Stress-strain data obtained from animal and human tissue have several applications including medical diagnosis, assisting in surgical instrument design and the production of realistic computer-based simulators for training in minimal access surgery. Such data may also be useful for corroborating mathematical models of tissue response. This paper presents(More)
This paper describes an objective quality measure for image sequences based on a model of the human visual system (HVS). When developing an appropriate HVS based model it is important to consider the structure of the pictures and of the coding errors introduced by the compression scheme. This is because they are both unlike the simple and artificial stimuli(More)
Cone beam computed tomography (CBCT) is used widely for the precise and accurate patient set up needed during radiation therapy, notably for hypo fractionated treatments, such as intensity modulated radiation therapy and stereotactic radiation therapy. Reported doses associated with CBCT indicate the potential to approach radiation tolerance levels for some(More)
PURPOSE Minimally invasive treatment of solid cancers, especially in the breast and liver, remains clinically challenging, despite a variety of treatment modalities, including radiofrequency ablation (RFA), microwave ablation or high-intensity focused ultrasound. Each treatment modality has advantages and disadvantages, but all are limited by placement of a(More)
The use of parameters water equivalent diameter (D W ) and size-specific dose estimate (SSDE) are becoming increasingly established as a recognised method to relate patient dose from a CT examination to the dose indicator volume CT dose index (CTDIVOL). However, the role of the attenuation due to the patient table in these estimations requires careful(More)
an international code of practice for diagnostic radiology (now known as TRS457 [1]). At the time it appeared to me that there was little new or special. Now, over 10 years later, I find I need to review this assumption. From my perspective much has changed in the last decade. The perception of the importance of diagnostic radiology dosimetry has broadened.(More)
BACKGROUND Goal setting is considered 'best practice' in stroke rehabilitation; however, there is no consensus regarding the key components of goal setting interventions or how they should be optimally delivered in practice. We developed a theory-based goal setting and action planning framework (G-AP) to guide goal setting practice. G-AP has 4 stages: goal(More)
