Final answer:
The correct sequence in the receiver functions during image production in medical ultrasound is amplification, demodulation, compression, reject, and compensation.
Step-by-step explanation:
The correct order of steps in the receiver function during image production in medical ultrasound is:
- Amplification
- Demodulation
- Compression
- Rejection (often termed reject)
- Compensation
The process begins with the amplification of the electrical signals received from the transducer, which have been reflected back by tissues. Then, demodulation occurs, a process that converts the received high-frequency signals into a form more suitable for processing. After demodulation, compression of the signal's dynamic range takes place, which helps in displaying the image in a form that can be easily interpreted visually. Following compression, any unwanted signals are eliminated through a 'reject' function, which removes noise and enhances image clarity. Finally, compensation adjusts the brightness of the image to account for the loss of signal strength at different depths.
