“…Brachytherapy treatment of prostate carcinoma was first described in 1909 (Aronowitz et al 2011). In 1981 Kumar and Bartone (1981) introduced the transperineal approach with iodine-125 seeds for continuous low dose rate (LDR) brachytherapy, which is preceding modern LDR brachytherapy with intra-operative dosimetric planning (Kaplan et al 2000).…”

This work discusses a novel strategy for inverse planning in low dose rate brachytherapy. It applies the idea of compressed sensing to the problem of inverse treatment planning and a new solver for this formulation is developed. An inverse planning algorithm was developed incorporating brachytherapy dose calculation methods as recommended by AAPM TG-43. For optimization of the functional a new variant of a matching pursuit type solver is presented. The results are compared with current state-of-the-art inverse treatment planning algorithms by means of real prostate cancer patient data. The novel strategy outperforms the best state-of-the-art methods in speed, while achieving comparable quality. It is able to find solutions with comparable values for the objective function and it achieves these results within a few microseconds, being up to 542 times faster than competing state-of-the-art strategies, allowing real-time treatment planning. The sparse solution of inverse brachytherapy planning achieved with methods from compressed sensing is a new paradigm for optimization in medical physics. Through the sparsity of required needles and seeds identified by this method, the cost of intervention may be reduced.

“…They found that only 18.2 min was added to operating time and dosimetric evaluation was equivalent to the preplan method. Kaplan et al 30 also found equivalent dosimetric results, as did Beyer's group who had a total surgical time of less than 1 h. 40 Simply putting needles into the prostate gland causes changes in position, size and shape. 33,41 With this in mind modern techniques plan after needles have been placed.…”

Purpose: To summarise the practical aspects of the development of techniques of interstitial permanent prostate brachytherapy (PPB) implantation. Prostate brachytherapy dates back to Pasteau's publication in 1913 describing the insertion of a radium capsule into the prostatic urethra to treat carcinoma of the prostate. Various implantation methods were employed but with unsatisfactory results until the development of the transrectal ultrasound in the 1980s. The subsequent two-stage Seattle technique allowed for a planned homogenous distribution of radioactive sources throughout the gland resulting in biochemical control comparable to surgical and external beam radiotherapy series. With the advent of advanced computer software and improved imaging, the technique has developed accordingly to a single stage procedure with ontable dosimetric assessment. The principles of targeting dose to the prostate while avoiding surrounding organs at risk remain as relevant today as nearly a century ago. There is an array of techniques to consider for the novice PPB provider. Whether the evolution of PPB techniques will translate into improved biochemical control is yet to be seen.

“…In their study, MRI image sets were registered to the ultrasound images in real-time during the biopsy. Kaplan et al (2000) used a hardware setting similar to the hardware utilized for brachytherapy implant procedure and stereotactically targeted the abnormal areas of the tissue as identified on MRI images. More recently, a remotely actuated manipulator for accessing the prostate tissue under magnetic resonance imaging guidance was introduced (Fichtinger et al 2002;Krieger et al 2005).…”
