System and method for ultra-high frequency ultrasound treatment
View Patent ↗A non-invasive ultra-high frequency ultrasound treatment method and system are provided. An exemplary method and system comprise a high-frequency ultrasound transducer system configured for providing ultrasound treatment to a patient such that the superficial and/or subcutaneous regions of the patient can be treated. An exemplary high-frequency ultrasound transducer system comprises a control system and a transducer configured to provide treatment to the superficial and/or subcutaneous regions of interest. The high-frequency ultrasound transducer may be configured to operate at higher frequencies and controlled power levels to provide treatment to the superficial and/or subcutaneous regions of interest. For example, higher frequencies within the range from approximately 20 MHz to 500 MHz or more may be utilized.
1. A method for providing ultrasound treatment to a patient, the method comprising:
operating a transducer to emit acoustical energy within a frequency range from about 10 MHz to about 30 MHz;
coupling at least one acoustical matching layer of said transducer to an extracorporeal surface above a region of interest consisting of at least one of a superficial region and a subcutaneous region;
focusing a first acoustical energy to a first depth in said region of interest;
ablating a first portion of said region of interest;
creating a first lesion in said region of interest;
focusing a second acoustical energy to a second depth in said region of interest;
maintaining said coupling at least one acoustic matching layer during and between said focusing said first energy and said focusing said second energy;
ablating a second portion of said region of interest; and
creating a second lesion in said region of interest.
2. The method according to claim 1 , further comprising sparing tissue below said region of interest.
3. The method according to claim 1 , further comprising imaging at least a portion of said region of interest.
4. The method according to claim 3 , further comprising displaying said at least a portion of said region of interest.
5. The method according to claim 1 , further sparing intervening tissue between said extracorporeal surface and at least one of said first lesion and said second lesion.
6. The method according to claim 1 , further comprising:
focusing a third acoustical energy to a third depth in said region of interest;
ablating a third portion of said region of interest; and
creating a third lesion in said region of interest.
7. The method according to claim 6 , further comprising:
maintaining said coupling at least one acoustic matching layer during and between said focusing said first energy, and said focusing said second energy, and said focusing said third energy.
