Abstract: Methods and apparatus for determining a position of a heart pump in a heart of a patient are described. The method includes receiving a pressure signal from at least one pressure sensor arranged on the heart pump, generating a histogram of values observed within a time window associated with the pressure signal, and determining the position of the heart pump based, at least in part, on a morphology of the histogram.

Abstract: A compact diffuse optical tomography system for generating a functional image of a lesion region is provided. The system includes a source subsystem, a probe, a detection subsystem, and a computing device. The source subsystem includes laser diodes and a laser diode driver board. The probe is configured to emit the optical waves generated by the source subsystem toward the lesion region and detect optical waves reflected by the lesion region. The detection subsystem includes a miniaturized detection board and a miniaturized data acquisition board. The miniaturized detection board includes a photomultiplier tube configured to convert the optical waves detected by the probe to electrical signals. The miniaturized data acquisition board is configured to convert electrical signals outputted by the miniaturized detection board to digital signals. The computing device is configured to receive the digital signals, reconstruct the functional image, and display the functional image.
