All welcome. Download pdf flyer.

Exhibits

We plan to host the following exhibits:

1. UCLH Medical Physics and Bioengineering: 3D scanner/craniofacial models

The Medical Graphics Laboratory does a lot of work with faces: in some cases, we scan them on the surface, in other cases we work with CT scans of the bones beneath the face. Once we have these scans, we work with surgeons and other clinical colleagues to devise repairs and advise on procedures for repairing problems. These problems can be as severe as a hole in the head.

2. Photoacoustics and biomedical ultrasound

Photoacoustics is a promising new method of non-invasive biomedical imaging based upon the use of laser-generated acoustic waves for visualising the internal structure and function of soft tissues. Potential applications include the clinical assessment of breast cancer, vascular disease and skin abnormalities.

3. Optical Topography

Optical Topography combines the ease-of-use, low cost and portability of EEG with  the imaging capabilities of MRI. It uses near-infrared light to carry out functional imaging of the brain in real time. An array of optical fibres placed on the scalp measures cortical changes in blood volume and oxygenation using the characteristic infrared absorption spectra of oxygenated and deoxygenated haemoglobin.

4. UCLH Radiotherapy Physics

The Department strives to be at the cutting edge of technology to deliver high precision, highly conformal Radiotherapy treatments for cancer patients. We were among the first institutions in the UK to introduce both intensity X-ray Modulated Radiotherapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT) techniques, in conjunction with improved accuracy in delineation and localisation of tumours by registering MRI, PET/CT and now PET/MR with planning scans.

5. Proton radiotherapy

UCLH will host a cutting edge new proton therapy centre which aims to begin to treat patients in 2016. Proton therapy is an advanced radiotherapy technique which is able to target a tumour while minimising radiation dose to surrounding tissues. It is particularly well suited for difficult to treat tumours (e.g. head and neck, and spine) and where is is particularly important to reduce dose to other organs (e.g. in children).

6. Absorbent incontinence product components

The Continence and Skin Technology Group has dedicated the last 30 years to developing an international programme of work to understand and address the most important issues for incontinent people, caregivers and manufacturers of products. Recent experimental research has focused on components of absorbent products used for the management of incontinence. We will be displaying some of these products and video clips of experiments, as well as demonstrating the purposes of two of the main components: superabsorbent polymers and nonwoven fabrics. There will also be the opportunity to measure the rate of water loss from your skin – an important factor in assessing behaviour of the skin when it interacts with the topsheet of an absorbent product!

7. Radiation physics Group: Diffraction and phase contrast imaging

X-Ray Diffraction imaging and X-Ray Phase Contrast imaging are two important research areas within the Radiation Physics group. Both imaging techniques find applications in various fields, such as medical imaging, non-destructive testing and security scanning. We will demonstrate how the two techniques work by showing explanatory posters together with equipment from the Radiation Physics Laboratories at UCL.

8. Implanted devices 

Research in the Implanted Devices Group is aimed at restoring function to paralysed muscles using Functional Electrical Stimulation, FES.

9. Centre for medical image computing: Laparoscopic image guidance

The Centre for Medical Image Computing combines excellence in medical imaging sciences with innovative computational methodology. Our research finds application in biomedical research and in healthcare with a particular emphasis on translation of new computational methods in imaging sciences to the clinic.

10. Localisation of a goldfish in a tank with electrical impedance tomography

Electrical Impedance Tomography is a recently developed imaging technique, with which images of the internal impedance of the subject can be rapidly collected with rings of external ECG-type electrodes. It is fast, inexpensive, portable and sensitive to physiological changes which affect electrical impedance properties.

11. Teaching and research information and handouts
