Publication number: 20070018644Abstract: A method for analysing signals received from an object. The method initially comprises deriving the parameters of frequency and phase of said signals in either the time domain or frequency domain. It then comprises identifying whether the signals conform to a linear relationship between the two parameters to ascertain whether a true signal representative of a character of the object is present. The character may be a nuclear or electronic resonance, such as NQR, NMR or ESR, which is indicative of a particular substance. Signal processing methods involving HTLS, HSVD, MPM, MMPM, FFT, STFT and STMPM are also described.Type: ApplicationFiled: January 30, 2004Publication date: January 25, 2007Inventors: John Flexman, Warrick Chisholm, Peter Hayes, Vassili Mikhaltsevitch, Taras Rudakov

Publication number: 20060145697Abstract: A coil assembly (11) comprising two coil sections (13a and 13b). Each of the sections (13) consists of a combination of a spiral coil (15) having a variable coil pitch arranged in a saddle shape configuration. The saddle shape has a central portion (17) and a pair of outer coextending portions (19). The coil sections (13) are located opposite each other with the central portions (17) of the respective sections disposed in parallel spaced apart relationship and the corresponding coextending portions (19) of the respective sections disposed in coplanar alignment with each other so that the sections combine to circumscribe a scanned volume within which the target substance is to be disposed.Type: ApplicationFiled: November 6, 2003Publication date: July 6, 2006Inventors: Vassili Mikhaltsevitch, Taras Rudakov, Warrick Chisholm, John Flexman, Peter Hayes

Publication number: 20060091883Abstract: An apparatus and a method for producing a multi-pulse sequence for irradiating a substance provided with quadrupole nuclei with either integer or half-integer spins to detect an NQR signal emitted therefrom. The apparatus has pulse sequence generating means adapted to produce a combination of two or more pulse sequences, arranged so that a definite regularity of the phase alteration of pulses in each of the pulse sequences occurs that is equivalent to a shift of spectral components of the pulse sequences in relation to each other. Furthermore, in at least one of the pulse sequences, there are not less than two phases alternating. A preparatory pulse may be included in one of the pulse sequences to reduce the effect of temperature, increase the intensity of the NQR signal and simultaneously eliminate intensity anomalies. Alternatively, the combination of pulse sequences may be different from a combination of PAPS and NPAPS, and none of the pulse sequences contain a preparatory pulse.Type: ApplicationFiled: June 20, 2003Publication date: May 4, 2006Inventors: Vassili Mikhaltsevitch, Taras Rudakov, John Flexman, Peter Hayes, Warrick Chisholm

Publication number: 20060033499Abstract: A receiving system (11) for connection to an antenna arrangement (19) for detecting response signals from a substance having quadrupolar nuclei excited so as to produce nuclear quadrupole resonance in certain of the quadrupolar nuclei. A method for receiving a response signal via the antennae arrangement (19) is also described. The receiving system (11) includes an amplifier (17) to amplify the received response signal from the antenna arrangement (19) for subsequent processing, a matching section (15) to match the amplifier (17) to the antenna (19), and an isolating switch (13) to isolate the antenna from the receiving system (11). The matching section (15) noise matches the receiving system (11) to the antenna (19) during a receiving period to reduce the Q factor of the antenna without significantly degrading the signal to noise ratio.Type: ApplicationFiled: June 13, 2003Publication date: February 16, 2006Inventors: John Flexman, Peter Hayes, Warick Chisholm, Vassile Mikhaltsevitch, Taras Rudakov
