Brief Handbook Description: Biomedical imaging technology is a fundamental element of both clinical practice and biomedical research, enabling the visualisation of biological characteristics and function often in a non-invasive fashion. The advancement of digital scanning technologies alongside the development of computational tools has driven significant progress in medical image analysis tools that support clinical decisions and the analysis of data from biological experiments. The focus of this unit will be the development of fundamental computational skills and knowledge in biomedical imaging, including data acquisition, formats, visualisation, segmentation, feature extraction, and machine learning based image analysis.

On completion of this unit, students will be able to engineer and develop solutions for different biomedical imaging tasks encountered across a variety of use cases: clinical practice (e.g., computerised disease detection and diagnosis), research (e.g., cell video analysis), and industry (e.g., fabrication of customised implants from patient image data).
Assumed Knowledge: An understanding of biology (1000-level), experience with programming (ENGG1801, ENGG1810, BMET2922 or BMET9922).

# Activity Name Hours per Week Sessions per Week Weeks per Semester

T&L Activities: Lectures will focus on examining different aspects of biomedical image analysis.

Tutorials will provide an opportunity to consolidate theoretical knowledge from lectures through exercises.

Laboratories (in computer labs) will provide an opportunity to translate theoretical knowledge into practice through the implementation of biomedical image analysis techniques. Most labs will have a challenge-driven structure: students will be given a set of problems and will have to creatively apply the knowledge of image analysis that have gained to address those problems.

Independent study will be necessary to review and consolidate weekly lecture material, complete tutorial or laboratory exercises, and to complete assessment tasks.

Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.

Attribute Development Method Attribute Developed
Students are required to understand and explain the mathematical theories behind image analysis algorithms, both in laboratory exercises and in practical assessments. Based on these theories, students will have to rationally select the appropriate algorithms for the specific problem. (1) Maths/ Science Methods and Tools (Level 3)
Students are given scenario(s) that require them to use various components and tools to create a pipeline to process a set of medical imaging data. Students have to implement and construct appropriate methods & tools given the requirements and constraints in the given setting. (2) Engineering/ IT Specialisation (Level 4)
Students design and implement a pipeline of image analysis processes. They will describe the integration of these processes to encompass a software framework for specific application scenarios, identifying both strengths and limitations, and how these can be addressed through new inventions in research literature. (3) Problem Solving and Inventiveness (Level 3)
Students are required to perform requirements analysis through the practical assessment. They have to identify implicit & explicit requirements in a given project brief, and how they translate to different software functions.

Students are required to practice their written and oral communication skills through the assessments. They need to articulate the technical means through which their software addresses a given problem, and the justification for their design decisions. They should be able to discuss and draw insights from the experimental results gathered from the performance analysis of their implemented software.
(6) Communication and Inquiry/ Research (Level 4)

For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table 2018.

Assessment Description: • Assignment: Image Processing – students will implement a software tool for processing medical image data (e.g., performing segmentation), preparing a brief report on its performance. The software functionality and the associated analysis in the report will be assessed.

• Quiz – a paper-based mid-semester quiz covering materials from lectures, tutorials, and laboratories.

• Assignment: Classification – students will implement a software tool for making a diagnostic prediction from medical image data, preparing a brief report on its performance. The software functionality and the associated analysis in the report will be assessed.

• Written exam: Final examination covering all materials in lectures, tutorials, laboratories, and assignments.
Assessment Feedback: The teaching team will provide feedback on the assessment tasks. Assignment results will be published on Canvas. Students are required to check their results. Any errors or omissions must be reported to the unit coordinator, with appropriate evidence, within 5 working days (a week) of being published; 5 days after being published, marks are considered to have been confirmed and will not subsequently be altered.
Policies & Procedures: This course will use text-based similarity detecting software (Turnitin) for all text-based written assignments. Deadlines for assignments are set on the assumption that students may experience minor setbacks caused by sickness, computer breakdown etc. In this context, ‘minor’ means ‘causing a delay of up to three working days’. Extensions will not be granted for minor setbacks.

Late work will incur a penalty of 5% of the total marks per day (or part thereof); work that is more than 10 days late will not be marked. Students who have a genuine misadventure should make an application for Special Consideration.
