摘要： An optical detection tool employs a surgical end-effector (30) and an optical fiber (20). In operation, the surgical end-effector (30) is navigated within an anatomical region relative to an object foreign to the anatomical region and the optical fiber (20) generates an encoded optical signal indicative of a strain measurement profile of the optical fiber (20) as the surgical end-effector (30) is navigated within the anatomical region. The optical fiber (20) has a detection segment in a defined spatial relationship with the surgical end-effector (30). The strain measurement profile represents a normal profile in the absence of any measurable contact of the foreign object with the detection segment of the optical fiber (20). Conversely, the strain measurement profile represents an abnormal profile in response to a measurable contact of the foreign object with the detection segment of the optical fiber (20).

摘要： Acquired echo data is corrected to reduce content from ultrasound that has undergone at least one reflection off the probe surface, for example, to reduce corresponding reverberation artefacts from imaging. In some embodiments, the propagation medium, i.e., layer or adjoining layers, through which the reverberation occurs, is, after a set of echo radiofrequency data (404, 408) has been acquired, modified in preparation for a next application of ultrasound. During that next application, it is the reverberating ultrasound signals (424), according to embodiments of the invention, that are more affected by the modification than are the non-reverberating, i.e., direct signals (420). This difference in effect is due, for example, to greater overall time of flight through the modified medium on account of reverberation in the propagation path.
