Publication number: 20090182237Abstract: An acoustic probe transmits/receives acoustic pulses with frequencies both in a high frequency (HF), and a selectable amount of lower frequency (LF1, LF2, . . . , LFn, . . . ) bands. The radiation surfaces of at least two of the multiple frequency bands have a common region. The arrays and elements can be of a general type such as annular arrays, phased or switched arrays, linear arrays with division in both azimuth and elevation direction, like a 1.5D, a 1.75D and a full 2D array, or curved arrays. The element division, array type, and array aperture sizes for the different bands can also be different.Type: ApplicationFiled: January 9, 2009Publication date: July 16, 2009Inventors: Bjorn A.J. Angelsen, Tonni F. Johansen, Rune Hansen, Sven Peter Nasholm, Svein-Erik Masoy

Publication number: 20090178934Abstract: A microfluidic structure comprising a thermoplastic portion defining a microfluidic recess, a bonding layer on the thermoplastic portion and a siloxane elastomer portion covalently bonded to the bonding layer to seal the microfluidic recess. The microfluidic recess can therefore be formed simply, quickly and cheaply using known injection molding techniques, which are not hampered by the need for a curing step. However, the positive qualities associated with elastomers can be brought to the structure by using this to seal the microchannels. The bonding layer can be formed by silica deposited on the thermoplastic portion using techniques known in the field of optics.Type: ApplicationFiled: September 28, 2005Publication date: July 16, 2009Applicant: LANDEGREN GENE TECHNOLOGY ABInventors: Jonas Sven Peter Jarvius, Jonas Melin

Publication number: 20090178483Abstract: Methods and instruments for suppressing multiple scattering noise and extraction of nonlinear scattering components with measurement or imaging of a region of an object with elastic waves, includes transmission of at least two elastic wave pulse complexes towards the region. The pulse complexes include a high frequency (HF) and a low frequency (LF) pulse. The HF pulse is so close to the LF pulse that it observes the modification of the object by the LF pulse at least for a part of the image depth. The frequency and/or amplitude and/or phase of said LF pulse relative to said HF pulse varies for each transmitted pulse complex to nonlinearly manipulate the object elasticity observed by the HF pulse along at least parts of its propagation, and received HF signals are picked up by transducers from at least one of scattered and transmitted components of the transmitted HF pulses. The received HF signals are processed to form measurement or image signals for display.Type: ApplicationFiled: January 9, 2009Publication date: July 16, 2009Inventors: Bjorn A.J.
