As per the UKRI portfolio and priorities, this project falls within the EPSRC Medical imaging -including medical image and vision computing research area.In the rapidly advancing field of medical image analysis, there is a growing need for robust and reliable tools to aid in clinical decision-making. The increasing complexity of imaging data, coupledwith the inherent uncertainty in medical diagnostics, outlines the significance of a better understanding of uncertainty measurements in medical image analysis. The research project aims to address this critical gap by delving into the realm of uncertainty in medical image analysis, withthe ultimate goal of improving the accuracy and reliability of diagnostic outcomes using additionallinguistic information.In general, modern advancements in medical image processing have derived from the use ofartificial intelligence (AI) which learns from a set of training data. Once the model has beentrained, it is then queried with new unseen data so that we can assess it's performance and evaluate deploying the model to use in the real-world. The term for this AI in the context of 2D and 3D images is called computer vision and encompasses how computers understand the semantics of imaging data.Rapidly growing advancements in computer vision applications have been leveraging powerfultools from other areas of deep learning such as from Natural Language Processing (NLP) which uses AI to understand and act on language information. As a result, training procedures and models are improving. For example, transformers which are a cutting edge methodology to understand language, utilise auxiliary problems when training. These are alternative sub problems that the model is trained on that have been proven to improve the performance on the original primary problem.Additional existing research can highlight anomalous regions of a scan without using labelledtraining data to say "this region is anomalous and contains a glioma". This is referred to asunsupervised learning and generally involves using a generative model such as a VAE, GAN ordiffusion model to recreate the image from a compressed representation of the image. Consequently this allows us to lean in to the limited anomalous data that may be available from a medical perspective.Aims1. Evaluate the robustness of existing uncertainty measurements in medical image analysis.2. Quantify the impact of uncertainty on diagnostic accuracy and clinical decision outcomes.3. Explore the application of uncertainty-aware models in diverse medical imaging modalities,such as MRI, CT, and X-ray.4. Investigate the consequence adding natural language has on the uncertainty on clinical diagnostic accuracy.

根据UKRI的投资组合和优先事项，该项目福尔斯属于EPSRC医学成像-包括医学图像和视觉计算研究领域。在快速发展的医学图像分析领域，越来越需要强大可靠的工具来帮助临床决策。随着医学影像数据复杂性的增加，以及医学诊断中固有的不确定性，更好地理解医学影像分析中的不确定性度量具有重要意义。该研究项目旨在通过深入研究医学图像分析中的不确定性领域来解决这一关键差距，最终目标是使用额外的语言信息来提高诊断结果的准确性和可靠性。一般来说，医学图像处理的现代进步源于人工智能（AI）的使用，它从一组训练数据中学习。一旦模型被引入，它就会被新的看不见的数据查询，这样我们就可以评估它的性能，并评估部署模型在现实世界中的使用。在2D和3D图像的背景下，这种人工智能的术语被称为计算机视觉，包括计算机如何理解成像数据的语义。计算机视觉应用的快速发展一直在利用其他深度学习领域的强大工具，例如自然语言处理（NLP），它使用人工智能来理解和处理语言信息。因此，培训程序和模式正在改进。例如，transformers是一种理解语言的尖端方法，在训练时使用辅助问题。这些是模型训练的替代子问题，已被证明可以提高原始主要问题的性能。其他现有研究可以突出显示扫描的异常区域，而无需使用标记的训练数据来说明“该区域异常并包含胶质瘤”。这被称为无监督学习，通常涉及使用生成模型，如VAE，GAN或扩散模型，从图像的压缩表示中重新创建图像。因此，这使我们能够倾向于从医学角度获得的有限的异常数据。评估现有医学图像分析中不确定度测量的鲁棒性.量化不确定性对诊断准确性和临床决策结果的影响。探索不确定性感知模型在MRI、CT、X射线等多种医学成像模式中的应用。研究增加自然语言对临床诊断准确性不确定性的影响。
