSSS Neurophysiology Waveforms

## SSSS.1 Purpose of This Annex

This Annex describes the most common types, methods and use cases associated with the capture and usage of clinical neurophysiology waveforms.

### SSSS.1.1 Electroencephalography

Electroencephalography(EEG) is a diagnostic technique recording the electrical activity of the brain. Usually the electrodes are placed on the scalp; special techniques use electrodes implanted extracranially as well, such as sphenoidal electrodes.

EEG is used to diagnose seizure disorders and epilepsy, to monitor EEG background activity in certain conditions such as encephalopathy, anesthesia and coma, and within polysomnography studies. In clinical practice, an EEG is typically recorded for 20-60 minutes. Long term monitoring (e.g., to monitor epilepsy) may last from one hours to several days. In both cases often video of the patient is recorded as well.

Within polysomnography recordings, the EEG is used to delineate wake and sleep stages and diagnosis of parasomnias and nocturnal epilepsy.

Electrical potentials are typically in the range of 1-500 µV.

### SSSS.1.2 Electromyography

Electromyography (EMG) is a diagnostic technique recording the electrical activity of skeletal muscles. The electrical potential of the muscle cells changes on activation, due to a patient's movement or triggered by external stimulation. The data are used to detect neuromuscular abnormalities or to monitor muscular activity. In polysomnography, electromyography is used to measure muscle tension and movement.

Two different techniques are used.Surface EMG assesses muscle function by recording electrical potentials from muscle using macroelectrodes at the skin surface.Intramuscular EMG uses needle electrodes inserted through the skin into the muscle, often in combination with surface electrodes as reference.

Within Polysomnography only surface EMG is used.

Measured values are typically in the range of 50 µV - 30mV.

### SSSS.1.3 Electrooculography

Electrooculography (EOG) is a diagnostic technique to record eye movement using electrodes placed on the skin surface around the eye. EOG is used in polysomnography studies to help define the sleep stage (such as in rapid eye movement sleep) and in EEG to help differentiate eye movement artifact from frontal EEG patterns.

Typically two electrodes are used to measure the eye movement. They are placed above or below the outer canthus of the eyes.

Measured values and sampling rates are approximately in the same range as EEG.

### SSSS.1.4 Body Position

Continuous monitoring of the patient's position synchronously to the recording of neurophysiology data is an essential requirement especially in polysomnography.

Besides using synchronized video, body position can be monitored with various body position monitoring devices. Different techniques are used, e.g. simple mercury switches or acceleration sensors providing six data channels with angles and acceleration relatively to gravity.

Two types of data collection are common in polysomnography.

The first uses a single channel and records five discrete, defined values indicating the patient position: prone, lateral decubitus left, supine, lateral decubitus right, and upright.

The second used two channels to record two angles. The first channel records the patient's angle of rotation around the longitudinal axis (head-feet axis). An angle of zero indicates supine, and angle of 90° indicates left lateral decubitus, and angle of 180° indicates prone, and an angle of 270° indicates right lateral decubitus. The second channel records the angle of elevation of the patient against horizontal, which could change if the patient sits up in bed, if the head of the bed is elevated, or if the patient stands up. An angle of zero indicates the patient is lying flat, an angle of 90° indicates upright, and an angle of -90° indicates complete reverse Trendelenburg position with the head down and the legs pointed straight up.

Figure SSSS.1.4-1. DICOM Model of the Real World

Position Value | Channel I | 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

The sampling rate varies but is relatively slow (60 Hz or less).

### SSSS.1.5 Polysomnography

In sleep medicine, polysomnography (PSG) , also called a "sleep study", is a test to diagnose sleep disorders.Physiological parameters are recorded during sleep in order to identify the sleep stages, measure brain functioning, monitor respiratory control, and monitor patient movement and body position.

A polysomnography study consists of several measured quantities, the most important ones are:

- brain activity (EEG)

- eye movements (EOG)

- activity of skeletal muscles (EMG)

Additionally some of the following parameters are recorded:

- electrical activity of the heart (ECG)

- changes in blood oxygen levels (pulse oximetry)

- respiratory parameters like nasal and oral airflow via pressure transducers in front of nostrils and mouth or chest and abdominal expansion during breathing (via belts)

- sound recordings to measure snoring

- body position

Data acquisition is done via a multichannel recording unit which samples sensors attached to different parts of the patient's body. Study duration is typically up to 8 hours. Channelselection varies somewhat between labs. Recommended channels for PSG are defined by the American Academy of Sleep Medicine (Reference: Berry RB, Albertario CL, Harding SM, et al.; for the American Academy of Sleep Medicine. The AASM Manual for the Scoring of Sleep and Associated Events: Rules, Terminology and Technical Specifications. Version 2.5. Darien, IL: American Academy of Sleep Medicine; 2018).

