RDGY40020 Technology of Ultrasound 2 UCD Assignment Sample Ireland

RDGY40020 Technology of Ultrasound 2 is a required course for students in the Diagnostic Medical Sonography program at University College Dublin. The course provides an introduction to the physics and technology of ultrasound, including transducers, image formation, and Doppler techniques. In addition, students learn about the principles of diagnostic medical sonography and the clinical applications of ultrasound.

Ultrasound is the use of sound waves above the human hearing range to create images. It has been used in medicine for over 50 years and is a common diagnostic tool. Ultrasound machines send sound waves into the body, and these sound waves bounce off tissues and organs to create an image on a screen.

Ultrasound machines are used to look at many different parts of the body, including the brain, heart, liver, kidneys, and stomach. They can also be used to look at unborn babies in pregnant women. Ultrasound is non-invasive and does not use radiation, so it is safe for pregnant women and children.

We’ll go through some tasks in this course. They are:

Assignment Task 1: Perform and analyze appropriate quality assurance tests.

Sonographers need to be aware of the different types of quality assurance (QA) tests available for ultrasound machines, as well as the proper way to perform and analyze these tests.

There are four main types of QA tests for ultrasound machines: mechanical index testing, phantom image quality testing, acoustic output testing, and thermal index testing.

• Mechanical index testing measures the amount of energy that is transferred from the ultrasound machine to the patient. This type of test is important to make sure that the machine is operating within its safety limits.
• Phantom image quality testing is done by using a special phantom (a man-made object that simulates a human body) to take images. These images are then analyzed to see if they meet certain standards.
• Acoustic output testing measures the sound pressure level (SPL) of the ultrasound machine. This type of test is important to make sure that the machine is not emitting harmful levels of noise.
• Thermal index testing measures the amount of heat that is generated by the ultrasound machine. This type of test is important to make sure that the machine is not generating harmful levels of heat.

All of these QA tests are important in ensuring the safety and efficacy of ultrasound machines. Sonographers should be familiar with all of these tests and know how to properly perform and analyze them.

Assignment Task 2: Justify the selection of ultrasound modes and parameters for various clinical contexts.

Ultrasound imaging is a very versatile modality that can be used for a variety of clinical indications. The different modes and parameters of ultrasound imaging allow the clinician to tailor the exam to the specific clinical problem at hand.

For example, in pregnant patients, ultrasounds are often performed using the transabdominal approach to visualize the fetus. In this case, real-time B-mode imaging with color Doppler is typically used to assess fetal anatomy and growth. Alternatively, in patients with suspected renal stones, procedural guidance during ultrasound-guided kidney stone surgery might be performed using Schwarz mode or harmonic imaging to improve visualization of stone boundaries.

The specific modes and parameters used during an ultrasound exam will vary depending on the clinical indication. The sonographer must be familiar with the different modes and parameters available in order to select the best ones for each individual patient.

Assignment Task 3: Identity, discuss and minimize ultrasound artifacts.

Ultrasound artifacts are caused by the imaging beam reflecting off of structures within the body. This can cause distortion of the image and make it difficult to interpret.

There are a few ways to minimize ultrasound artifacts:

1) Make sure you are well-positioned on the ultrasound table and that the transducer is in close contact with your skin.

2) Avoid moving during the exam. If you need to move, tell the technologist so they can pause the exam.

3) Hold your breath if possible when the image is being taken.

4) Keep still and avoid talking when images are being obtained.

5) Follow all instructions given by the technologist.

By following these tips, you can help to minimize ultrasound artifacts and improve the quality of your images.

Assignment Task 4: Analyse factors that affect ultrasound measurements.

There are a number of factors that can affect ultrasound measurements, including the type of ultrasound machine being used, the angle of the probe relative to the patient’s body, and the thickness and composition of the tissues being scanned. In addition, individual patients may vary in their physical characteristics (such as body composition), which can also affect ultrasound measurements.

It is important for sonographers to be aware of these factors when performing ultrasound exams. By taking these factors into account, they can help to ensure that accurate measurements are obtained.

