个人简介
Prompted by the neccessity of improving cardiac diagnosis by looking at the moving heart structures, Professor Bom was responsible for the development of the real-time multi-element linear array scanner in the early 1970s. His initial design in 1971, which he applied for a Dutch patent, consisted of only 20 crystals (each 4mm x 10mm). The probe face was 80mm long and 10mm wide. It operated at a frequency of 2.25 or 4.5 MHz sweeping at a frame rate of 150f/sec. The axial resolution was 1.25 mm at 3MHz while the beam width at 6 cm was 1cm. This abeit simple and inadequate design at that time has evolved into the very sophisticated real-time scanners that are widely available today. In collaboration with the Dutch company Organon Teknika, they produced the "Multiscan System", one of the earliest commercial linear array scanner in the world (Aloka® in Japan in 1971 also produced their first linear array scanner), mainly aimed for cardiac investigations. The transducers operated at either 2.25 or 4.5 MHz, again with 20 crystals producing 20 scan lines. The lateral resolution of this improved version at a dynamic range of 10dB was 3.7 mm at 6 cm and 6 mm at 10 cm depth. It did not sell very well though because of its relatively primitive resolution and its inability to image abdominal structures adequately.