In many cases a video is taken to show the person's movements during sleep.

#### SSSS.1.5.1 Mapping of Polysomnographic Data to DICOM

Neurophysiology time series SOP Classes relevant to sleep studies are:

Sleep Electroencephalogram Waveform Storage

  The Sleep Electroencephalogram (EEG) Waveform Storage SOP Class is the specification of digitized electrical signals from the patient's encephalon collected on the skull surface, which has been acquired by an EEG modality or by an EEG acquisition function within a polysomnography modality.

Electromyogram Waveform Storage

  The Electromyography (EMG) Waveform Storage SOP Class is the specification of digitized electrical signals evoked by the patient's muscle movements collected on the skin, which has been acquired by an EMG modality or by an EMG acquisition function within a neurophysiology recording device or a polysomnography modality.

Electrooculogram Waveform Storage

  The Electrooculogram (EOG) Waveform Storage SOP Class is the specification of digitized electrical signals evoked by the patient's eye movements collected on the face, which has been acquired by an EOG modality or by an EOG acquisition function within a neurophysiology recording device or a polysomnography modality.

Non-neurophysiologic time series or video SOP Classes relevant to sleep studies, are:

General ECG Waveform Storage

  The General Electrocardiogram (ECG) Storage SOP Class is used to store digitized electrical signals from the patient cardiac conduction system collected on the body surface, which has been acquired by an ECG modality or by an ECG acquisition function within an imaging modality or a recording device.

Basic Voice Audio Waveform Storage

  The Basic Voice Audio Storage SOP Class is used to store digitized sound that has been acquired or created by an audio modality or by an audio acquisition function within an imaging modality or a recording device. A typical use is report dictation. In the context of Polysomnography this object could be used for snoring detection

Arterial Pulse Waveform Storage

  The Arterial Pulse Waveform Storage SOP Class is used to store digitized electrical signals from the patient arterial system collected through pulse oximetry or other means by a Pulse modality or by a Pulse acquisition function within an imaging modality or a recording device. In the context of polysomnography this object could be used to record the oxygen saturation in blood.

Respiratory Waveform Storage and Multi-channel Respiratory Waveform Storage

  The Respiratory Waveform Storage SOP Classes are used to store digitized electrical signals from the respiratory system, acquired by a Respiratory modality or by a Respiratory acquisition function within an imaging modality or a recording device. In the context of polysomnography this object could be used to record the patient's respiration.

Body Position Waveform Storage

  The Body Position Waveform Storage SOP Class is the specification of digitized electrical signals, which have been acquired by adevice or sensor on the patient's body. Depending on the measurement method either the acquired sensor data or values derived from it are recorded.

Video Photographic Image Storage

  Video Photographic Image Storage Storage SOP Class is used to store visible light multiframe photographic images. This SOP Class is used to store the video data acquired during Video-EEG or in polysomnography.

### SSSS.1.6 Considerations On Storing Large Data Recordings

In principle, continuous recordings are stored within a single DICOM object, i.e., as a single file, as long as the limits resulting from DICOM data restrictions are not exceeded.

The length of Waveform Data (0054,1010), in which all of the data for a single channel is encoded, is limited to 4 GB of data by the 32 Bit unsigned integer used to store the length in bytes of the data element

For example, using 24 channels within one multiplex group, a sampling frequency of 256 Hz, and 16 Bit samples would allow amaximum recording time of more than 3 days.

Enhanced neurophysiology techniques like High Density EEG using 512 channels and a sampling frequencyof 5 kHz would reach this limit in less than 15 minutes, if all channels were stored within one multiplex group.

The file system or database, in which the DICOM data is stored, may place additional constraints on the total size of the DICOM object.

When such limits are reached, the recording has to be split into several objects with appropriate offsets and times. Synchronization has to be provided across such multiple objects.

To keep the data objects easy to handle, long duration recordings could be split in time slices of e.g., single days.

In addition, it may be desirable to use smaller objects to address reliability and random access concerns.

Such objects consisting of one recording being split to multiple parts shall belong to the same series.
