    <subfield code="a">&lt;pre&gt;This SQLite-based database contains 2,510 respiratory signals from 419 patients (total acquisition time &amp;gt; 90 hours) with thoracic lesions treated between February 2013 and May 2022 at the Clinic of Radiotherapy and Radiation Oncology of the University Medical Center Hamburg-Eppendorf.

We believe this comprehensive dataset is of high value to the radiotherapy community as well as to researchers working on time-series analysis tasks such as forecasting and classification.
Open access to these retrospectively collected and anonymized respiratory signals was approved by the local ethics board, with the need for written informed consent waived [2023-300334-WF].&lt;/pre&gt;

&lt;pre&gt;&lt;strong&gt;Usage&lt;/strong&gt;
Please refer to the corresponding &lt;a href="https://github.com/IPMI-ICNS-UKE/respiratory-signal-database"&gt;GitHub repository&lt;/a&gt; for data reading and preprocessing functionalities.  
Additionally, review the provided README to understand the database structure.
We recommend using &lt;a href="https://sqlitebrowser.org/"&gt;DB Browser for SQLite&lt;/a&gt; as a convenient tool for browsing the database.

&lt;strong&gt;Data&lt;/strong&gt;
All respiratory signals were recorded in the course of radiotherapy treatment. 
Signals were acquired using the &lt;em&gt;Varian RPM System&lt;/em&gt; during:  
- 4D CT imaging (sampling rate: 25 Hz)  
- 4D CBCT imaging (66 Hz)  
- Dose delivery (66 Hz)  

The &lt;em&gt;Varian RPM System&lt;/em&gt; monitors an external marker block placed on the patient&amp;rsquo;s chest wall with an infrared camera.
From the obtained marker block signal, only the one-dimensional signal component representing the vertical displacement (anterior-posterior) of the chest wall is considered, resulting in univariate time series.
All patients breathed freely during acquisition without visual guidance or coaching.
Please also refer to the provided acquisition and example images for additional context.
&lt;/pre&gt;
