A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity ...and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon Collider Collaboration. This Review summarises the status and the recent advances on muon colliders design, physics and detector studies. The aim is to provide a global perspective of the field and to outline directions for future work.
An echographic method for investigating biological tissue internal structure in order to differentiate pathological regions is proposed in this work. The method, named RULES (radiofrequency ...ultrasonic local estimator), is based on interactive radiofrequency (RF) echographic signal processing. It permits to extract spectral parameters related to the actual organization and mechanical properties of investigated tissue. Spectral images are produced through a processing procedure, based on a statistical analysis of local estimators (LE). They are calculated from the spectral coefficients of discrete wavelet packet transform. The tissue portions, which exhibit the same LE homogeneous distribution, were put in correspondence with condition and type of tissue identified by histological studies. Results obtained on prostate pathology detection, breast tumor detection and carotid vessel plaque localization and differentiation are presented.
An echographic method for differentiating pathological regions in biological tissue was proposed previously (Masotti, L. et al., Proc. IEEE Ultrason. Symp., p.1030-3, 2003). The method, named RULES ...(Biagi, E. et al., Italian Patent FI2003A000254, 2003; Italian Patent FI2002A34, 2002; European Patent 03425118.1, 2003; US Patent 10/383674, 2003), is based on radiofrequency (RF) echographic signal processing. It permits spectral parameters related to the organization and mechanical properties of investigated tissue to be extracted. Spectral images are produced through a processing procedure, based on the discrete wavelet packet transform. A hardware-software platform, FEMMINA (fast echographic multiparameter multi image novel apparatus) (Scabia, M. et al., IEEE Trans. UFFC, vol.49, no.10, p.1444-51, 2002), for real-time signal and image processing was employed in order to test the diagnostic applicability of the method. The results for breast tumor detection and characterization are presented together with the results from a clinical investigation on the prostate, where the RULES features are employed for localizing pathological zones in order to guide bioptical sampling.
