The Compact Delta II uses Dornier's proven Electromagnetic Shockwave Emitter (EMSE) technology to deliver consistent and dependable power. Imaging flexibility is obtained through X-rays or optional isocentric ultrasound. The C arm rotates +/- 30 degrees, allowing for visualisation of stones from various positions, and also offers two modes for X-rays: standard fluoroscopy and boost fluoroscopy. The optional isocentric ultrasound uses a patented localisation arm that makes ultrasound targeting quick and easy. It also shortens intervention times and reduces side effects.
