HIFU
Treatment principle
The entire physical tumor area can be observed by the use of b
ultrasonic waves. The location is accurately positioned by the
treating equipment under the operation and control of the computer.
Ultrasound is characterized by its deep permeability(penetration?)
and high focus.
Once the tumor has been located the equipment is used to transmit
a large capacity ultra sound wave from outside of the body to focus
onto the tumor tissue. Within seconds a high temperature of 70-
100 degrees Centigrade is generated in the focused area, killing
the cancer cells within 0.1-0.25 seconds.
Treatment Characteristics and Curative effect
- The computer controlled system accurately focuses on and
locks in to the location of the cancer cells. It generates a
temperature of 70°C - 100°C and instantly kills the cancer
cells in the tumor within an area of 3x3x10 cubic mm. thus
eliminating the tumor covering a large area.
- Through the adoption of low intensity ultrasound there is no
need for the use of anaesthesia thus risk for the patient is
reduced.
- This method of treatment is very suitable and widely used in
the cases of internal organs carcinoma or metastatic
carcinoma in the abdominal and pelvis cavities.
- The course of treatment is non-invasive involving no
perforations, no bleeding, no pain, no heat injury and no
burning experienced by the patients.
- This is very unlike the use of radiotherapy or chemotherapy
as no poisonous substances are used hence there is no
toxicity and no side-effects. The immune system of the
patient is not adversely affected at all.
- This method can precisely locate the tumor site and does not
affect the surrounding tissue during treatment. It does not
destroy the immune system.
