Hand Held Metal Detector Features:
To resolve these problems the PD240CH portable metal detector which combines high sensitivity to ferromagnetic metals with immunity to non-ferromagnetic metals. Additionally, by quickly changing the operational mode it can become a complete metal detector capable of detecting any type of metal material.
The PD240CH has 3 analysis modes selectable via a keypad interface:
1 HEAD: high sensitivity to very small ferromagnetic objects. Total immunity to non-ferromagnetic items that could be located in the head. Designed to analyze the head, this setting allows discrimination of, for example, non-ferromagnetic dental implants. At the same time, it can detect, at a distance of some cm, ferromagnetic objects down to few mm size.
2 BODY: high sensitivity to small ferromagnetic objects. Total immunity to non-ferromagnetic objects even of large dimensions. Designed to analyze the whole body, this setting allows discrimination of, for example, non-ferromagnetic metal prostheses. At the same time, it can detect, at a distance of some cm, ferromagnetic objects down to few mm size.
3 ALL-METALS: high sensitivity to all types of materials. This setting allows detection of any ferromagnetic or non-ferromagnetic metal object, for example pacemakers, prostheses and vital support devices, and also any other object carried by the patient which should not be taken into the strong magnetic field area. This mode can also be used in the A&E environment, where there is a need to identify, for example, the presence of metal slivers in a patient following an accident or swallowing metal objects. To ensure optimum operating conditions for the PD240CH metal detector, the patient should be lying on a metal-free bed. This, especially in the All-metals mode, will ensure maximum effectiveness and reliability, avoiding the influence of metal parts.
The speed of operational mode changes in the PD240CH allows doctors to carry out a complete examination of the patient. By using all three modes, they can obtain an indication of any metals inside the patient and of their magnetic susceptibility. Together with written and verbal questionnaires, the doctor can thus get a clear picture of the risk situation and make the most appropriate decision. The control interface allows selection of the type of alarm wanted, acoustic and/or vibration. The visual signalling, together with the audio, provide feedback on the extent of the alarm by giving an indication, depending on the operational mode, of the size of the object in combination with its ferromagnetic characteristics. Alarm analysis is of the static type, and does not require movement of the detector relative to the object. It thus allows pinpointing of the object by searching for the point of maximum alarm signal. The PD240CH can also be configured using the HHMD Setup graphic interface, which allows personalization of the interface, of the energy-saving mode and of the sensitivity of the three operational modes. In this way it is possible to refine the analysis capabilities based on the specific needs encountered during use, increasing or reducing sensitivity to prioritize sensitivity to or discrimination of the devices and prostheses that may be in
the patients.
The growing awareness of the dangers in MRI scans requires an increase in preventive inspections so as to ensure the safety of patients and the operators around them. A written questionnaire filled in by the patient can be prone to errors due to misinterpretation or ignorance of the typology of any implants or prostheses inside the body. A preventive inspection by a metal detector would eliminate banal mistakes and allow the doctor to better assess the situation. The PD240CH hand-held metal detector incorporates the benefits of magnetometers and metal detectors, allowing a rapid analysis of the patient in the search for any ferromagnetic metal objects while discriminating all the objects, prostheses and implants that are not dangerous in MRI. In addition, the PD240CH can be used in environments where the use of a complete metal detector is required to search for any type of metal.
