According to one embodiment, an X-ray computed tomography apparatus includes an X-ray tube, a detector, and processing circuitry. The X-ray tube emits X-rays. The detector detects X-rays that have been emitted from the X-ray tube and have passed through the subject. The processing circuitry sets an imaging condition. The processing circuitry evaluates the imaging condition based on information on a lower limit range of a count value of the detected X-rays that may cause image degradation.

Embodiments herein disclose systems, methods, and computer-readable media for intelligently monitoring radiation exposure values. The intelligent monitoring can monitor an amount of radiation a clinician is exposed to (via exams already performed) and identify how much radiation is acceptable for continued exposure before exceeding an exposure threshold value within a predetermined time period. Additionally, the system described herein can provide insights into how many procedures of a particular type a clinician is available to complete before expiration of the predetermined time period. The monitoring data can be provided via a graphical user interface and can be integrated into a scheduling system, an electronic health records system, etc., to provide meaningful insights for resource management.

A personal radiation and density meter system includes a housing, a radiation detection subsystem and a radiation emitting sub-system. The housing includes an interior portion configured as an interior space, and a slot. The radiation detection sub-system includes a personal radiation dosimeter positioned in the slot. The radiation emitting sub-system includes a shield assembly, a source, an actuator, a trigger, and an aperture.

A portable electronic dosimeter is described that comprises a plurality of detectors each configured to detect a type of ionizing radiation, wherein each detector is associated with an amplifier configured to produce an output in response to a plurality of detected photons of the ionizing radiation and an event counter configured to produce one or more counts in response to the detected photons of the ionizing radiation over an integration time; and a processor configured to receive the one or more counts from each of the counters and determine if there is coincidence of the one or more counts of all the detectors, wherein if there is coincidence the processor is configured to provide an over range alarm signal.

A portable detection apparatus can include a housing, a first detector for detecting ionizing radiation from a first subject and a second detector within the housing for the detecting the background radiation. A shield within the housing can surround the first and second detectors and define a shield aperture around the first and second detectors for radiation from the subject to enter the housing. A radiation blocking member can substantially block at least a portion of the ionizing radiation from reaching the second detector, whereby radiation detected by the second detector comprises substantially only the background radiation. A processor module can be connected to the first and second detectors for determining the amount of ionizing radiation detected by the first detector attributable to secondary radiation.

A mobile audio mesh distribution (MAD) system/method allowing synchronized audio distribution to modular audio modules (MAMs) and/or drone delivery aircraft (DDA) in mesh audio network (MAN) is disclosed. The system/method utilizes a computer control system (CCS) that communicates wirelessly using a plurality of RF transceivers (RFT) over a RF mesh network (RMN) with one or more MAM that are configured to independently communicate with each other and automatically determine if audio updates are required from the CCS. The MAM are configured to query other MAMs in the RMN to determine if a connected MAM has updated audio/text (UAT), and if so, to download the UAT and schedule audio playback on a speaker. Messages may be transmitted to the MAM in the event of an emergency, terrorist event, or a physical event detected (PED) using prerecorded or updated audio that trigger immediate or scheduled playback by the MAM.
