STAGE 1 - Define and target the area of clinical interest
A HistoScanning™ analysis is applied to the part of the ultrasound data that represents
the tissues of clinical interest. This is defined by the consulting clinical specialist,
radiologist or specialist ultrasonographer selecting the scan frames that contain the areas of the tissue of clinical interest. The scan frames are depicted on a
computer screen as a series of 2D grey level images (voxel data). Each frame represents
a tissue thickness of between 0.15 and 0.4 mm.
STAGE 2 -Refine and specify the data to be
analysed
Using HistoScanning's user interface tools, a Volume of Interest (VOI) is defined
and super-imposed on these images around any suspicious tissue areas. More than one VOIs can be defined in any one scan frame, including overlapping ones.
STAGE 3 -Data Analysis
HistoScanning's characterisation algorithms are applied successively to each sub-unit
within each VOI. The analysis of the results are graphically displayed as a coloured
grid overlay super-imposed on the original ultrasound scan frame. A numerical HistoScanning™
score is assigned to each frame, representing different tissue morphologies.
STAGE 4 -Report
A report file is generated to serve as a decision support tool. The report contains
the following information:
Patient ID and scan details
Histoscanning Findings
Organ, location, quality statement, score
Remarks and graphical display of the HistoScanning™ colour grid score.
Differentiated tissues are overlaid with red dots.
