Final answer:
MR imaging of 288 x 160 would be smaller compared to 512 x 416 matrix.
Step-by-step explanation:
Magnetic resonance (MR) imaging uses a matrix of pixels to represent the image. The size of the matrix is determined by two dimensions, typically denoted as width and height. In this case, the first matrix is 288 x 160, while the second matrix is 512 x 416. The numbers represent the number of pixels in each dimension.
Comparing the two matrices, the first matrix (288 x 160) has a smaller number of pixels compared to the second matrix (512 x 416). Therefore, the correct answer is option A) Smaller, Larger. The first matrix will result in a smaller image, while the second matrix will result in a larger image.
