Question

A processing technique called temporal subtraction utilizes a _image which is subsequently superimposed with a _ image to produce _ image.

1. mask, subtracted, contrast
2. contrast, mask, subtracted
3. mask, contrast, subtracted
4. subtracted, mask, contrast

Answer 1

Temporal subtraction is a medical imaging technique that uses a mask image combined with a contrast image to create a subtracted image highlighting changes over time.

Step-by-step explanation:

The student is asking about a medical imaging processing technique known as temporal subtraction. This technique involves taking a mask image, which serves as a reference, and then superimposing it with a new image, referred to as the contrast image. The result of this process is a subtracted image, where the changes between the two images are highlighted, enhancing the visibility of temporal changes in the anatomy or pathology.

In other words, the correct sequence for the temporal subtraction technique is to start with a mask image, then combine it with a contrast image, and finally produce a subtracted image. Therefore, the answer to the student's question would be: 'A processing technique called temporal subtraction utilizes a mask image which is subsequently superimposed with a contrast image to produce a subtracted image.'
