    摘要： An anatomical position sensing system (100) using one or more substantially spherical transponders for measuring relative positions and distances. Transponders (P) and (S) are capable of receiving and transmitting RF signals, and communicating between themselves and with a separate CPU (112). The CPU (112) is controlled by an operator at an operator control panel (114), interacts with an alarm (120) for providing audible alerts to the operator, and a display for displaying information to the operator. The CPU (112) controls a broadband antenna (118) to transmit, at a frequency f1, a low-frequency RF power signal (122) across a wide field to energize the transponders (P) and (S). Directional components (122a) and (122b) intercept and energize the transponders (P) and (S). Once energized, transponder (P) transmits a range signal in all directions including component (124) at a very high RF frequency f2, extending from transponder (P) to transponder (S). Upon receipt of the range signal (124), transponder (S) emits a data signal at a very high RF frequency f3 in all directions, including component (126), which is directed at the antenna (118). The distance (D) is determined by measuring the attenuation of the range signal (124) as it is received by transponder (S). Transponder (S) then modulates the value of the strength of the incoming range signal (124) onto the data signal. The CPU (112) computes the distance (D) from the incoming data signal (126) from a lookup table derived from a sequence of calibration steps prior to beginning normal operation.

    摘要： A solid state X-ray detector (106) is disclosed which is comprised of a plurality of Spherical ICs (202)-(208) disposed on a substrate (210). The Spherical ICs each have a plurality of detector picture elements (pixels) (302) disposed on the surface thereof. Each of the pixels (302) is formed from a layer of hydrogenated amorphous silicon (502) with a heavy metal layer (504) of molybdenum (Mo) disposed thereon as the cathode and a metal layer (508) disposed on the lower surface thereof. The cathode is reverse biased and X-rays impinging thereon will cause a transfer of electron-holes to the lower plate, which are stored on a capacitor (608). The electrons are accumulated over a predetermined period of time and then sampled and processed for output on a display (12) in real time or for storage of a digital value in a memory (114).

    摘要： Sensor modules are provided which are pumped into a well by first being pumped downhole within a drill string, then passing through the drill bit and being circulated uphole in the annulus between the drill string and the borehole of the well. The sensors take measurement readings as they are being pumped uphole through the annulus. The sensors are preferably separated from the mud returns from the well, and then read at an inductive read unit. The sensor modules are provided by semiconductor substrates which measure downhole well parameters, and then store the date for retrieval at the surface. The semiconductor substrates preferably have a plurality of sides on which measurement sensors and circuitry may be formed, allowing the circuitry and the sensors to be made of smaller sizes. Such sensors include temperature sensors, three-dimensional stain gauges, which are also useful as pressure transducers, inductive pressure transducers, inclination sensors, accelerometers, gyroscopes and radiation detectors. The sensors and circuitry are preferably provided on spherically shaped semiconductor substrates.

    摘要： A miniature spherical-shaped internal temperature transponder. A temperature sensor (25) is fabricated in a spherical integrated transponder circuit (15) which may be placed in the human body by ingestion, implantation, or injection. In one aspect of the invention, a passive system is disclosed whereby an external monitoring station (13) generates an energy field using a magnetic field generator (19) which is coupled to a power coil (21) of the transponder (15). The power coil (21) passes power to a power regulator (23) to provide regulated power to all transponder (15) circuits. Temperature data obtained by the temperature sensor (25) is passed to a voltage controlled oscillator (27) for conversion into an RF signal. A mixing circuit (31) receives the RF temperature signal and modulates the temperature data signal onto an oscillator frequency from an RF oscillator (29). An RF amplifier (33) receives the modulated RF signal from the mixing circuit (31) and transmits it via an antenna (35) to the external monitor station 13 which is proximate to the transponder (15). The signal is received by an RF receiver (37) and processed using a CPU (39) to extract the measured temperature data, which can then be displayed to the operator on a display (41). The transponder (15) may be powered either by the external electromagnetic radiation source (19) or an internal battery.

    摘要： A method of tumor ablation using injectable thermal-sensing balls. A catheter system (115) is used to inject a slurry (134) of thermal-sensing balls (136) into a tumor (122) located in, for example, a liver (120). The catheter system (115) comprises a catheter (128) and a specialized syringe (129) consisting of a housing (130) and a plunger (132). The housing (130) includes a cylindrical chamber having the slurry (134) of thermal-sensing balls (136). The catheter (128) is inserted retrograde into the femoral artery and passed to the site of the tumor (122). The hepatic artery (124) branches into smaller vessels, one of which is a tumor artery (126) which feeds the tumor (122). The tip of the catheter (128) is placed in the tumor artery (126) guided by conventional fluoroscopy. The injected balls (136) then receive energy from an external control system (110). The system (110) comprises a control panel (114) as an operator interface for controlling the system (110) and reading data therefrom. A CPU (112) is used for control and monitor of the operation, and transmits power and signals to the injected balls (136) via a radiating antenna (118), which energy is converted into heat to increase the temperature of the tumor (122). The temperature of the balls (136) can then be read from one or more onboard temperature sensors, and displayed to the operator for accurate control of the tumor temperature.
