BIOLOGICAL INFORMATION PROCESSING APPARATUS AND BIOLOGICAL INFORMATION PROCESSING PROGRAM
First Claim
1. A biological information processing apparatus, comprising:
- a conversion element which receives an ultrasonic wave transmitted from a subject and converts the ultrasonic wave into an analog signal;
an analog-digital converting unit which converts the analog signal into a digital signal;
a first memory which records the digital signal;
a signal processing unit which outputs information on an inside of the subject from the signal recorded in said first memory;
a second memory which records information on an ineffective area, which is an area for which it is determined that information need not be recorded, out of areas through which the ultrasonic wave passes; and
a controlling unit which controls activation of said analog-digital converting unit or recording to said first memory,wherein said controlling unit stops the activation of said analog-digital converting unit or recording to said first memory in a period in which information from a point in the ineffective area can be received based on the information recorded in said second memory.

Abstract
A biological information processing apparatus, including: a conversion element which receives an ultrasonic wave transmitted from a subject and converts the ultrasonic wave into an analog signal; an analog-digital converting unit; a first memory which records a digital signal; a signal processing unit which outputs information on an inside of a biological body from the signal recorded in the first memory; a second memory which records information on an ineffective area, for which information need not be recorded; and a controlling unit which controls activation of the analog-digital converting unit or recording to the first memory, wherein the controlling unit stops the activation of the analog-digital converting unit or recording to the first memory in a period in which the ultrasonic wave transmitted from the ineffective area is received based on the information recorded in the second memory.

7. A biological information processing program for causing a processing unit to execute:
-
a step of receiving an analog signal which is generated by a conversion element converting an ultrasonic wave transmitted from a subject; an analog-digital converting step of converting the analog signal into a digital signal; a recording step of recording the digital signal into a first memory; a step of outputting information on an inside of the subject from the signal recorded in the first memory; a step of recording, to a second memory, information on an ineffective area, which is an area for which it is determined that information need not be recorded, out of areas through which the ultrasonic wave passes; and a controlling step of controlling execution of the analog-digital converting step or execution of said recording step, wherein said controlling step includes stopping the execution of said analog-digital converting step or execution of said recording step in a period in which information from a point in the ineffective area can be received based on the information recorded in the second memory.
