Claim 0:
1. A method for delivering ultrasound therapy using open-loop controls, comprising:
inserting a distal tip of a therapeutic ultrasound applicator into a patient's urethra, the distal tip including an ultrasound transducer;
acquiring ultrasound images of the patient's urethra and prostate with an ultrasound imaging probe;
aligning the distal tip of the therapeutic ultrasound applicator with the patient's prostate using the ultrasound images;
delivering therapeutic ultrasound energy to the patient's prostate, with the ultrasound transducer, according to a treatment plan, the treatment plan including a predetermined limited angular range for the therapeutic ultrasound energy, the predetermined limited angular range restricting the therapeutic ultrasound energy to only a lateral and/or an anterior direction between a left transition region of the prostate and a right transition region of the prostate to avoid delivering the therapeutic ultrasound energy in an angular direction of the patient's rectum, neurovascular bundles, and internal organs other than the patient's prostate;
registering the ultrasound images with a reference location on the therapeutic ultrasound applicator to provide registered ultrasound images;
in a computer, defining the treatment plan using the registered ultrasound images;
wherein defining the treatment plan includes setting a predetermined limited radial range for the therapeutic ultrasound energy that avoids a region immediately beyond the patient's prostate and a predetermined limited axial range for the therapeutic ultrasound energy between a base and an apex of the patient's prostate;
wherein the therapeutic ultrasound is delivered without temperature feedback data.
