“…3D visualisation treatment planning can be used in the quantitative calculation of tumour volume and the distance between the tumour and surrounding vital structures, as well as accurate simulation of 3D thermal fields and planning of the puncture pathway. 3D visualisation preoperative planning has been applied in liver thermal ablation [18,24,25]. On the basis of the characteristics and clinical application requirements of US-guided PMWA for larger RCC, we combined 3D visualisation treatment planning, US-guided PMWA, artificial ascites and a thermal monitoring system for larger RCC.…”

Materials and methods:The results from 20 patients with 20 larger RCCs treated with a 3D visualisation operative treatment planning system and US-guided PMWA were reviewed retrospectively. The patients were followed up by contrast-enhanced images at 1, 3, and 6 months and every 6 months thereafter. The outcomes of overall survival and local tumour progression rate were statistically analysed. Results: The median follow-up period was 26 months. The mean time of ablation for one tumour was 1.1 ± 0.3 sessions. The average number of ablation points of one tumour was 4.5 ± 0.9. The mean output power of ablation was 50.50 ± 2.2 W. The mean time of ablation for one tumour was 1374.4 ± 391.1 s. Artificial ascites was used in 12 (60%) tumours adjacent to the intestinal tract, and thermal monitoring system was used in all tumours (100%). Technical effectiveness and metastasis-free status were achieved in all tumours. The 1-and 2-year local tumour progression rates were both 5%. The cancer-specific survival rate and 2-year overall survival rates were both 100%. No severe major complications occurred. There was no significant difference in creatinine or urea nitrogen before or 3 days after ablation. Conclusions: Combination therapy of 3D visualisation operative treatment planning system and USguided PMWA appeared to be a safe and effective technique for the management of larger RCCs, which could improve clinical efficacy.

“…In this study we presented a simulation environment for microwave thermal ablation (MWA) under the guidance of ultrasound developed in combination with our previous research [25][26][27][42][43][44]46] and other research [28][29][30][31][32][33][34][35][36][37][38][39][40][41]45]. Using these studies can save resources by avoiding 'reinventing the wheel', and can shorten the development cycle.…”

“…Many researchers [33][34][35][36] have reported that pre-operative planning methods based on 3D image data are feasible for thermal ablation. Some computer 3D models of thermal therapy taking into account patient-specific anatomies have been developed for hyperthermia applications [37][38][39][40][41].…”

The purpose of this study was to provide a simulation therapy environment for microwave thermal ablation (MWA) under the guidance of ultrasound, and to present an inexpensive and portable simulator built on real patient-based pre-operative computed tomography (CT) data. We established an experimental simulation system for teaching MWA and present the results of a preliminary evaluation of the simulator's realism and utility for training. The system comprises physical elements of an electromagnetic tracking device and an abdominal phantom, and software elements providing three-dimensional (3D) image processing tools, real-time navigation functions and objective evaluation function module. Details of the novel aspects of this system are presented, including a portable electromagnetic tracking device, adoption of real patient-based pre-operative CT data of liver, operation simulation of MWA, and recording and playback of the operation simulation. Patients with liver cancer were selected for evaluation of the clinical application value of the experimental simulation system. A total of 50 consultant interventional radiologists and 20 specialist registrars in radiology rated the simulator's hardware reality and overall ergonomics. Results show that the simulator system we describe can be used as a training tool for MWA. It enables training with real patient cases prior to surgery, and it can provide a realistic simulation of the actual procedure.

“…Traditional trajectory planning methods presented in [2][3][4][5][6] tried to explore the practicability of computer aided design in puncture surgery planning. References [7][8][9][10][11][12][13][14] presented visualization methods to display puncture pathways in optimal views and better interactive methods to make it easier for surgeons to observe and adjust the planned puncture routes. References [15][16][17][18][19][20][21][22] focused on automatic or semiautomatic methods to output precisely optimized pathways.…”

Percutaneous surgeries in the craniofacial region bring benefits to patients. Small cut downs relieve pain and reduce bleeding. Preoperative puncture trajectory planning is a critical procedure for percutaneous surgeries. Methods have been proposed to help surgeons make good decisions in trajectory planning both in automatic and interactive ways. Even though, optimizing a puncture pathway in craniofacial region is still challenging. In this paper, we develop an automatic trajectory recommendation method for craniofacial surgeries based on quantitative criteria: insertion depth, the visible size of the target area, absolute visible size of the target (AVS), relative visible rate of the target (RVR), and vital distance (VD). We also introduce visual analysis methods such as scatter plots and parallel coordinates for refining automatic recommendation results. We integrate our methods into a preoperative surgery planning system and evaluate it on virtual patients.

Visualization support for the planning of hepatic needle placement

Abstract: The proposed visualization approach can both accelerate the access path planning for radiofrequency ablation in the liver and facilitate the differentiation between safer and less safe paths.
