A therapeutic endocavity probe for treating tissues in particular of the prostate by emission of focused ultrasonic waves, including a support forming a guide tube extended by a mounting head for at least one therapy transducer component with an active surface emitting focused ultrasonic waves and having a spherical front of a total surface area in which a surface window is laid out for mounting an imaging transducer. According to the invention, the therapy transducer component has a front face having a total surface area equal to the sum of the active surface area equal to 1,500 mm&#xb1;200 mm, and of the surface area of the window for letting through the imaging transducer, the ratio of the surface area of the window over the active surface area of the therapy transducer component being less than or equal to 0.45.
