Rectilinear scanner
Rectilinear Scanner
A Rectilinear Scanner (pronounced: rec-ti-lin-ear scan-ner) is a type of medical imaging device used primarily in nuclear medicine to capture images of internal body structures. The term originates from the Latin words 'rectus' meaning straight and 'linea' meaning line, referring to the straight line scanning pattern of the device.
Function
The Rectilinear Scanner operates by moving a single detector in a straight line across the body, capturing a series of images that are then combined to form a complete picture. This method of scanning is particularly useful in radiology and oncology, where it can help to identify tumors and other abnormalities.
History
The Rectilinear Scanner was first developed in the 1950s as a way to improve upon the existing planar imaging techniques. It was one of the first devices to allow for the visualization of internal body structures without the need for invasive procedures.
