Abstract
A cross-modal interface includes a multi-modal sensor configured to concurrently receive multiple input signals with each input signal being provided from a different imaging modality and in response thereto providing a single cross-modal output signal to processing circuitry which processes the single cross-modal output signal provided thereto and generates an output comprising information obtained or otherwise derived from each of or a combination of the different imaging modalities.
Claims20
A cross-modal interface comprising:
- a substrate;
- at least one sensor having source and drain terminals, a frontside gate terminal, and a backside gate terminal disposed on the substrate, said sensor comprising a radiation sensitive material disposed about at least portions of the substrate and coupled to at least one of the source, drain, frontside gate, and backside gate terminals, the sensor responsive to a first input associated with a first imaging modality received at one of the frontside and backside gate terminals and a second input associated with a second imaging modality received via the radiation sensitive material;
- and
- wherein the at least one sensor is configured such that a conductivity characteristic between the source and drain terminals changes in response to the first input associated with the first imaging modality received at the frontside or backside gate and the second input associated with the second imaging modality received via the radiation sensitive material such that the cross-modal interface generates a cross-modal interface signal representative of the first input associated with the first imaging modality received at the frontside or backside gate and the second input associated with the second modality received via the radiation sensitive material.
A method for cross-modal signal generation comprising:
- receiving, at a frontside gate terminal of a sensor a first input associated with a first imaging modality;
- receiving a second input associated with a second imaging modality at a backside gate terminal of the sensor;
- generating an output signal representative of the first input associated with the first imaging modality received at the frontside gate and the second input associated with the second imaging modality received at the backside gate.
A cross-modal interface for one or more imaging modalities comprises:
- at least one sensor provided from a plurality of field effect transistors (FETs), each of the FETs having source and drain terminals and at least one gate terminal;
- a radiation sensitive material disposed to be coupled to at least one of the FET terminals, the sensor responsive to a first input associated with a first imaging modality received at the at least one gate terminal and further responsive to a second input associated with a second imaging modality received at the radiation sensitive material wherein the sensor is configured so that the conductivity between the source and drain terminals changes in response to either the first input associated with the first imaging modality or the second input associated with the second imaging modality.
