Abstract: An ultrasound diagnostic system includes: an ultrasonic probe having a plurality of transducers and configured to obtain a plurality of pieces of ultrasound image data of a subject, the transducers being arranged in a first direction and configured to transmit ultrasonic waves toward the subject and receive ultrasonic waves reflected from the subject; a moving mechanism configured to move the ultrasonic probe in the first direction and in a second direction; and a controller including a processor configured to perform a process including, causing the moving mechanism to move the ultrasonic probe based on a position of a blood vessel in an ultrasound image, and generating blood vessel map data indicating information related to the blood vessel by referring to an image data storage in which the plurality of pieces of ultrasound image data are stored in association with respective amounts of movement in the first and second direction.

Abstract: A transmission apparatus of a data transmission and reception system includes a number of converters, multipliers, adders and a transmission unit. The converters convert information-bit sequences b(0), b(1) and b(2), respectively, into encoded x(0), x(1) and x(2), respectively. The multipliers multiply respectively the encoded sequences x(0), x(1) and x(2) by constants a(0), a(1) and a(2). The adder adds a constant-times encoded sequence a(0)x(0) produced by a first multiplier as a result of multiplication to a constant-times encoded sequence a(1)x(1) produced by a second multiplier. A second adder adds an additive encoded sequence a(0)x(0)+a(1)x(1) produced by a first adder to a constant-times encoded sequence a(2)x(2) produced by a third multiplier. The transmission unit transmits an additive encoded sequence g(=a(0)x(0)+a(1)x(1)+a(2)x(2), produced by the second adder to an external apparatus as a transmitted signal g?.

Abstract: A high-performance decoding process allowing the degree of design freedom to be increased substantially has been implemented. A transmission apparatus (10) of a data transmission and reception system comprises converters (110), (111) and (112), multipliers (120), (121) and (122), adders (130) and (131) and a transmission unit 14. The converters (110), (111) and (112) convert information-bit sequences b(0), b(1) and b(2) respectively into encoded sequences x(0), x(1) and x(2) respectively. The multipliers (120), (121) and (122) multiply respectively the encoded sequences x(0), x(1) and x(2) by constants a(0), a(1) and a(2) respectively. The adder (130) adds a constant-times encoded sequence a(0)x(0) produced by the multiplier (120) as a result of multiplication to a constant-times encoded sequence a(1)x(1) produced by the multiplier (121) as a result of multiplication.
