The expression of the major porcine xenoantigens (Galalpha1-3Gal) in different tissues varies between species. The selection of suitable donors and the interpretation of studies which attempt to prevent hyperacute rejection are dependent on donor exp

Output Measurements for Medical Ultrasound ISBN: 9781447118855
This chapter deals with the use of a hydrophone to measure and characterise a single acoustic pulse or a sequence of identical acoustic pulses generated by an ultrasonic transducer. Later chapters deal with the extension of these basic techniques to

Output Measurements for Medical Ultrasound ISBN: 9781447118855
This chapter deals with the determination of the acoustic output of an ultrasonic scanner — in other words a system which is generating a non-static beam of ultrasound. Such systems could be mechanical sector, linear- or phased-array scanners. It i
