摘要:

医学成像是医学中的宝贵资源,因为它能够窥视人体内部,并为科学家和医生提供理解,建模,诊断和治疗疾病所不可或缺的丰富信息。重建算法需要将采集硬件收集的信号转换为可解释的图像。重建是一个具有挑战性的任务,给定的不适定的问题,并在实际情况下,没有精确的解析逆变换。虽然在过去的几十年里,在新的模式、提高的时间和空间分辨率、降低的成本和更广泛的适用性方面取得了令人印象深刻的进步,但仍然可以设想一些改进,例如减少采集和重建时间,以减少患者暴露于辐射和不适,同时增加诊所的吞吐量和重建精度。此外,在具有小功率的手持设备中部署生物医学成像需要在准确性和延迟之间保持良好的平衡。

英文摘要:

Medical imaging is an invaluable resource in medicine as it enables to peer inside the human body and provides scientists and physicians with a wealth of information indispensable for understanding, modelling, diagnosis, and treatment of diseases. Reconstruction algorithms entail transforming signals collected by acquisition hardware into interpretable images. Reconstruction is a challenging task given the ill-posed of the problem and the absence of exact analytic inverse transforms in practical cases. While the last decades witnessed impressive advancements in terms of new modalities, improved temporal and spatial resolution, reduced cost, and wider applicability, several improvements can still be envisioned such as reducing acquisition and reconstruction time to reduce patient's exposure to radiation and discomfort while increasing clinics throughput and reconstruction accuracy. Furthermore, the deployment of biomedical imaging in handheld devices with small power requires a fine balance between accuracy and latency.
