"Written by leading experts in the field, Dr. Griffith et al. have produced, Diagnostic Ultrasound: Musculoskeletal, the most comprehensive and up-to-date reference on musculoskeletal ultrasound. One of the keys to understanding any imaging modality is anatomy and this aspect has been well covered in the opening section. This beautifully illustrated section covers all relevant ultrasound anatomy in detail. The next diagnostic imaging section deals with the full range of specific entities likely to be encountered when performing musculoskeletal ultrasound such as discrete soft tissues masses, tendon disorders, entrapment syndromes, vascular anomalies, subcutaneous, muscle, and joint disorders. The next differential diagnosis section is unique in looking at musculosketal ultrasound imaging from a completely different viewpoint. It addresses the differential diagnoses should you consider when faced with different clinical ultrasound scenarios such as, for example, a patient with a para-articular cystic mass or an echogenic subcutaneous mass. This section is particularly helpful to those less experienced with musculoskeletal ultrasound. Diagnostic Ultrasound: Musculoskeletal is ideally suited to guide intervention for either diagnostic or therapeutic purposes. With this in mind, the final section comprises an encompassing, up-to-date assessment of the indications, techniques and sequelae of all commonly employed ultrasound-guided musculoskeletal interventional procedures. This comprehensive book is written in an easy to access format, and is ideally suited to a busy musculoskeletal ultrasound practice. It is packed with useful information, supported by beautiful schematic diagrams, and carefully selected illustrative high quality ultrasound images"

"Jacobsite nanomagnetic particles with various size can be easily synthesized by using coprecipitation method. Samples are categorized into two synthesis condition, which is nonultrasonic assisted and ultrasonic assisted process. Samples are characterized with various methods to give understanding on their structure. Annealing process gave significant effect on the structure of the particles, thus provides better crystallinity on the annealed samples. The study shows that upon the annealing temperature of 300OC for four hours on nanomagnetic particles synthesized using ultrasonic are in Jacobsite phase; on the other hand we could have pure Jacobsite only by an hour of annealing when we subject the samples to ultrasonic treatment. Nanomagnetic particles size ranging from 4 nm to 16 nm are found after annealing process when samples are synthesized without using ultrasonic treatment. We have also obtained nanomagnetic particles with size ranging from 2 nm to 11 nm after annealing process when the samples are being exposed to ultrasonic treatment.

Rekonstruksi merupakan bagian penting dari proses pencitrran. Pada sistem pencitraan ultrasonik, untuk menghasilkan citra dilakukan tahap rekonstruksi sinyal akustik A ? Mode menjadi B ? Mode yang merupakan dasar dari sistem pencitraan ultrasonik. Untuk memperoleh hasil yang optimal, sebelum merekonstruksi citra yang sesungguhnya, dilakukan simulasi. Pada skripsi ini, simulasi dilakukan dengan menggunakan software COMSOL34 MULTIPHYSICS dan MATLAB R2007. Dengan menggunakan software COMSOL34 MULTIPHYSICS menerapkan metode elemen hingga dapat diperoleh data berupa sinyal A ? Mode yang selanjutnya sinyal tersebut diolah menggunakan software MATLAB R2007. Software MATLAB R2007 berfungsi untuk menampilkan citra dan menganalisis hasil. Citra yang dihasilkan dipengaruhi oleh beberapa faktor, seperti frekuensi, bandwitdh, lebar transducer, pengaruh mesh COMSOL34 MULTIPHYSICS dan grid transducer pada COMSOL34 MULTIPHYSICS . Semua faktor tersebut berpengaruh kepada resolusi, ketajaman, tingkat kecerahan citra yang dihasilkan."
