Massively parallel diffuse optical tomography
| DWPI Title: Diffuse optical tomography system for generating volumetric image of human tissue, has sensor systems which output electrical signals indicative of transmission phases and amplitudes of portions of transillumination beam |
| Abstract: Diffuse optical tomography systems and methods are described herein. In a general embodiment, the diffuse optical tomography system comprises a plurality of sensor heads, the plurality of sensor heads comprising respective optical emitter systems and respective sensor systems. A sensor head in the plurality of sensors heads is caused to act as an illuminator, such that its optical emitter system transmits a transillumination beam towards a portion of a sample. Other sensor heads in the plurality of sensor heads act as observers, detecting portions of the transillumination beam that radiate from the sample in the fields of view of the respective sensory systems of the other sensor heads. Thus, sensor heads in the plurality of sensors heads generate sensor data in parallel. |
| Use: Diffuse optical tomography system for generating volumetric image of human tissue, such as breast tissue, brain tissue, or bone tissue. |
| Advantage: The volumetric image can be generated relatively quickly (e.g., less than two minutes) due to the massively parallel acquisition of illumination data. The diffuse optical tomography system is well-suited for inspecting high-voltage potting, since an absorption spectrum of high-voltage potting changes locally in the region where electrical breakdown has occurred. |
| Novelty: The tomography system (100) has optical emitter systems (116,120,124,128) that emit a transillumination beam towards a sample (102). Sensor systems (118,122,126,130) are positioned at different locations about the sample to detect, in parallel, respective portions of the transillumination beam that exit the sample. The sensor systems output respective electrical signals that are indicative of respective transmission phases of the respective portions of the transillumination beam and respective amplitudes of the respective portions of the transillumination beam detected by the sensor systems. |
