Event details

The meeting will showcase the range and diversity of imaging available for life sciences research. Programme for Thursday 19th April 2018, 19/3011, Highfield Campus, University of Southampton:

9.00 – 9.30 Registration

9.30 – 10.00 Introduction to the Biomedical Imaging Unit and µ-VIS . Overview of imaging at the University of Southampton and in particular the two imaging core facilities. Dr Anton Page & Dr Philipp Schneider

10.00 - 10.45 Key Note Presentation. Interfaces, challenges and potential applications of micro-CT technology within pathology: A pathologist’s perspective. Dr Ciaran Hutchinson

The session will consider some of the practical, diagnostic and conceptual challenges faced within histopathology practice; emerging areas of research regarding the use of micro-CT technology within pathology, and some of the challenges to clinical adoption of micro-CT as part of routine pathological assessment.

10.45 – 11.15 Coffee

11.15 – 11.30 Technical presentation. X-ray micro-CT as a tool for 3D x-ray histology. Dr Orestis Katsamenis

Microfocus x-ray computed tomography (μCT) is a powerful non-destructive 3D microscopy technique that is particularly popular in biomedical imaging. We recently demonstrated that, despite the general perception, the technique can be applied on routinely prepared wax-embedded histological specimens, in a clinical setting to assist diagnosis in fields of histopathology. We envisage that in the near future this technology will be readily available alongside conventional microscopy techniques, providing high resolution volume imaging and quantification capabilities that would improve accuracy of diagnosis.

11.30 – 11.45 Technical presentation. Slicing biology by fluorescence. Dr David Johnston

Confocal and light sheet microscopy produce optical slices within three dimensional biological material, allowing 3D datasets to be generated. Both techniques can work simultaneously with multiple fluorescent labels, allowing multichannel / multi probe localisation studies.

11.45 – 12.05 Application presentation. TBA

12.05 – 12.25 Application presentation. 3D analysis of Retinal Pigment Epithelial cells: insights into the aged and diseased retina. Dr Arjuna Ratnayaka

Degeneration of the Retinal Pigment Epithelium (RPE), which maintains the overlying neuroretina, is a key event leading to irreversible sight loss. Although many structural and physiological changes associated with RPE dysfunction has been elucidated, it has not resulted in developing effective treatments against blinding retinopathies. Here, for the first time, we use serial block-face scanning electron microscopy (SBFSEM) to reconstruct the RPE in 3D. This has provided altogether new information on their structural organisation as well as insights into how some RPE cells may be particularly susceptible to disease.

12.25 – 13.25 Lunch

13.25 – 13.40 Technical presentation. High resolution 3D imaging by electron microscopy. Dr Anton Page

An overview of serial block-face scanning electron microscopy (SBFSEM) and electron tomography (an extension of traditional transmission electron microscopy) which is facilitating imaging of tissues, cells and sub-cellular structure in 3D at the ultrastructural level.

13.40 – 14.00 Technical presentation. Image processing & data management. Drs Richard Boardman & David Chatelet

Datasets generated by digital imaging techniques, particularly 3D, can be large and cumbersome. Here we look at how these can be reduced to a more manageable size, and how they can and should be looked after once you have generated them.

14.00 – 14.20 Application presentation. Correlative imaging of bone in 3D. Patricia Goggin

Understanding the structure of osteocytes may help us to better understand how bone senses and responds to mechanical loads and how bone diseases develop. 3D images of the detailed structure of osteocytes and the bone around them would help to explain these mechanisms. This project aims to develop a method combining light, X-ray and electron microscopy techniques to image osteocytes in fine detail and over large volumes.

14.20 – 14.40 Application presentation. 3D correlative imaging of soft tissue and digital signal processing using micro-focus X-ray computed tomography. Mat Lawson, Stephanie Robinson & Harry Rossides

Research applications that utilise versatile imaging techniques to obtain accurate 3D structural and cellular detail in soft tissue and allow for virtual 3D manipulation of the resulting reconstructions.

14.40 – 15.10 Coffee and discussion
