Final answer:

The readout portion of the pulse sequence acquires the signal data through frequency encoding, which is a part of the MRI technique used to generate images of internal body structures.

Step-by-step explanation:

The readout portion of the pulse sequence acquires or measures the signal data through frequency encoding. This process is a critical step in magnetic resonance imaging (MRI), which is a technique used in medicine to create images of the body's internal structures. During an MRI scan, various pulse sequences are used to manipulate and then measure the magnetic properties of atoms within the body, mainly hydrogen protons. The readout phase involves the application of a gradient magnetic field, causing the protons to resonate at different frequencies depending on their spatial location. This resonance is then translated into electrical signals by the receiving coils and further processed to construct an image, with each frequency providing information about a different spatial position within the body.
