Therefore, the early screening of breast cancer has a decisive role.
Compared to X ray computer tomographic imaging (X-ray Computed Tomography) and magnetic resonance imaging
(Magnetic Resonance Imaging), ultrasound tomography (Ultrasound Computed Tomography, letter
Claim USCT) have many advantages, such as no ionising radiation, non-intruding, it is a kind of promising mammary gland that without mammary gland compression and cost is relatively low
Cancer methods for screening.
Some researches show that may recognize that variety classes in conjunction with priori knowledge by the group sound velocity distribution map that USCT is rebuild
Cancerous issue and normal tissue.
The deficiency that annular ultrasonic transducer array has difficulty of processing big, at high cost.In addition, by the mould of annular array unit
When quasi- position is converted to digital coordinates, it may appear that match inaccurate situation, bring error to the calculating of image reconstruction.
Line style ultrasound transducer array has the advantages that easy to process and cost is relatively low.In addition, the array element of line style
Analog position and digital coordinates can be matched accurately.
Compared to the ultrasound transducer array that traditional B ultrasound imaging mode can only acquire reflection signal, around the ultrasound of closo
Transducer array can acquire ultrasound simultaneously and pass through transmission signal caused by testee, reflection signal and high order diffraction signal
Deng.
It can acquire most complete mammary gland data by the way of prone position, but more difficult cannot lie prone long applied to older
The person of being screened.The comfort of patient can be met by the way of dorsal position, but the mammary gland due to belonging to soft tissue can be because of position not
Significantly deformation is generated together, so the mammary gland data that can be collected when dorsal position are less.Therefore, acquisition mode needs synthesis to examine
Consider the comfort level for the person of being screened and the precision of state of an illness detection.
Summary of the invention
In view of this, being chromatographed the object of the present invention is to provide a kind of based on the three-D ultrasonic of sitting formula and linear array
