- Sources of error in comparing functional magnetic resonance imaging and invasive electrophysiological recordingsD L Hill
Radiological Sciences, Guy s Hospital, King s College London, United Kingdom
J Neurosurg 93:214-23. 2000..The authors have conducted a similar study, and in this paper they identify and quantify two characteristics of these data that can make such a comparison problematic...
- Medical image registrationD L Hill
Radiological Sciences, King s College London, Guy s Hospital, UK
Phys Med Biol 46:R1-45. 2001..Nevertheless many registration problems remain unsolved, and this is likely to continue to be an active field of research in the future...
- Augmentation of reality using an operating microscope for otolaryngology and neurosurgical guidanceP J Edwards
RADIOLOGICAL SCIENCES DEPARTMENT, UMDS, Guy s Hospital, London, United Kingdom
J Image Guid Surg 1:172-8. 1995..Measurements with a head phantom gave a root mean square (RMS) error of 1.08 mm, and the estimated error for a human volunteer is between 2 and 3 mm. Initial evaluation in the operating room was very promising...
- Feasibility study of magnetic resonance imaging-guided intranasal flexible microendoscopyD L Hill
Division of Radiological Sciences, UMDS, Guy s Hospital, London, United Kingdom
Comput Aided Surg 2:264-75. 1997..Intraoperative display was provided in the scanner room by means of an liquid crystal display (LCD) projector. We estimate the accuracy of the endoscope tracking to be approximately 2 mm...
- A three-component deformation model for image-guided surgeryP J Edwards
Computational Imaging Science Group, Radiological Sciences, UMDS, Guys Hospital, London, UK
Med Image Anal 2:355-67. 1998..This paper presents the problem of tissue deformation, which has received little attention in the literature and outlines the framework we have developed for tackling this difficult subject...
- Validation of a two- to three-dimensional registration algorithm for aligning preoperative CT images and intraoperative fluoroscopy imagesG P Penney
Computational Imaging Science Group, Division of Radiological Sciences, Kings College London, Guy s Hospital, London Bridge, London, SE1 9RT, United
Med Phys 28:1024-32. 2001..90 mm. These errors approximately relate to a two-dimensional projection error of 1.3 mm. The failure rate was less than 8.3% for three of the four data sets. However, for one of the data sets a much larger failure rate (28.5%) occurred...
- Nonrigid registration using free-form deformations: application to breast MR imagesD Rueckert
Division of Radiological Sciences and Medical Engineering, Guy s, King s, and St Thomas School of Medicine, King s College London, Guy s Hospital, London, UK
IEEE Trans Med Imaging 18:712-21. 1999..The results clearly indicate that the nonrigid registration algorithm is much better able to recover the motion and deformation of the breast than rigid or affine registration algorithms...
