Look Up Tables in Radiography: What Are They?

look up table x-ray analysis

What are look up tables in radiography? The gray-scale values in a digital image consist of binary numbers. It is possible to reassign these numbers to other values based on predetermined rules. These rules are defined in a look-up table (LUT) which is essentially a reference histogram. A look-up table (LUT) is a series of mathematical equations that are used for post-processing in radiography. It is used to correct values using a mapping function. It allows the gray-scale values in the recorded image to be remapped to new values to improve the final image in some way, such as appropriate brightness and contrast. LUTs are specific to anatomic areas.

OPTO-ACOUSTIC BREAST IMAGING

Schematic representation of opto-acoustic breast imaging

Opto acoustic breast imaging is a new generation diagnostic tool currently in the clinical trial stage for diagnosis of malignant or benign breast lumps. According to a European journal of breast cancer around 4 million new cases of breast cancer are detected every year with almost 80 percent of them turning out to be benign on laboratory testing. It is difficult for radiologists to rule out malignancy at the imaging stage. The cost of conducting surgical or core needle biopsy for every suspicious lump outweighs the results especially in women coming from struggling economies. A low cost diagnostic tool such as opto acoustic imaging can help in the timely detection of breast cancer in the early stages and also help prevent and control the increasing mortality due to this disease in developing as well as developed countries.
