    Abstract: Devices, systems, and methods for localized delivery of a chemotherapy, hormonal therapy, or targeted drug/biologic therapy to a target tissue area of an internal body organ of a patient. Computer systems may be used for planning and navigation in super selective drug delivery via a tracheobronchial airway. A catheter may be used to form a sealed treatment chamber in a natural lumen extending through the target tissue area. Air is purged from the chamber, which is then filled with a liquid drug solution for an adequate treatment session time, solution volume and drug concentration to saturate the target tissue area, thereby providing the treatment. The liquid drug solution may be circulated or recirculated through the chamber or maintained stationary therewithin to saturate the target tissue area. The chamber is evacuated at the end of the treatment session.

    Abstract: An optoacoustic probe for optoacoustic imaging of a volume, the optoacoustic probe having a distal end operable to contact the volume and a proximal end. The optoacoustic probe includes at least one primary light source and an auxiliary light source that is configured to generate auxiliary light carried through an optical window to a volume. A detection device is configured to detect signals generated from the auxiliary light or primary light reflecting from the volume or the optical window. A microcontroller including one or more processors is also provided, that receives the signals generated from the auxiliary light reflecting from the volume from the detection device, determines contact between the volume and the optoacoustic probe based on the auxiliary light reflecting from the volume, and prevents the at least one primary light source from generating light until the optoacoustic probe is contacting the volume.

    Abstract: Aspects of the technology described herein relate to apparatuses and methods for performing elevational beamforming of ultrasound data. Elevational beamforming may be implemented by different types of control circuitry. Certain control circuitry may be configured to control memory such that ultrasound data from different elevational channels is summed with stored ultrasound data in the memory that was collected at different times. Certain control circuitry may be configured to control a decimator to decimate ultrasound data from different elevational channels with different phases. Certain control circuitry may be configured to control direct digital synthesis circuitry to add a different phase offset to complex signals generated by the DDS circuitry for multiplying with ultrasound data from different elevational channels.

    Abstract: Methods and systems for assessing membrane potential are provided. In some embodiments, the methods and systems, described herein, may allow spatial patterns of membrane potential to be facilely obtained. For instance, a method may comprise transferring a population of cells from a tissue to a substrate. The transfer process may substantially maintain the viability of and/or the spatial relationship between the cells. The cells on the membrane may be exposed to a voltage sensitive dye. The dye may allow the membrane potential of individual cells on the substrate to be imaged or otherwise detected. The individual cell membrane potentials when imaged together on the substrate may form a spatial membrane potential pattern. The spatial membrane potential pattern may be used to assess one or more physiological characteristics of the cells. The methods and systems may be used for a wide variety of applications, including the assessment of biopsies.
