This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers are developing and testing an automated ultrasound system called uSINE that helps doctors identify the correct landmarks in your lower spine before placing spinal anesthesia or pain relief injections. The system uses ultrasound imaging and artificial intelligence to guide the needle placement more accurately. This trial will test the system in both patients with normal body weight and patients with obesity to make sure it works well for everyone.
Finding the correct spot in the spine for anesthesia can be difficult, especially in patients with obesity where standard landmarks are harder to see. This trial aims to develop technology that makes the procedure faster, more accurate, and easier for doctors to perform on the first attempt.

You will sit with your lower back exposed while researchers apply ultrasound gel and scan your spine using an ultrasound probe. The automated system will identify key landmarks in your spine and display them on a screen. In the first phase, doctors will then use this guidance to place your spinal anesthesia as normal. In later phases, additional imaging scans may be done, but no needle insertion will occur during the scanning part of the research.
