Anesthesia was induced after onset of analgesia 30 min later, via intraperitoneal injection of a cocktail of ketamine (73 mg/kg) and medetomidine (0.18 mg/kg). The animals were kept in a custom-made warmed box at 33 °C during anesthesia induction. The depth of anesthesia was monitored by testing reflexes, and additional injections were given as needed. During imaging, this was done via an intraperitoneal infusion line (30G needle with 0.28 mm inner diameter tubing) connected to a remote-controlled syringe pump. Eye ointment was applied and the skull, neck, and upper thoracic region of the mouse were shaved to avoid potential artefacts during X-ray imaging. 2 × 0.5 ml glucose 10% was administered in two separate subcutaneous injections, and tracheotomy surgery was performed, where a metal tracheal cannula with Y-adapter (outer diameter 1.0 mm, length 13 mm, depending on size of the animal.

The field of view was reduced to 2560 × 780 pixels (16.1 mm × 4.9 mm) due to the limited height of the X-ray beam. Images were recorded with 5 ms exposure time and 5 ms overhead time.
