WebNov 4, 2024 · Imaging intact human organs from the organ to the cellular scale in three dimensions is a goal of biomedical imaging. To meet this challenge, we developed hierarchical phase-contrast tomography (HiP-CT), an X-ray phase propagation technique using the European Synchrotron Radiation Facility (ESRF)'s Extremely Brilliant Source (EBS). WebWe applied HiP-CT to image five intact human parenchymal organs: brain, lung, heart, kidney and spleen. These were hierarchically assessed with HiP-CT, providing a structural overview of the whole organ alongside detail of the organ's individual functional units and cells.

WebAn emerging technology—a prototype x-ray technique called hierarchical phase contrast tomography (HiP-CT)—decouples field of view and resolution to yield images of the human body at the micron level. The 3D map of intact organs at cellular magnitude could proffer a foundational comprehension of system-level interactions intrinsic in pathology. WebJun 1, 2014 · Total amount of contrast. In many protocols a standard dose is given related to the weight of the patient: Weight < 75kg : 100cc. Weight 75-90kg: 120cc. Weight > 90kg : 150cc. In some protocols we always want to give the maximum dose of 150cc, like when you are looking for a pancreatic carcinoma or liver metastases.
