“…It can configure frequency of operation and pulse length to optimize the image quality. The FPGA will also generate pulse repetition rate control signal of frequency based on depth of interest [13]. Pre-calculated delay profile per scanline are stored in FPGA register block memory to reduce the computational burden [14].…”

Abstract-In commercial ultrasound systems, the transmit module typically generates the time delayed excitation pulses to steer and focus the acoustic beam. However, the ultrasound transmitter module in these systems has limited access to medical ultrasound researchers. In this paper, we have presented the development of a programmable architecture for 8-channel ultrasound transmitter for medical ultrasound research activities. The proposed architecture consists of 8 transmit channels and Field Programmable Gate Array (FPGA) based configurable delay profile to steer acoustic beam, transmit frequency and pulse pattern length depending on the medical application. Our system operates in pulse-echo mode, with ultrasound transmit frequency up to 20 MHz, excitation voltage up to 100 Vpp, and individual channel control with single high speed Serial Peripheral Interface (SPI). Pre-calculated delay profiles per scanline are generated in Matlab, based on physical parameters of 8 element linear transducer array which are used to steer and focus the ultrasound beam. An experiment is carried with our transmit module to transmit ultrasound into gelatin phantom, acquired echoes and processed for B-mode imaging. The results show that this transmit platform can be used for ultrasound imaging researches and also for medical diagnosis.

“…In practice, however, one sees that major technological development has occurred, including high-power efficient pocket-controllers [60] and portable controllers for remote locations [61] [62]. Programmable, low-cost machines are needed, as well as those for real-time clinical use, and to this end efforts in research and development are currently being carried out [63].…”

This paper introduces the reader to a review and analysis of various ultrasound (us) applications in the medical field. First, the transducer is shown, along with a diagram of the basic electronics that it uses to generate and receive signals that allow the reconstruction of images, for medical purposes. Also, us practical uses in medical therapy is shown. This subject is addressed by combining the physical principles involved in the us application, with the implemented technology and the modes of operation for non-invasive studies of pathologies related to brain, heart, and eyes such as injuries, tumors and hematomas. The methodology used in this article also suggests an analysis method for the us scientific and technological research principles combined for their implementation in medical applications.Keywords: ultrasonic transducer, piezoelectric, transmitter, receiver, converter, modes ResumenEn este trabajo se presenta al lector una revisión y análisis de diferentes aplicaciones del ultrasonido (us) en el campo médico.
