A probehead for an electron spin resonance (ESR) dosimeter comprises a resonator and an insert extending into the resonator. The insert has a guide channel for bringing a sample into the resonator. The sample comprises a dosimeter substance. The guide channel is configured for receiving and guiding a test strip. The insert is provided with a first machine-readable code imprint. The insert is provided with at least one reference sample. A pressurized air unit is provided for blowing the sample out of the resonator after completion of a measurement. The insert has an opening on an upper side of the resonator. The opening is openly accessible for manually inserting dosimeter pills thereinto. The insert, further, is provided on the upper side with a pressurized air connector. The pressurized air connector is connected to an orifice via a pressurized air channel within the insert. The orifice is located within a lower, otherwise closed bottom of the guide channel. The sample substance comprises a chromium-doped magnesium oxide (Cr:MgO). The magnesium oxide is doped with the isotope Cr.

Described herein are systems, devices and methods to increase the accuracy of intravascular catheter placement, and to improve electrocardiogram (ECG), intravascular electrogram, and ultrasound Doppler signal processing to detect the Superior Vena Cava (SVC) area. Embodiments of the invention are intended to place an intravascular catheter within the lower ⅓ of SVC to the junction of the SVC and the right atrium (RA)—called the cavoatrial junction (CAJ). In particular, the improved accuracy of CAJ location detection during an intravascular catheter placement can be provided by optimization of ECG parameters and ultrasound Doppler signal using Neuro-Fuzzy logic and/or other processing techniques.
