Compensated microwave thermometer for biomedical measurements
23rd European Microwave Conference, 1993, 1993A balanced radiometer for medical applications is described. The accuracy of temperature measurements doesn't depend on the reflection coefficient. Compensation of the reflection coefficient can be achieved considering losses in the transmission lines and switch. Experimental results are also presented.

Efficient 41Ca measurements for biomedical applications
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2015Abstract We present the performance of 41Ca measurements using low-energy Accelerator Mass Spectrometry (AMS) at the 500 kV facility TANDY at ETH Zurich. We optimized the measurement procedure for biomedical applications where reliability and high sample throughput is required. The main challenge for AMS measurements of 41Ca is the interfering stable

Physiological measurement in biomedical research
Physiological Measurement, 2004The key to managing a process or system is accurate measurement. From an engineering viewpoint, accurate measurement and acquisition of system observers is a fundamental necessity in order to model, understand and ultimately control a system. From a clinical viewpoint, the basis of a diagnosis is derived from observations and measurements.

Dielectric volume measurements for biomedical applications
2009 13th International Symposium on Antenna Technology and Applied Electromagnetics and the Canadian Radio Science Meeting, 2009We have developed a dielectric measurement system for recovering the properties of bulk tissue samples utilizing a specialized configuration of our microwave tomographic imaging system. We exploit the fact that the sample's location, shape and size can be determined a priori based on the known fixture geometry and integrate this with a soft prior ...

Application of air-borne ultrasound to biomedical measurements
Medical & Biological Engineering & Computing, 1982Remote measurement of distance, direction, size, form and volume are common but intricate measurement problems. We have applied the ultrasound pulse echo method, well-known from diagnostic ultrasound, for remote measurement in air. Short ultrasound pulses are emitted in air by electric excitation of an ultrasound transducer. When the ultrasonic wave is
