Geometric Accuracy in Robot-Assisted Total Hip Replacement Surgery

Computer Aided Surgery, 2003
Robot-Assisted Surgery in Total Hip Replacement (RAS-THR) has become a fairly widespread procedure for hip replacement surgery in Europe. However, data on the geometric accuracy of the overall process have so far been unavailable. The equipment manufacturers have only published data on the accuracy of certain elements of the procedure (e.g., the ...

Multifeaf collimation versus alloy blocks: Analysis of geometric accuracy

International Journal of Radiation Oncology*Biology*Physics, 1995
To compare the misalignment error due to the fabrication of custom lead alloy blocks with the displacement error introduced by the finite resolution of a multileaf collimator relative to the prescribed smooth apertures.Treatment field apertures for randomly selected patients for four clinical sites were obtained at various stages of the block ...

Geometrical Differentiation and High—Accuracy Curve Interpolation

1992
Let f be a smooth curve in ℝd, parametrized by arclength. If a large sample of data points p i = f(t i) at unknown parameter values t i < ti+1 is given, one can use local n-th degree polynomial interpolation at parameters s i = ∥P i — Pi l∥sgn(i — l) of data points P i around a fixed point P i to calculate approximations to the derivatives with ...

C‐Arm imaging for brachytherapy source reconstruction: Geometrical accuracy

Medical Physics, 2002
We study the accuracy of brachytherapy source reconstruction using C‐Arm images. We use a phantom embedded with dummy ribbons in a regular pattern, placed at the rotation center of the C‐Arm. With a commercial reconstruction jig, radiographic films are taken without the image intensifier.
