HIFU (High Intensity Focus Ultrasound)

You are here :: Home » Treatments » HIFU (High Intensity Focus Ultrasound)
High-intensity focused ultrasound (HIFU) device is one of the Development and Reform Commission.

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 Range

It is effective for the tumors which can be observed clearly by b- mode ultrasound, such as for those occurring in the abdominal cavity. This application is effective for cancers such as hepatocarcinoma, pancreatic carcinoma, prostatic carcinoma, suprarenal carcinoma, rectal cancer, carcinoma of uterus, oophoroma, breast cancer, metastatic carcinoma in the visceral cavity or in the pelvis, hysteromyoma and hyperplasia of prostate .It is also useful for dermatoma or osteolytic sarcoma.

Treatment Characteristics and Curative effect


  1. 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.
  2. Through the adoption of low intensity ultrasound there is no need for the use of anaesthesia thus risk for the patient is reduced.
  3. 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.
  4. The course of treatment is non-invasive involving no perforations, no bleeding, no pain, no heat injury and no burning experienced by the patients.
  5. 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.
  6. This method can precisely locate the tumor site and does not affect the surrounding tissue during treatment. It does not destroy the immune system.
High-intensity focused ultrasound (HIFU) is one of the most advanced medical device instruments in onco-therapy. It is the only medical instrument that has independent intellectual property rights in China and has been identified as a significant and pioneering development in the treatment of cancer. It has attracted the attention of leading cancer specialists from throughout the medical world.

Treatment principle

Tumors are directly visualized in real time by B-mode Ultrasound while the computer of the HIFU treatment device fixes and accurately orients the area to be treated with great precision. Under guided supervision the device directs focused high powered ultrasonic wave into the cancer. This focused energy acts on the cancer by raising the temperature in the targeted area to 70~100?C for predetermined periods of time leading to cancer cell death within 0.1-0.25 second. High-Intensity Focused Ultrasound (HIFU)

Treatment Applications:

HIFU is effective for tumors which can be observed clearly by B-mode Ultrasound, such as hepatocarcinoma, pancreatic carcinoma, prostatic carcinoma, suprarenal carcinoma, rectal cancer, carcinoma of uterus, ovarian carcinoma, breast cancer, metastatic carcinoma in the visceral cavity or pelvis, fibroid tumors of the uterus and hyperplasia of prostate .It is also useful for osteolytic sarcoma.

  • The computer control system accurately localizes and focuses the high powered ultrasound beam of energy which results in the, focused area temperature rising to 70 degrees Centigrade- 100 degrees Centigrade. Using a progressive sequence of high powered focused ultrasound relatively large tumors can be successfully treated.
  • HIFU successfully avoids the risk of anesthesia by focusing the low intensity ultrasound.
  • Widely used for internal organs carcinoma or metastatic carcinoma in the visceral cavity or pelvis. The course of treatment is non-invasive, without pain, perforation, bleeding and heat injury.
  • Can precisely locate and treat the tumor site and doesn't affect surrounding tissue. Unlike chemotherapy and radiotherapy, it doesn’t destroy the immune system and is without toxicity and side effect.

Warning

Next Generation PDT has been developed through many years of R & D and is demonstrating remarkable benefits for patients. Unfortunately, there are a few companies who are falsely using our trademarked name, proven success and growing reputation in PDT treatment in an attempt to lure the unsuspecting and gullible.

These Clinics and individuals are infringing our Trade Mark and are in violation of our Patent, Trademark and Copy Rights.

These three entities (one in the UK and two in China) are using outdated technologies that are clearly inferior to the advanced NG PDT technologies developed by the Next Generation PDT Group.

(They use an agent discovered by the NGPDT group over 20 years ago which has a limited in depth penetration and do not have innovative and patented light delivery system lasers and light delivery systems in addition to other deficiencies.)
