*Medical Terminology pertaining to Scanning and Imaging techniques.
*Introduction to Medical Imaging*
Medical imaging is the visualization of body parts, tissues, or organs, for use in clinical diagnosis, treatment and disease monitoring.
Imaging techniques encompass the fields of radiology, nuclear medicine and optical imaging and image-guided intervention.
*What is radiology?*
It represents a branch of medicine that deals with radiant energy in the diagnosis and treatment of diseases by using imaging technologies.
This field can be divided into two broad areas:-
Diagnostic radiology
Interventional radiology
Diagnostic radiologists use medical images such as X-rays, ultrasound, CT scans and MRI scans to diagnose diseases anywhere in the body.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. Ionizing radiation
is a form of radiation that has enough energy to
potentially cause damage to DNA and may
elevate a person’s lifetime risk of developing
cancer.
3. The risk of developing cancer from medical
imaging radiation exposure is generally very
small, and it depends on:
• Radiation dose - The lifetime risk of cancer increases the larger the
dose and the more X-ray exams a patient undergoes.
• Patient’s age - The lifetime risk of cancer is larger for a patient who
receives X-rays at a younger age than for one who receives them at
an older age (hormonal status and metabolism)
• Patient’s sex - Women are at a somewhat higher lifetime risk than
men for developing radiation-associated cancer after receiving
the same exposures at the same ages.
• Body region - Some organs are more radiosensitive than others.
4. Benefits of X-ray examinations
`The discovery of X-rays represented major advances
in medicine.
X-ray imaging exams are recognized as a valuable
medical tool for a wide variety of examinations and
procedures. They are used to:
• noninvasively and painlessly help to diagnosis
disease and monitor therapy;
• support medical and surgical treatment planning;
and
• guide medical personnel as they insert catheters,
stents, or other devices inside the body, treat
tumors, or remove blood clots or other blockages.
5. Risks
• a small increase in the possibility that a person
exposed to X-rays will develop cancer later in life.
• tissue effects such as cataracts, skin reddening, and
hair loss, which occur at relatively high levels of
radiation exposure and are rare for many types of
imaging exams.
• The exact dose distribution and time !
• another risk of X-ray imaging is possible reactions
associated with an intravenously injected contrast
agent (dye), that is sometimes used to improve
visualization.
6. Principles of radiation protection:
Justification
• The imaging procedure should be judged to do more
good (e.g., diagnostic efficacy of the images) than
harm (e.g., detriment associated with radiation
induced cancer or tissue effects) to the individual
patient.
• Therefore, all examinations using ionizing radiation
should be performed only when necessary to answer
a medical question, treat a disease, or guide
procedure (intervention).
• The clinical indication and patient medical history
should be carefully considered before referring a
patient for any X-ray examination.
7. Principles of radiation protection:
Optimization
• X-ray examinations should use techniques that are
adjusted to administer the lowest radiation dose
that yields an image quality adequate for diagnosis
or intervention (i.e., radiation doses should be "As
Low as Reasonably Achievable" (ALARA)).
• The technique factors used should be chosen based
on the clinical indication, patient size, and
anatomical area scanned; and the equipment should
be properly maintained and tested.
8. Radiology and children
• children have an increased
radiosensitivity to ionizing
radiation (on average 2 - 3
times), which creates high risk,
both somatic and genetic
effects of radiation;
• physical and physiological
differences between adults and
children, including the
closeness of the bodies, as well
as irregular dynamics of their
development, lead to higher
levels of radiation children
than adults...
9. methods of limiting and reducing
radiation exposure in children
• !!!!!!! exclude unnecessary studies or those studies
in which there is no need... !!!!!
• Not subject to preventive radiological studies
children up to 14 years of age and pregnant women.
• Routine radiographs of the thorax should not be
performed simply because the baby is unhealthy.
Before making the patient images, it is necessary to
verify the presence of obvious clinical
manifestations
10. Caution- to avoid danger
Women of child-bearing age should be
questioned about possibility of pregnancy
before abdominal X-ray investigation
11. Imaging for medical purposes
Involves a team which includes the service of
• radiologists,
• radiographers (X-ray technologists),
• sonographers (ultrasound technologists),
• medical physicists,
• nurses,
• biomedical engineers, and
• other support staff working together to optimize the
wellbeing of patients, one at a time.
Appropriate use of medical imaging requires a
multidisciplinary approach.
12. The primary role of a radiologic
technologist
is using x-ray equipment to produce images of
tissues, organs, bones, and vessels and
administering radiation therapy treatments.
also called an x-ray technologist or radiographer
13. Homework survey
1. History of the discovery of X-rays
2. The physical properties of X-rays
3. Imaging mechanism (X-ray tube)
28. X-ray modalities
General method Complementary methods Contrast media
Radiography Convential linear tomography Barium meal
Fluoroscopy Decubitus Barium enema
Fluorography Cholangiography
Mammography Angiography
CT-scan Bronchography ….
29. All X-ray modalities work on the same
basic principle:
• an X-ray beam is passed through the body where
a portion of the X-rays are either absorbed or
scattered by the internal structures, and the
remaining X-ray pattern is transmitted to a
detector (e.g., film or a computer screen) for
recording or further processing by a computer.
30. X ray exams differ in their purpose:
• Radiography - a single image is recorded for later evaluation.
Mammography is a special type of radiography to image the internal
structures of breasts.
• Fluoroscopy - a continuous X-ray image is displayed on a monitor,
allowing for real-time monitoring of a procedure or passage of a
contrast agent (“dye”) through the body. Fluoroscopy can result in
relatively high radiation doses, especially for complex interventional
procedures (such as placing stents or other devices inside the body)
which require fluoroscopy be administered for a long period of time.
• CT-scan - many X-ray images are recorded as the detector moves
around the patient's body. A computer reconstructs all the
individual images into cross-sectional images or “slices” of internal
organs and tissues. A CT exam involves a higher radiation dose than
conventional radiography because the CT image is reconstructed
from many individual X-ray projections.
38. How do x-rays passing through the
body create an image?
• X-rays that pass through the body represent the
image dark (black)
• X-rays that are totally absorbed represent image
ligth (white)
__________________________________
• Air - image is dark (black)
• Metal = image is light (white)
44. Radiography
• Different views of the chest
can be obtained by changing
the relative orientation of the
body and the direction of the
x -ray beams:
• The most common views are:
1. Posteroanterior view (PA);
2. Anteroposterior view (AP);
3. Lateral
49. Basic Concepts
• One view is no view – use it all!
• Patterns are your clue
• Be sure you are looking
• Know what you’re looking for
• Know the limits of your test
50. One View is No View Posterior sulcus nodule = Cancer

59. Review: What are the 5 basic radiographic
densities from black to bright white?
• Air
• Fat
• Soft tissue/fluid
• Bone/mineral
• Metal
60. Practice: How do x-rays create an image of
internal body structures?
• X-rays pass through the body to varying degrees
• Higher atomic number structures block x-rays
better, example bone
• Lower atomic number structures allow x-rays to
pass through, example: air in the lungs
