Abstract: An apparatus provides in-situ radiation treating utilizing a miniature energy transducer to produce x-rays, wherein the energy transducer includes a Schottky cathode tip. More specifically, the energy transducer includes a transducer body, an anode provided at a first end of the transducer body, and a cathode provided at a second end of the transducer body opposite the anode. The energy transducer is coupled to an energy source by a flexible insertion device. The energy source provides electrical and/or light signals to the energy transducer via the flexible insertion device. Light transmitted from the energy source to the energy transducer by the flexible insertion device is focused on a Schottky cathode tip of the cathode by the optical fiber provided in the hollow core of the anode.

Abstract: A method and system for ultrasonic imaging of bone tissue. A wide band scanning crystal transmits an ultrasonic signal of high frequency and multiple full waves into the bone tissue, and a second wide band scanning crystal receives the transmitted signal. The transmission frequency is progressively decreased until the number of full waves in the received signal equals that of the transmitted signal. At that frequency, the upper frequency limit, the number of full waves in the transmitted signal is gradually increased until the received signal contains at least two consecutive full waves of equal amplitude. The resultant transmission signal is then used to measure signal attenuation and velocity in bone tissue, in terms of standard bone imaging techniques. A lower frequency limit, below which the received signal undergoes distortion, is defined, and ultrasonic velocity depicted as a function of transmission frequency.

Abstract: A method and system for aiming a small caliber weapon at a target wherein a light beam is directed from the weapon towards an area of the target so as to form a light spot on an object in the target area and the light spot is imaged on a two-dimensional detector so as to form an image thereon whose displacement from an origin of the detector bears a predetermined relationship to a corresponding displacement of the object from a center of the target. The image of the light spot is projected on to a visor worn by a marksman having a reference mark thereon for visually determining the center of the target, and the cycle is repeated as required until the projected image of the light spot on the visor is coincident with the reference mark.
