Malignant tumors have different cells in different parts: necrotic (dead) in some parts, pre-cancerous in other parts, and cancerous cells which will be diagnosed
as such (in pathology examination) in some parts. When performing FNA procedure, it is important to extract cancerous cells within the extracted tissue sample. Extracting such cells can be difficult, considering the fact that ultrasound guidance is two dimensional while the lesion is three dimensional,
couples with the tendency of a single needle to be pulled towards its previous (now empty) tract and reach the same sampling site. This means that a sample
taken with an EUS-FNA needle is not guaranteed to correctly diagnose a lesion as malignant (or benign).
The purpose of this project was to allow extraction of a more representative sample of tissue, collected from different areas of the tumor
in a 3-dimensional spread.
