Features of the HIFU system
The HIFU system is the first international extracorporeal device for the ablation of solid organ
malignancy. It integrates advanced concepts and innovative practice with medical and engineering expertise into one impressive design. The system is the culmination of laboratory research, animal studies and clinical experience, and currently leads the field in the move from minimally-invasive to the non-invasive treatment of tumors. The flexible of the science on which the system is based allows the treatment of many different of tumors, both malignant and benign.
3-D conformal technique
Ensure complete targeting and ablation of solid tumor deposits.
Allows ablation of large-volume tumors in a single treatment session.
Enables ablation of malignant tumors with a surrounding margin of normal tissue, thus ensuring adequate clearance.
Real-time diagnostic ultrasound
Provides high-quality images for the location and targeting of the selected tumor.
Allows visualization of treatment as it happens, providing an assessment of therapeutic efficacy.
Real-time feedback ensures that the physician is able to tailor treatment to the specific case.
Intelligent therapeutic software
Novel software allows integration of diagnostic images and treatment parameters.
User-friendly program provides a treatment plan which can be delivered from a single console.
Provides the user with a clear representation of the acoustic focus during treatment.
Multi-dimensional motion of the therapy transducer
Enables a great variety of anatomical sites to be treated.
Electronic control allows millimetric accuracy in position.
High-intensity transducer
Well defined and reproducible focus using an acoustic lens.
Precise volume of coagulation necrosis associated with the acoustic focus.
Excellent tissue penetration allows sparing of the pre-local region.
Choice of lens provides flexibility in the depth of tumor treated.
May be driven at different frequencies depending on tumor type and depth.
Degassed water system
Provides an acoustic coupling medium.
Precisely controls the water temperature.
Filters and degassed the water to a pre-defined level.
Allows the physician direct control during the treatment session.
Adjustable ultrasound therapeutic frequency
Ensures the treatment effectiveness for various tumors.
Increases the number of tumor types suitable for treatment.
Shortens the treatment time.
