Abstract: The present invention includes tools, tool kits and methods useful for treating an SI joint. In one embodiment, the present invention is a method including the steps of: implanting a graft into a SI joint of a patient, wherein the implanting comprises: creating an incision in the patient's skin proximal to the patient's SI joint; dilating the incision; creating a void in the SI joint, wherein the creating comprises displacing a portion of the patient's ilium and a portion of the patient's sacrum; and inserting a graft into the void in the SI joint, wherein the graft contacts the patient's iluim and the patient's sacrum and wherein the graft is configured to substantially fuse the patient's ilium to the patient's sacrum, thereby substantially immobilizing the patient's SI joint; inserting and immobilizing screw perpendicular to and through the inserts within the void created in the sacroiliac joint.

Abstract: Receive circuits and associated methods are provided for ultrasound imaging. Both subarray mixing and time division multiplexing are provided with a same circuit. Components of the receive circuit respond to either phasing or time slot information to implement subarray mixing or time division multiplexing. A network of switches allows combination of signals from different elements to form different sub-apertures. A controller minimizes power consumption while outputting the desired phase or time division multiplexed information by gating a clock to various registers. Each of the registers corresponds to different groups of transducer elements. For loading new phasing information, the clock is turned on to the desired register. Duration operation of the receive circuit, the clock is gated off. The register outputs the previously loaded values in a static state without clocking.
