history of ct scan

1917-J RADON,WORKING WITH GRAVITATIONAL THEORY
Proved that an image of an unknown object could be produced if one had an infinite number of projections through the object
1956-BRACEWELL WORKING IN RADIOASTRONOMY
1961-OLDENDORF UNDERSTOOD CONCEPT OF CT
1972-G.N.HOUNSFIELD PUT A CT SYSTEM TOGETHER.

CT was originally proposed and used as an extension of the basic X-ray: doctors wanted to see inside the head, but standard X-ray t ....etc

Blood tests look at liver function and levels of tumor markers (certain substances which are linked to specific types of cancer). Liver tumors will often show on an ultrasound scan but full assessment requires a CT (computerized tomography) scan or MRI (magnetic resonance imaging) scan.
n general, the imaging appearances of liver metastases are nonspecific, and biopsy specimens are required for histologic diagnosis. CT is the imaging modality of choice for evaluating liver metastases. This preference is largely attributable to the effects of t ....etc

IRIS SCAN AND BIOMETRICS
Bio Medical Electronics Seminar Topic

ABSTRACT

A method for rapid visual recognition of personal identity is described, based on the failure of statistical test of independence. The most unique phenotypic feature visible in a person s face is the detailed texture of each eye s iris: an estimate of its statistical complexity in a sample of the human population reveals variation corresponding to several hundred independent degrees-of-freedom. Morphogenetic randomness in the texture express ....etc

A computerized tomography (CT) scan combines a series of X-ray images taken from different angles and uses computer processing to create cross-sectional images, or slices, of the bones, blood vessels and soft tissues inside your body. CT scan images provide more detailed information than plain X-rays do. ....etc

Biometrics refers to the automatic identification of a person based on his/her physiological or behavioral characteristics such as finger scan, retina, iris, voice scan, and signature scan etc. This method of identification is preferred over traditional methods involving passwords and PIN numbers for various reasons: the person to be identified is required to be physically present at the point-of-identification; identification based on biometric techniques obviates the need to remember a password or carry a token. The ultimate form of electroni ....etc

Using a Hash-Based Method with Transaction Trimming and Database Scan Reduction for Mining Association Rules

Presented By:
Jong Soo Park, Ming-Syan Chen and Philip S. Yu

Abstract

In this paper, we examine the issue of mining association rules among items in a large database of sales transactions. Mining association rules means that given a database of sales transactions, to discover all associations among items such that the presence of some items in a transaction will imply the presence of other items in the same trans ....etc

ABSTRACT
Over the last few years a new area of engineering science has been established whose products are likely to create a large market in the near future. It has been called ''biometrics. The pioneers of this new domain intend to construct devices which would allow identification of a person on the basis of his/her ''biological'' characteristics: voice, dynamics of movements, features of face and other parts of the body, retina or iris pattern.
The paper gives an overview of fingerprint technology in biometrics. Fin ....etc

INTRODUCTION

X-ray computer tomography and computed tomography (CT) or computerized tomography (CAT scan) is a medical imaging procedure that uses computer processed x-rays to produce a tomographic images or slices of specific parts of the body. These cross-sectional images are used for diagnostic and therapeutic purposes in various areas of medicine. Medical device (apparatus), is called CTG scanner, this is a great machine and uses x-rays.

That's actually a CT.. ??

CT produces a volume of data that can be manipulated through a process ....etc
