The E.M.I. scanner is a machine which employs a method of X-raying patients whereby the information obtained from the X-rays is fully utilized. The high sensitivity thus obtained enables the machine to differentiate between the various organs of the body which are presented in three-dimensional form as a series of tomographic slices. The machine scans through the patient in a transaxial plane with a narrow beam of X-rays. A bank of detectors measures the transmission through the body as it…

Micro-computed tomography: a method for the non-destructive evaluation of the three-dimensional structure of biological specimens.

This chapter aims to review the steps necessary for a successful micro-CT measurement and provides an easy understandable manual that should allow newcomers to perform successful measurements and hence to best profit from this powerful technique.

Contributions to spectral CT

Spectral x-ray computed tomography (CT) is an important nascent imaging modality with several exciting potential applications. The research presented in this thesis separates into two primary areas

CT technology overview: 64-slice and beyond.

Recent technologic advances in multi-detector row cardiac CT.

Head Injury and the CT Scanner

The dynamic changes that occur almost daily in the evolution of damaged brain, which are faithfully recorded by the EMI Scanner, are emphasized, together with features which may be of interest to forensic pathologists.

Chest Tomosynthesis for Detection and Surveillance of Pulmonary Pathology. Studies on Cystic Fibrosis and Solid Pulmonary Nodules

The results indicate that DTS could be an alternative to CT in surveillance of patients with CF, and for follow-up of well-depicted solid nodules, including cases with progressive disease are warranted.

Multiscale imaging of the rat brain using an integrated diceCT and histology workflow

It is demonstrated that two-dimensional histology techniques can be employed on neural tissues following three-dimensional diffusible iodine-based contrast-enhanced computed tomography (diceCT) without causing tissue degradation, the first step toward a multiscale pipeline for brain visualization.

Cardiothoracic Anesthesia and Critical Care in the United Kingdom (UK) Part 1: Some Insights Into the History and Development.

The UK contributed greatly to pharmacologic interventions that were unique at the time in such varied areas as nonflammable volatile anesthetic agents, heart failure treatments, and neuromuscular blocking agents for both cardiac and thoracic surgical practice.

Wrong site neurosurgery – still a problem

There was little consistency, both within and between units, to the response to the Patient Safety Alert, and an audit of the 36 hospitals providing neurosurgery in Great Britain and Ireland in 2005 received a 94% response rate, which was considered low.
