◼ Cradle Type: 3.0 (Prostate)
◼ Software version: 8.1
System Specifications:
◼ Transducer: 990 transmit elements flat phase array
◼ Transducer aperture (diameter): 34x22mm
◼ Focal distance: 15-60mm (achieved by electronic steering)
◼ Frequencies: 2.3±0.25Mhz
◼ Maximal Energy per
macro-spot: 30KJ
◼ Maximal energy per sub-spot: 2.2KJ
◼ Energy specifications:

2
● Ultrasound output: ~45W
● Max output pulse width: 512sec
◼ Effective radiating area (ERA): 748mm
2
◼ Focal region size: Variable
◼ Focal control: Electronic
◼ Tissue destruction mechanism: Thermal coagulative necrosis
◼ Imaging during treatment: PRF MR Images at 3-6seconds interval
◼ Temperature measurement: Proton Resonance Frequency (PRF) MR thermometry
◼ Reflection monitoring: None
◼ Cavitation monitoring: Real time display
◼ Treatment outcome monitoring method: Using real-time thermometry the operator gets real time
feedback on treatment outcome, as temperature is correlated to tissue viability.
◼ Independent assessment using standard MR imaging sequences is done during and after treatment,
to assess lesion size and location.
◼ System Electrical Specifications:
● Rated power voltages/currents: 208V (30A) / 380-400V (15A) / 480V (13A)
