HECS5174M Advancing of Science & Technology of Medical Ultrasound

This module is not approved as an Elective

Objectives

On completion of this module, students will be able to demonstrate an in-depth specialist knowledge, understanding and mastery of the core and advanced scientific principles and technology used in medical ultrasound imaging.

Learning outcomes
On completion of this module, students will be able to:
- Critically evaluate and debate the advancing safety issues related to diagnostic imaging to enable optimal use of the equipment within the current, internationally recognised recommendations for safe practice actively reducing any hazard to patient and staff
- Critically evaluate the role of advancing image processing for your area of imaging practice
- Demonstrate an in-depth specialist knowledge of advancing diagnostic image recording & display equipment
- Critically evaluate the significance, performance and interpretation of advancing quality assurance techniques appropriate for your area of clinical imaging practice
- Critically appraise the significance of advancing new science and technology developments in diagnostic imaging in your area of imaging practice in order to identify and select new machines for replacement.

Skills outcomes
Contextualise and critically evaluate science and technology theoretical knowledge

Critically reflect on the application of science and technology in clinical practice

Identify the compromises inherent in the production of a high quality image and critically evaluate the role of the operator in using the controls to optimise the process

Identify and develop multi-professional collaboration skills in doing, analysing and critically evaluating science and technology practical tests.

Private study

During the 2 contacts weeks, days are set aside for private study / independent learning. These days and at other times during the module the type of private study will include reading, literature searches, and tutorial and assessment preparation.

During the contact weeks the students will be given small pieces of private study / practical tasks which must be brought to the tutorial sessions. This will form feedback material for the multidisciplinary group tutorial sessions.

The lecture PowerPoint presentations and e-learning facilities will be available via VLE to review before and after each session.

Opportunities for Formative Feedback

During the module the students will be required to undertake course work. This will help develop the students learning and prepare them for the Summative assessment.

This will take the form of:
- Tutorial problem solving tasks
- Formative unseen written examination-March
- Academic supervision for practical report
- Involvement and participation in group work around the topics introduced will help develop learning and be in preparation for the summative assessment.

In addition, the students will be strongly encouraged to arrange individual tutorials and discuss their outline of the assignments with the academic supervisor.
