Abstract: A percutaneous guidewire comprising a distal end portion that is pre-formed in a curve that turns through more than 270 degrees. The stiffness of the guidewire may decrease continuously along the length of the curved distal end portion towards the tip of the guidewire and the radius of curvature of the curved distal end portion may also decrease towards the tip of the guidewire.

Abstract: A phantom, and a method and system for scanning the phantom, is provided for assessing the performance of ultrasound scanners. The phantom has tissue mimicking material (TMM) sections with different backscatter properties. The resolution of the scanner is assessed by measuring the response of the system to a step change in backscatter. Penetration and sensitivity of the scanner can also be assessed by measuring backscatter properties. Layers of the phantom can comprise lesions to enable quantification of the lesion detection performance of the scanner. The scanner can also comprise regularly spaced targets to enable assessment of the distance measurement accuracy of the scanner.

Abstract: The invention provides an imaging system using an inherently non-imaging detection probe, linked to a, position and optional contact-sensing device, for use in scanning a surface having a surface radiation flux. The system has processing means to take signals from the detection probe and sensing devices, and to create an image of the geometry of the surface, and of the surface radiation flux. The system also provides means to determine the depth of a radiation source below the surface. The system also has means to present this image to a user.
