Background
A method for the identification of semi‐active fiducial magnetic resonance (MR) markers is presented based on selectively optically tuning and detuning them.Methods
Four inductively coupled solenoid coils with photoresistors were connected to light sources. A microcontroller timed the optical tuning/detuning of coils and image collection. The markers were tested on an MR manipulator linking the microcontroller to the manipulator control to visibly select the marker subset according to the actuated joint.Results
In closed‐loop control, the average and maximum were 0.76° ± 0.41° and 1.18° errors for a rotational joint, and 0.87 mm ± 0.26 mm and 1.13 mm for the prismatic joint.Conclusions
This technique is suitable for MR‐compatible actuated devices that use semi‐active MR‐compatible markers. 相似文献2.

Background
Transoral robotic surgery (TORS) using the Single-Port system (SPS) relies on electrocautery, limiting its applications in the upper aerodigestive tract. We evaluated the feasibility of a CO2 delivery system for the SPS.Methods
Otolaryngology residents performed a cutting exercise using a handheld CO2 laser and participated in a cadaveric oropharyngeal dissection using the SPS with monopolar cautery (SP + EC) and CO2 laser (SP + CO2). Residents completed the System Usability Scale (SUS) questionnaire to evaluate these techniques.Results
The same laser fiber was used for all combined dissections. The handheld CO2 laser, SP + EC, and SP + CO2 demonstrated similar SUS scores. On individual domain scores, SP + CO2 received less favorable ratings compared to the handheld CO2 laser for complexity, integration, and cumbersome experience (p < 0.05). On subgroup stratification, less TORS experience was associated with worse SUS scores.Conclusion
SP-guided CO2 laser delivery is a viable alternative to electrocautery in robotic surgery, and should be considered when performing TORS. 相似文献3.

Background
We analyze our outcomes utilizing imported allografts as a strategy to shorten wait list time for pancreas transplantation.Methods
This is an observational retrospective cohort of 26 recipients who received either a locally procured (n = 16) or an imported pancreas graft (n = 10) at our center between January 2014 and May 2017. Wait list times of this cohort were compared to UNOS Region 9 (New York State and Western Vermont). Hospital financial data were also reviewed to analyze the cost‐effectiveness of this strategy.Results
Imported pancreas grafts had significantly increased cold ischemia times (CIT) and peak lipase (PL) levels compared to locally procured grafts (CIT 827 vs 497 minutes; P = .001, PL 563 vs 157 u/L; P = .023, respectively). There were no differences in graft or patient survival. The median wait time was significantly lower for simultaneous kidney‐pancreas transplants at our center (518 days, n = 21) compared to Region 9 (1001 days, n = 65) P = .038. Despite financial concerns, the cost of transport for imported grafts was offset by lower standard acquisition costs.Conclusions
Imported pancreas grafts may be a cost‐effective strategy to increase organ utilization and shorten wait times in regions with longer waiting times. 相似文献4.

Background
Impairment of haptic perception by surgical gloves could reduce requirements on haptic systems for surgery. While grip forces and manipulation capabilities were not impaired in previous studies, no data is available for perception thresholds.Methods
Absolute and differential thresholds (20 dB above threshold) of 24 subjects were measured for frequencies of 25 and 250 Hz with a Ψ‐method. Effects of wearing a surgical glove, moisture on the contact surface and subject's experience with gloves were incorporated in a full‐factorial experimental design.Results
Absolute thresholds of 12.8 dB and ?29.6 dB (means for 25 and 250 Hz, respectively) and differential thresholds of ?12.6 dB and ?9.5 dB agree with previous studies. A relevant effect of the frequency on absolute thresholds was found. Comparisons of glove‐ and no‐glove‐conditions did not reveal a significant mean difference.Conclusions
Wearing a single surgical glove does not affect absolute and differential haptic perception thresholds. 相似文献10.
