Abstract: To establish reference standards for ocular ultrasound and biometry, 24 cinereous vultures (Aegypius monachus) (45 eyes) underwent B-rnode and
A-mode ultrasonographic examination using a 12.5-MHz probe.
Typically, three modes are obtainable in the ultrasonic diagnosis systems; there are
A-mode, B-mode and M-mode.
A prominent example is a single fibre optical coherence tomography (OCT) development, which delivers
A-mode measurements of the distance between the fibre and the retina (see Figure 3B iii).
An
A-mode, or amplitude mode, transducer relies on a narrow beam to scan tissue discontinuity and produces a spike on a graph.
A-mode ultrasonic biometry using 10 MHz linear transducer in amplitude mode was used to measure different intraocular distances (anterior chamber depth, lens thickness and axial length).
The solution: replace B2 cabinets with C1 cabinets to be used primarily in recirculating
A-modeAt the time of performance testing, ultrasound scanning of the back was conducted with amplitude mode (
A-mode) scanners.
An
A-mode, or amplitude-mode, transducer relies on a narrow beam to scan tissue discontinuity and produces a spike on a graph.
The transducer was placed in a longitudinal position (sagittal plane) until optimal Bscan images, according to echoes of the
A-mode, were obtained.
Although this control strategy works well, in future work we will simulate the SEMG-based 1-DOF prosthetic hand to collect the SMG from both the extensor and flexor with a multichannel
A-mode ultrasound system for higher control accuracy.
A statistical approach and parameters of
A-mode were used for image texture analysis.
An
A-mode SOU was not performed because of the patient's lack of cooperation.
