1. An ablation device for ablating tissue within a patient, comprising: a two-dimensional array of transducer elements including a plurality of transducer elements, the two-dimensional array of transducer elements configured to deliver high intensity focused ultrasound (HIFU) energy, wherein the transducer elements have a taper and further wherein the transducer elements positioned more centrally in the two-dimensional array are larger than the transducer elements positioned more peripherally in the two-dimensional array. 2. The ablation device of claim 1, wherein the taper comprises a gradual reduction in size of the transducer elements from a center of the two-dimensional array to a periphery of the two-dimensional array. 3. The ablation device of claim 1, wherein the taper is configured such that high intensity focused ultrasound (HIFU) energy delivered from the two-dimensional array is at least approximately three decibels greater intensity at a focus zone in comparison to a grating lobe. 4. The ablation device of claim 1, wherein each of the transducer elements has an approximately equal impedance to each other ones of the transducer elements. 5. The ablation device of claim 4, further comprising an impedance match circuit operatively coupled to the transducer elements and providing, at least in part, the approximately equal impedance of each of the transducer elements to each other ones of the transducer elements. 6. The ablation device of claim 5, wherein the impedance is approximately fifty ohms at a temperature of zero degrees centigrade. 7. The ablation device of claim 4, further comprising: an acoustic membrane having an acoustic impedance and positioned with respect to the two-dimensional array; anda fluid contained within the ablation device, at least in part, by the acoustic membrane, the fluid having a fluid impedance;wherein the acoustic impedance of the acoustic membrane is approximately equal to the acoustic impedance of the fluid. 8. The ablation device of claim 7, wherein the acoustic membrane is comprised of a material having a thickness, the thickness of the acoustic membrane being a function of a difference between a speed of sound through the material and a speed of sound through the fluid to reduce a refraction of said high intensity focused ultrasound (HIFU) energy through the material. 9. The ablation device of claim 1: wherein the two-dimensional array further comprises a number of grid elements and wherein the two-dimensional array has a number of the transducer elements;wherein the transducer elements of the two-dimensional array are spatially sparse due to the number of grid elements being greater than the number of transducer elements. 10. The ablation device of claim 1, wherein the two-dimensional array of transducer elements is a two-dimensional phased array of transducer elements. 11. A method for ablating tissue of a patient, comprising: delivering high intensity focused ultrasound (HIFU) energy from a two-dimensional array of transducer elements to tissue of the patient, wherein the two-dimensional array of transducer elements includes a plurality of transducer elements, the two-dimensional array of transducer elements having a taper and further wherein the transducer elements positioned more centrally in the two-dimensional array are larger than the transducer elements positioned more peripherally in the two-dimensional array. 12. The method of claim 11, wherein the high intensity focused ultrasound (HIFU) energy delivered from the two-dimensional array of transducer elements is at least approximately three decibels greater intensity at a focus zone in comparison with a grating lobe. 13. The method of claim 11, wherein each transducer element of the two-dimensional array of transducer elements is independently actuatable, and wherein the focusing step comprises independently actuating each transducer element. 14. The method of claim 11, wherein the delivering high intensity focused ultrasound (HIFU) energy to tissue of the patient includes focusing the high intensity focused ultrasound (HIFU) energy to a focus zone at a predetermined distance from the array of transducer elements. 15. The method of claim 11, wherein each of the transducer elements has an approximately equal impedance to each other ones of the transducer elements. 16. The method of claim 11, wherein each transducer element of the two-dimensional array of transducer elements is selectively actuatable to allow for electronic steering of the high intensity focused ultrasound (HIFU) energy. 17. The method of claim 11, wherein the taper comprises a gradual reduction in size of the transducer elements from a center of the two-dimensional array to a periphery of the two-dimensional array. 18. The method of claim 11, wherein the two-dimensional array of transducer elements is a two-dimensional phased array of transducer elements. 19. The method of claim 11: wherein the two-dimensional array further comprises a number of grid elements and wherein the two-dimensional array has a number of the transducer elements;wherein the transducer elements of the two-dimensional array are spatially sparse due to the number of grid elements being greater than the number of transducer elements.
