Definitions

  • the following describes an approach that in one instance displays 2- D pre-scan projections images using different rendering algorithms to visually enhance a region/tissue of interest in a displayed 2-D pre-scan projection image, where the region/tissue of interest is determined from the scan protocol.
  • the 3-D volume scan of the region/tissue of interest is performed based on the 3-D volume scan plan.
  • FIG. 10 shows a lateral lung MIP 2-D pre-scan projection image created from data acquired during a 3-D pre-scan and a scan plan or bounding box, in accordance with an embodiment(s) herein.
  • the reconstructor 316 is implemented with hardware such as a central processing unit (CPU), a microprocessor (pCPU), a graphics processing unit (GPU), an application specific integrated circuit (ASIC), etc. configured to execute computer executable instructions stored, embedded, encoded, etc. on computer readable storage medium and/or non- transitory memory.
  • the reconstructor 316 can be part of the system 302 (as shown) and/or remote therefrom, e.g., in a remote computing system, distributed across other computing systems, part of“cloud” based resources, etc.
  • the computer readable instructions include at least 3-D data acquisition instructions and reconstruction instructions.
  • suitable data acquisitions include 2-D pre-scans and/or 3-D pre-scans, and diagnostic 3-D volume scans.
  • suitable reconstructions include a 2-D pre-scan projection image from the data acquired with the 2-D pre-scan and/or a 2-D pre-scan projection image from the data acquired with the 3-D pre scans, and a diagnostic 3-D volumetric image data from data acquired from a diagnostic 3-D volume scan.
  • Suitable rendering algorithms include algorithms for projecting 3-D data into a 2- D plane.
  • Non-limiting examples includes, but are not limited to, MIP, ST Edge, Minimum Intensity Projection (MinIP) which is the negative of MIP and projects the voxel with the lowest intensity, Multiplanar Reconstruction (MPR) which reformats the volumetric to generate a 2-D pre-scan projection image in a axial, sagittal, coronal, and/or oblique plane, curved MPR (cMPR) which effectively straightens a curved structure (e.g., the spine, vessels, etc.) so that the entire length of a section or the entire curved structure is concurrently visualized in the same plane, and/or other volume rendering techniques.
  • MIP Minimum Intensity Projection
  • MPR Multiplanar Reconstruction
  • cMPR curved MPR
  • a 3-D volume scan of the region/tissue of interest is performed based on the scan plan for the 3-D volume scan, as described herein and/or otherwise.
