PSYG06012 2023 Instrumentation and Imaging 1

Define and discuss concepts using in Clinical Measurement such as calibration testing, gain, filtering, tracing speed 

Summarise electrode types and electrode-tissue interfaces seen in Clinical Measurement Physiology

Clearly distinguish between unipolar and bipolar recordings

Explain the causes of artefact seen in recording of physiological signals and how to correct them

Show a detailed understanding of the mechanisms of various spirometry types

Describes the principles of diffusion measurement

Describe the operation of Impedance and pH sensors

Lectures will expose learners to key concepts of instrumentation and imaging as it pertains to Clinical Measurement Physiology. Work during lab practicals will offer opportunities for interactive learning in small groups through enquiry and discussion.  Practicals are designed to teach good lab technique, accurate recording of results and as problem based learning exercises to encourage teamwork

The VLE will support the module as a repository for learning material but also providing opportunities for self-directed learning through the provision of short formative assessment quizzes and activities including case study work. Module materials embrace the principles of a Universal Design for Learning approach. 

Students will be expected to actively engage with reading material and self-directed learning activities to promote integration of prior knowledge and assimilation of new specialist knowledge. 

As this module will contain elements of mathematics within the physical principles, students will be able to obtain additional support, if required, through the Maths support centre within the Centre for enhancement of Teaching and Learning (CELT).

The minimum ‘pass’ mark for this module overall is 40%. 

Assessment will include a final exam

Students will complete laboratory practicals and generate reports as a key part of ongoing assessment to apply theory to practical application and understanding. Written feedback will be provided at regular intervals as a result of this process. 

Short answer and multiple-choice quizzes will also be used

Practical assessment is centred around competent use of and understanding of clinical equipment.  This will require some flexibility in terms of week of assessment, however assessments will be carried out in labs to distribute assessment workload evenly for students

Timely assessment feedback will also be available in written format and students will be given the opportunity to discuss their feedback on submissions. 

Students will be afforded the opportunity to undertake any/all failed elements of the module at the earliest opportunity. Where the attendance of practicals is below 75%, students will be expected to offset the deficit before being regarded as having successfully completed the module.
