CT - PRELIM L1 Flashcards
The word Tomography is divided into two Greek words:
Tomo from the Greek word ______ which means _____
Graphy from the Greek word ______ which means ________
- Tomos
- A Cutting
- Graphia
- Writing / Drawing
An Austrian mathematician who proved that an image of
3 dimensional object could
be produced from its
mathematical projection.
Johann Radon
It is the process of creating
a cross- sectional tomographic plane of any part of the body.
Computed Tomography (CT)
It is a mathematical operator that plays a key role in various areas such as medical imaging, tomography, and even in signal processing
Radon Transform
He invented the first CT-Scan machine and was considered as the Father of CT Scan
Godfrey N. Hounsfield
He developed the
mathematical foundation
for tomographic imaging for reconstructing cross-sectional images from x-ray data
Allan Cormack
He is an Italian mathematician who proposed a method to represent a single slice of the body on the radiographic film; who’s work also helped in the mathematical methods that enable the INVERSION of the Radon transform
Allesandro Vallebona
His work involved using computers to process and reconstruct images from X-ray data, a breakthrough that laid the foundation for what would
later become the modern
CT scanner.
William Oldendorf
Hounsfield developed the first CT-Scan Machine in ______ for _________ at the ________
- 1970
- Electric and Musical Industries (EMI Ltd.)
- Central Research Laboratory in England
After CT was shown to
be a useful clinical imaging
modality, the first full-scale
commercial unit, referred
to as a ________
Brain Tissue Scanner (BTS)
He developed the first whole-body scanner, which greatly expanded the diagnostic capabilities of CT
Robert Ledley
Early CT Scan machines are called as ________
Computed Axial Tomography Scanners
The BTS was installed at _________ in ______
- Atkinson Morley’s Hospital
- 1971
Hounsfield and Cormack share the ______ Nobel Prize for ______
- 1979
- Medicine
Which generations of CT scanners were categorized by the level of technologic advancement of the tube and detector assembly ?
1st - 4th Generation CT Scan
Newer scanners are no longer categorized by generation but by ___________
Tube and Detector Movement
Consists of an x-ray source emitting finely collimated
x-ray beam and a single detector both moving
synchronously in a translate or rotate mode or a
combination of both.
CT Scanner
What are the five (5) other names of Computed Tomography:
- Computed Axial Tomography
- Computed Transaxial Tomography
- Computed Reconstruction Tomography
- Digital Axial Tomography
- Body Section Roentgenography
What are the Main Parts of a CT Scanner (8):
- Gantry Assembly
- X-ray Source
- Detectors
- Patient Table or Couch
- Computer and Display Consoles
- Workstations
- Speaker
- Mic
A vertical plane running from front to back which divides the body into left and right sections
BONUS Q: Also known as _____
Sagittal Plane
An anatomical plane used to describe the orientation of the body which divides the body into anterior and posterior portions
Coronal Plane
This divides the body into superior and inferior parts, running horizontally across the body and perpendicular to both the sagittal and coronal planes
Axial Plane
The Axial Plane is also known as the ___________
Transverse Plane
