✦ Synopsis

Needle performance is primarily judged by its penetration through tissue. For detailed studies of needle performance, tissue is too heterogeneous and unstable and difficult to obtain. A homogeneous, stable, and readily available polyurethane substrate has been evaluated as a suitable alternative to biological tissue for evaluation of needle penetration. The needle penetration profiles through the synthetic substrate correlated very well with those through natural tissue. In addition, the synthetic substrate was sensitive enough to easily detect a 20% increase in the force necessary to penetrate natural tissue. This polyurethane substrate offers a valid alternative to biological tissue for the testing of needle penetration performance.

## Abstract A formulation for ground‐penetrating radar (GPR) imaging using the synthetic‐aperture concept is introduced. We show that it is possible to form a 3D image by inverse Fourier transforming the multifrequency, multispatial scattered field. The proposed algorithm for GPR imaging is tested

New dialysis membranes, prepared from linear block copolymers, have shown unique separation properties which appear to be based on definite solut,e-membrane interaction. The synthesis and characterization of block copolyetherurethanes based on poly(oxyethy1ene glycol) is described.
