Disclosed herein is an endoscope comprising: an insertion tube; a radiation detector configured to detect radiation particles in a first range of energy and radiation particles in a second range of energy.

An intraoral tomosynthesis imaging apparatus having an intraoral detector coupled to a frame or radio-opaque marker attached to its radiation facing surface without any frame attached, wherein the frame defines a target aperture for an incident radiation beam. An enclosure seats against the target aperture and houses at least one x-ray source configured to emit a radiation beam from each of a plurality of focal points within the enclosure A collimator is disposed to form a collimated radiation beam and direct the collimated beam through the target aperture and to the detector. A geometric calibration phantom having a plurality of radio-opaque markers is disposed in the path of the collimated beam. This arrangement is modified to operate as a regular intraoral imaging device by accommodating a high-power central source at the same or different distances as other sources from the detector and displacing the phantom from the field of view.

A wireless intraoral dental x-ray imaging sensor and method of use. The sensor optionally has a rechargeable battery located away from the edge of a PCB/ceramic substrate to enable encapsulation. The sensor has a compact microcontroller unit with several blocks including a radiolink, processing capacity, and a low power management system. Bit truncation and image compression take place on a readout substrate and/or on the MCU. External memory blocks allow for at least partial image storage for safety and as a backup.

Articles, systems, and methods for rapid administration and active pharmaceutical compositions to subjects exposed to radiation and/or toxins are provided by this disclosure. There are currently few interventional technologies to protect against long-term morbidity and mortality from exposure to radiation and chemical warfare. Furthermore, as commercially available technologies such as additive manufacturing and small-scale chemical reactors have become more prevalent, the risk of misuse of such technologies by terrorists and rogue nation states to manufacture nuclear, radiologic, and chemical weapons continues to increase. Articles, systems, and methods described herein combine sensing technologies with drug release components, in order to provide an approach for rapid diagnosis of and response to exposure to radiation and toxic agents.

Disclosed are devices, systems and methods for providing sterile and cost-affordable handheld surgical devices with tactile operable controls. In some aspects, a surgical device includes a surgical probe including a probe detector and a set of operable controls; an exterior shell casing including an opening at one end leading to an interior cavity structured to have a size and shape to fit the surgical probe within and position the probe detector in a first region and a handle of the surgical probe in a second region, in which the first region of the exterior shell casing is configured to be inserted into an incision of a patient's body and the second region is configured to provide a user of the surgical device utilization of the operable controls of the surgical probe through the exterior shell casing; and a cap attachable to the exterior shell casing to close the opening.

This invention provides a mapped dental Cone Beam Computer Tomography (CBCT) workspace for the planning of placement of dental implants in the oral cavity. The workspace includes a template coordinate system in the oral cavity of a patient by placing a radiographic template having at least three radiographic markers of predetermined shape, size, and positions in the oral cavity, wherein the predetermined position is relative to at least one anatomical feature (natural or artificial) in the oral cavity. With this method, only a single CBCT scan is required. The CBCT scan is used to create a CBCT workspace with a coordinate system based on the radiographic template. Within the workspace, Implant Planning Software can be used to plan dental implants.

Provided is a radiation detector that can allow an operator to more accurately identify a position of a body tissue into which radionuclides have been taken. A radiation detector includes: a probe which has a radiation detection element housed therein and which is insertable into a body; a reporting part provided to the probe; and a control part configured to cause the reporting part to operate in accordance with a result of detection of radiation, the detection being made by the radiation detection element.

A tethered laparoscopic probe is provided, the tethered laparoscopic probe for deployment through a trocar into a cavity of a subject to detect gamma radiation from a radiopharmaceutical administered to the subject. The laparoscopic probe comprises a probe head shaped for insertion through the trocar and configured to be freely moveable within the cavity. The probe head comprises an elongate casing comprising radiation shielding for inhibiting gamma radiation from passing through the probe head, the radiation shielding having a detection aperture for admitting gamma radiation. The probe head further comprises a gamma radiation detector arranged within the casing, the gamma radiation detector configured to detect gamma radiation through the detection aperture of the casing. The probe head further comprises means for, in use, facilitating the localization of a source of radiation from the radiopharmaceutical within the cavity. The laparoscopic probe further comprises a tether coupled to the probe head and for, in use, tethering the probe head through the trocar.

A radiation detector includes a wiring board, a first image sensor, a second image sensor, a first fiber optic plate, a second fiber optic plate, and a scintillator layer. The first fiber optic plate can guide light between a first light entering region and a first light exiting region. The second fiber optic plate can guide light between a second light entering region and a second light exiting region. One side of the first light entering region and one side of the second light entering region are in contact with each other. The first light exiting region is positioned on a first light receiving region. The second light exiting region is positioned on a second light receiving region. One side surface of a first side surface and one side surface of a second side surface exhibit shapes along each other and in contact with each other.

A method is disclosed for diagnosing and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a lower stenosis rate lesion to be treated first, catheters and an operation time can be reduced is to be treated first on a priority basis based on diagnostic data, deciding that a higher stenosis rate lesion is to be treated next, then treating the lesions substantially continuously.