Assignment Task 5: Explain the theory and practice of Doppler ultrasound.

Doppler ultrasound is a medical imaging technique that uses ultrasound to visualize the movement of blood cells in vessels. It is used to assess the flow of blood through arteries and veins and can be used to detect narrowed or blocked vessels, as well as damage to the endothelium (the thin layer of cells that line the inside of blood vessels).

Doppler ultrasound works by transmitting ultrasonic waves into a region of tissue and then measuring the frequency shift (Doppler shift) in the reflected waves. The frequency shift is caused by the movement of objects within the tissue – in this case, red blood cells – relative to the position of the probe. The faster an object moves, the greater its Doppler shift.

By measuring the Doppler shift of the reflected waves, it is possible to calculate the velocity of blood flow. This information can then be used to assess the health of the vessels and to diagnose various cardiovascular conditions.

Doppler ultrasound is a safe and non-invasive medical imaging technique that has a wide range of applications in medicine.

Assignment Task 6: Understand and apply ultrasound safety guidelines.

Ultrasound safety guidelines are important to follow in order to ensure the safety of both the patient and the ultrasound technician. Some of the key guidelines include keeping a distance from the ultrasound probe and avoiding any direct contact with it, as well as making sure that patients are not scanned for too long or at too high a power setting.

Additionally, ultrasound technicians should always be aware of their surroundings and avoid scanning people or animals who may be in close proximity. By following these simple guidelines, we can help ensure that everyone remains safe during an ultrasound procedure.

Assignment Task 7: Devise and participate in appropriate tendering and specification procedures.

When tendering for goods and services, it is important to develop a clear understanding of the needs and requirements of the project. This can be done by compiling a specification document that outlines in detail the desired outcomes, requirements, and standards that must be met by any potential suppliers.

It is also important to invite a number of suppliers to bid for the work, in order to ensure that you receive competitive rates. Evaluating proposals and selecting a supplier should be based on meeting as many of the specified criteria as possible, as well as taking into account price, experience, and references.

Assignment Task 8: Evaluate factors that affect image perception.

There are a number of factors that can affect image perception, including the type of ultrasound machine being used, the experience of the sonographer, and the patient’s body composition.

It is important for sonographers to be aware of these factors when performing ultrasound exams. By taking these factors into account, they can help to ensure that accurate measurement are made and that the images are interpreted correctly.

If you’re concerned that your image quality may be affected by some of these factors, talk to your ultrasound technician or doctor. They will be able to advise you on how to ensure that you get the best possible images.

Assignment Task 9: Explain technological innovations.

Ultrasound technology has undergone many innovative changes over the years. One of the most significant changes is in how ultrasound images are captured and displayed. In the past, ultrasound images were recorded on film. However, today, almost all ultrasound machines captured digital images onto a computer. This has made it much easier for doctors to review and share images with colleagues.

In addition, new software advancements have made it possible to enhance ultrasound images, which can help improve diagnostic accuracy. Another major innovation in ultrasound technology is 4D or real-time 3D imaging. This allows doctors to see dynamic structures within the body in three dimensions, which can be very helpful for assessing fetal development or cardiac function. 4D ultrasound also offers a dramatic improvement in image quality, making it possible to see even small details that were previously invisible.

Assignment Task 10: Locate, evaluate and analyze literature related to ultrasound technology.

Ultrasound technology is a type of medical imaging that uses high-frequency sound waves to create images of the inside of the body. It is used to examine muscles, tendons, joints, internal organs, and unborn babies.

The use of ultrasound technology has exploded in recent years due to its non-invasive nature and its ability to produce high-quality images with little radiation exposure. Ultrasound machines are now found in most hospitals and clinics, and they are also being used more and more in-home health care settings.

Ultrasound technology has many benefits, but there are some risks associated with its use as well. For example, it is not always accurate in identifying abnormalities and it can cause tissue damage if used improperly.

When considering ultrasound technology, it is important to consult with a qualified medical professional to discuss the risks and benefits. Additionally, patients should always ask their doctor or sonographer about the training and experience they have in using ultrasound equipment.
